Storage temperature must be between -20°C and 60°C.The isolation transformer eliminates any electrical continuity between AC shore power and the vessel. It is essential for safety and eliminates the need for galvanic isolators and polarity alarms.2.1. Electrical safetyElectrical safety is taken for granted in the case of a standard on-shore installation. A circuit breaker will trip, or a GFCI (Ground Fault Circuit Interrupter) will trip in case of a short circuit or a current leakage to ground. Connecting the ground wire of theshore-side supply to a vessel's metal parts will result in galvanic corrosion.Bringing only the live and neutral wire onboard results in an unsafe situation because GFCIs will not work, nor will a breaker trip in case of a short circuit to a metal part on the vessel.2.2. Galvanic corrosion preventionGalvanic corrosion occurs when two dissimilar metals in electrical contact are simultaneously exposed to an electrically conducting fluid. Seawater and, to a lesser extent, freshwater are such fluids. In general, the more active alloy of the couple corrodes preferentially, while the less active (more noble) material is cathodically protected. The rate of galvanic corrosion is a function of several variables, including area ratios, the conductivity of the fluid, temperature, the nature of the materials, etc.It is a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact, it can occur on any vessel as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve your sacrificial anodes and attack the shaft, propeller and other metal parts in contact with water when the vessel is connected to the shore-side supply. It might therefore be tempting not to connect the ground conductor: this is, however, extremely dangerous because a GFCI will not work, nor will a circuit breaker trip in case of a short circuit to a metal part on the vessel.The best solution to avoid galvanic corrosion and, at the same time, prevent any unsafe situation is to install an isolation transformer to connect to the shore-side supply. The isolation transformer eliminates any electrical continuity between shore power and the vessel. The shore power is fed to the transformer's primary side, and the vessel is connected to the secondary. The isolation transformer completely isolates the vessel from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI or a breaker will trip in case of a short circuit.The shore ground connected to immersed metals of the vessel causesgalvanic corrosion.The shore ground is isolated from the vessel ground, and galvaniccorrosion originating from the shore connection is blocked.2.3. Converting voltagesThe isolation transformer converts the input voltage with a 1:1.05 ratio. The 1:1.05 transformer ratio boosts the output voltage of the isolation transformer by 5%. This is to compensate for shore power voltage drops that are a common occurrence in marinas.• A 230V input becomes 240V.The isolation transformer can be used in 50Hz or 60Hz systems. However, the isolation transformer cannot convert frequencies from 50Hz to 60Hz or vice versa.2.4. Soft startSoft start is a standard feature of a Victron Energy isolation transformer. It will prevent the shore power circuit breaker from tripping due to the transformer inrush current.2.5. Internal wiring diagramInternal wiring diagram of the isolation transformer.2.6. Safety when the vessel is out of the waterIt is recommended, for optimal safety, to connect the shore earth to the vessel's earth when the vessel is out of the water, in winter or for maintenance. The isolation transformer has a facility for this.3.1. What's in the boxThe isolation transformer ships with the following items:3.2. Connections overviewThe Earth link wires used in points 2 and 4 are included with the transformer. They have a core surface areaof 6mm² (10AWG) and are connected to a 6.3mm spade terminal. Depending on local electrical regulations,this cable surface area might not be large enough to carry the potential fault currents of the AC systemwhere the isolation transformer is used. If wires with a larger core surface area are required, then do not usethe jumper connections but make the connections between the AC input and/or AC output terminal instead.Alternatively, make these connections external from the isolation transformer.3.3. Connecting AC input and AC outputShock hazard. Do not work on the isolation transformer or the electrical system if still connected to anelectrical power source.Connection sequence:1.Pass the AC cables through the cable glands at the bottom of the cabinet in the following way:a.Pass the AC input (shore power) cable through the left side cable gland.b.Pass the AC output (AC loads) cable through the right side cable gland.2.Connect the AC input cable to the INPUT terminal block in the following way:a.Connect the earth wire to the PE terminal.b.Connect the neutral wire to the N terminal.c.Connect the phase wire to the L terminal.3.Connect the AC output cable to the OUTPUT terminal block in the following way:a.Connect the earth wire to the PE terminal.b.Connect the neutral wire to the N terminal.c.Connect the phase wire to the L terminal.4.Connect the enclosure to the ground (=all the metal parts in the vessel) in the following way:a.Connect the M6 bolt underneath the enclosure to the vessel ground. See the below drawing for the location of the chassisearth bolt.Location of the chassis earth bolt.3.4. AC output neutral to earth linkA GFCI must be installed in the AC output of the isolation transformer. For the GFCI to operate correctly, the AC output neutral must be connected to the AC output earth and ground (= all the metal parts in the vessel).To link the AC output neutral (N) to earth (PE), place a green/yellow jumper wire (included) between male spade connectors J5 and J7.AC output neutral (N) to earth (PE) link.3.5. Cable cross-section requirementsUse the following minimal cable cross-sections:3.6. Wiring exampleWiring example isolation transformer installed on a vessel connected to shore power.3.7. Linking input and output earth when the vessel is out of the water.For safety reasons, when the vessel is out of the water (on land) during winter or for maintenance, the vessel earth (PE) conductor must be connected directly to the shore power earth (PE) conductor.This can be achieved inside the isolation transformer by connecting the yellow/green jumper wire (included) between the male spade connectors J12 and J9, as indicated below.AC input earth is connected to AC output earth when the vessel is out of the water (on land) during winter or for maintenance.Check the input and output voltage configuration before operating the isolation transformer.4.1. Inrush current limiterThe inrush current limiter prevents upstream circuit breakers from tripping when switching on the isolation transformer.4.2. Temperature protectionThe isolation transformer is fan cooled. The fan speed is temperature-controlled. Its speed (rpm) will increase if the temperature increases.The isolation transformer is protected against overtemperature and will switch off in case of overheating.。

La temperatura de almacenamiento debe estar entre -20 °C y 60 °C.El transformador de aislamiento elimina la continuidad eléctrica entre la alimentación del puerto y la embarcación. Es fundamental para la seguridad y elimina la necesidad de aislamiento galvánico y alarmas de polaridad.2.1. Seguridad eléctricaLa seguridad eléctrica se da por garantizada en las instalaciones estándares de los puertos. Saltará un disyuntor o un interruptor de circuito de fallo de puesta a tierra (GFCI) en caso de cortocircuito o fugas de corriente a la conexión a tierra. Al conectarel cable de conexión a tierra de la alimentación del puerto a las partes metálicas de la embarcación, se producirá corrosióngalvánica.Pero llevar solo los cables con corriente y neutro a bordo genera una situación insegura porque los interruptores de circuito de fallo de puesta a tierra (GFCI) no funcionarán y tampoco saltará el disyuntor en caso de cortocircuito en alguna parte metálica de la embarcación.2.2. Prevención de la corrosión galvánicaLa corrosión galvánica se produce cuando dos metales distintos en contacto eléctrico se exponen simultáneamente a un líquido conductor de electricidad. El agua de mar y, en menor medida, el agua dulce, son líquidos de este tipo. En general, la aleaciónmás activa de los dos se corroe antes, mientras que el material menos activo (más noble) tiene protección catódica. El gradode corrosión galvánica depende de diferentes variables, como la relación de áreas, la conductividad del fluido, la temperatura, la naturaleza de los materiales, etc.Se cree erróneamente que solo los cascos de metal y aluminio sufren corrosión galvánica. De hecho, puede darse en cualquier embarcación en el momento en que una pieza metálica (el eje y la hélice) entra en contacto con el agua. La corrosión galvánica disolverá rápidamente los ánodos de sacrificio y atacará el eje, la hélice y otras partes metálicas que estén en contacto conel agua cuando el barco esté conectado a la alimentación del puerto. Puede resultar tentador no conectar el conductor de conexión a tierra, pero esto es extremadamente peligroso porque los interruptores de circuito de fallo de puesta a tierra (GFCI) no funcionarán, y tampoco saltará el disyuntor en caso de cortocircuito en alguna parte metálica de la embarcación.Lo mejor para evitar la corrosión galvánica y, al mismo tiempo, evitar cualquier situación de inseguridad, es instalar un transformador de aislamiento para conectarse a la alimentación del puerto. El transformador de aislamiento elimina la continuidad eléctrica entre la alimentación del puerto y la embarcación. La alimentación del puerto se conecta a la parte primaria del transformador y la embarcación se conecta a la secundaria. El transformador de aislamiento aísla completamente el barco de la conexión a tierra del puerto. Al conectar todas las partes metálicas a la salida neutra de la parte secundaria del transformador, en caso de cortocircuito, saltará un interruptor de circuito de fallo de puesta a tierra (GFCI) o un disyuntor.La conexión a tierra del puerto conectada alos metales sumergidos del barco producecorrosión galvánica.La conexión a tierra del puerto está aislada de laconexión a tierra del barco, de modo que la corrosióngalvánica que se origina en la conexión al puerto quedabloqueada.2.3. Conversión de tensionesEl transformador de aislamiento convierte la tensión de entrada con una ratio de 1:1,05. La ratio de 1:1,05 del transformador incrementa un 5 % la tensión de salida del transformador de aislamiento. De este modo se compensan las caídas de tensión de la alimentación del puerto que se producen con frecuencia en los puertos.•Una entrada de 230 V se convierte en 240 V.El transformador de aislamiento puede usarse en sistemas de 50 Hz o 60 Hz. Sin embargo, el transformador de aislamiento no puede convertir frecuencias de 50 Hz a 60 Hz ni al revés.2.4. SoftStart (arranque suave)El arranque suave es una característica estándar de los transformadores de aislamiento de Victron Energy. Evitará que el disyuntor de la alimentación del puerto salte debido a la corriente de irrupción del transformador.2.5. Diagrama de cableado internoDiagrama de cableado interno del transformador de aislamiento.Identificación ABCDEFG2.6. Seguridad cuando el barco está fuera del aguaSe recomienda, para que las condiciones de seguridad sean óptimas, conectar la puesta a tierra del puerto a la del barco cuando el barco esté fuera del agua, durante el invierno o por tareas de mantenimiento. El transformador de aislamiento cuenta con una instalación para ello.3.1. ¿Qué hay en la caja?El transformador de aislamiento se entrega con los siguientes artículos:3.2. Descripción de las conexionesLos cables de enlace de puesta a tierra usados en los puntos 2 y 4 se incluyen con el transformador. Tienen un núcleo con una sección de 6 mm² (10 AWG) y están unidos a un conector Faston de 6.3 mm. En función de la normativa eléctrica local, esta sección de cable puede no ser lo suficientemente grande para llevar las posibles corrientes de fallo del sistema CA en el que se usa el transformador de aislamiento. Si se necesitan cables con una sección de núcleo mayor, no use las conexiones puente y haga las conexionesentre la entrada CA y/o la salida CA. Otra opción es hacer estas conexiones de forma externa con respecto al transformador de aislamiento.3.3. Conexión de entrada y salida de CAPeligro de descarga eléctrica. No trabaje en el transformador de aislamiento o en el sistema eléctrico estandoconectado a una fuente de energía eléctrica.Secuencia de conexión:1.Pase los cables CA a través de los pasacables de la parte inferior del armario del siguiente modo:a.Pase el cable de entrada de CA (alimentación del puerto) a través del casquillo pasacables de la izquierda.b.Pase el cable de salida de CA (cargas CA) a través del casquillo pasacables de la derecha.2.Conecte el cable de entrada CA al bloque terminal INPUT (entrada) del siguiente modo:a.Conecte el cable de puesta a tierra al terminal PE.b.Conecte el cable neutro al terminal N.c.Conecte el cable de fase al terminal L.3.Conecte el cable de salida CA al bloque terminal OUTPUT (salida) del siguiente modo:a.Conecte el cable de puesta a tierra al terminal PE.b.Conecte el cable neutro al terminal N.c.Conecte el cable de fase al terminal L.4.Conecte la carcasa a tierra (= todas las partes metálicas del barco) del siguiente modo:.a.Conecte el perno M6 de la parte inferior de la carcasa a la conexión a tierra del barco.

IntroductionDAC-80 is designed to remove hum and buzz created by ground loops. Normal voltage differences in the system grounding points between different pieces of equipment cause small AC power currents to flow in the shield of audio cables. Capacitance between a power transformer’s primary and secondary windings introduce signals to the circuit ground which will also create small current flows in the cable shield. Either of these problems will create hum in audio signals. DAC-80 breaks the inter-equipment ground path and greatly increases the rejection in the input circuits while remaining transparent to the audio signal. Features•Easy to use•Eliminate audio noise caused by ground loops•Designed for low signal loss and low distortion•Passive device (No power required)System Diagram2.

3B O D-□额定容量：VA单相环形变压器44.1 变压器主要技术参数：4.1.1 额定容量：30VA～3000VA4.1.2 额定频率：50Hz/60Hz4.1.3 额定电源电压：220V或其它4.1.4 额定输出电压：12V、24V、36V、220V或其它备注：(1)所列的额定电压和额定输出电压，均为独立输入、输出电压。
(2)除上述以外的电压，由用户与制造厂协商确定。
4.2 变压器绕组型式4.2.1 变压器按其容量、电压的不同分成各种不同的规格，但均为单相多绕组、初次级互耦分开绕制的变压器。
4.2.2 本系列变压器的线圈，当初次级只有一个绕组时，可担负全部额定的容量；若有多个绕组时，则按各绕组应能承担负载的容量分配；但各绕组的容量之和不得超过总容量，见图1、图2、图3、图4。
4.2.3 现举例说明：4.2.3.1 例如图1，BOD-50型容量50VA，输入电压380 V，输出电压36V。
因为初、次级只有一个绕组，所以它可以担负全部容量50VA。
4.2.3.2 例如图2，BOD-200型，容量200VA，输入电压380V，输出电压36V150VA和24V50VA。
因为图中初级只有一个绕组，所以它所承担的容量是额定容量200VA，次级有两个分开的单独绕组，而且各绕组容量已标明，所以它们各自承担容量，但总量之和200VA。
