Unmatched performance and reliabilityBypass isolation ATS Eaton’s bypass isolation automatic transfer switch (ATS) is designed to provide unmatched performance, reliability and versatility for critical standby power applications. Supervisory intelligence is provided by an ATC-900 or ATC-300+ controller, delivering operational simplicity and field adaptability coupled with diagnostic and troubleshooting capabilities. The bypass isolation ATS design is ideal for those applications where the ability to perform maintenance is required without interrupting power to life safety and other critical loads.Product configuration• Automatic operation—ATS and bypass switch• Open and closed transition• 100–1200 A rating• Two-, three- or four-pole• NEMA T 1, 3R• Up to 600 Vac, three- orfour-wire, 60 Hz or 50/60 Hz• Drawout ATS and fixedbypass switch, facilitatingconcurrent maintenance• Service entranceFeatures and benefitsProven performanceand reliability• Automatic and non-automaticoperation modes are availableto provide multiple methods oftransferring the load betweenpower sources• Manual operation allowsunloaded transfer betweenpower sources for allproduct configurations• UL T 1008 Listed short-circuitand short-time (select catalognumbers only) withstandclosing current ratingsmaximize system reliabilitySimplified installationand integration• Factory-configured powersource and load terminalsfor top/bottom cable ingress• Removable enclosure panelsprovide front and rear accessto cable terminal connections• Seismic certified to OSHPD,CBC, IBC and UBCEnhanced safety• Two-door, compartmentalizedconstruction provides steelbarriers, protecting workers• Integral safety interlocksautomatically open the maincontacts prior to the ATSbeing isolated for test orremoved for serviceImproved serviceability• Two-door design eliminatesthe need to scheduleshutdowns for routine test,inspection or maintenanceof the ATS• Drawout design allows theATS to be disconnectedfrom the electrical bus andisolated in cell for regulartesting as prescribed bycode (NFPA T 70, 99, 110)• Testing of the isolated ATScan be performed whilethe bypass switch is in theautomatic or non-automaticmode of operationDesign featuresDual automatic technology Eaton’s bypass isolationtransfer switch design includes an automatic bypass switch and an ATS housed within a single assembly.Regardless of which power switch is actively distributing power, redundant automatic operation provides for a rapid load transfer and restoration of power to life safety and critical loads, eliminating the need for active supervision by qualified personnel.Segmented construction The ATS and automatic bypass switch are housed in separate compartments, with robust steel walls, that isolate the power switches from each other to facilitate ease of maintenance and worker safety. Eachcompartment includes a door with padlockable handle. This design prevents the possibility of inadvertent contact andunnecessary exposure to power cable terminations and energized electrical control components.Drawout ATS and fixed-mounted bypassService personnel can rack-out and isolate the ATS (with compartment door closed) from the electrical bus for routine test or exercise. A Kirk T -key interlock prevents access to the racking mechanism until the load connection has been transitioned to the automatic bypass switch.Opening the compartment door allows the ATS to be completely drawn out of the cell for inspection or maintenance.Safety interlocks prevent rack-out or rack-in of the ATS from the electrical bus with the main contacts closed. The automatic bypass switch is fixed mounted to the electrical bus and stands ready to initiate an automatic load transfer when the ATS is undergoing maintenance.Multi-tap control power transformerSystem voltage can be fieldconfigured via a multi-tap control power transformer (CPT) with quick-disconnect plugs.T ransition to bypass mode When maintenance or testing of the ATS needs to be performed, qualified personnel can easily and quickly transition the load connection between the ATS and automatic bypass switch using door-mounted operator controls fitted with indication lights. The transition occurs in a make-before-break fashion, ensuring continuous power flow to loads.Multiple operation modes Operation is possible in the following modes:• Automatic • Non-automatic •Manual AIn automatic mode, the transfer switch is self-acting, and atransfer is automatically initiated by the intelligent logic controller.In non-automatic mode(optional), a transfer is initiated by the operator using a door-mounted selector switch.In manual mode, a transfer is initiated by the operator using controls mounted directly on the automatic bypass switch or ATS.Alternatively, a transfer can be initiated remotely via an HMi remote annunciator controller.A Manual operation (unloaded) is provided forall product configurations.for top and bottom cable terminationFixed-mounted automatic Drawout ATS can be isolated for test within compartment orand automatic bypassswitch compartments600–1200 A rating (480 V), NEMA 1 enclosure100–400 A rating (480 V), NEMA 1 enclosureFixed-mounted automatic Drawout ATS can within compartmentor completely removedRemoveable optionpanels allow front access for top and bottom cableterminationDrawout ATS removed for bench level inspection/Automatic bypass switch stands ready to transfer load2EATON Bypass isolation automatic transfer switchesStandard enclosure dimensions and weightsDimensions and weights shown are approximate and subject to change.

由于发光二极管的内阻非常小只有几百欧姆, 而干扰源的内阻一般很大, 在发光二极管上得到的干扰电压是非常小的, 因此, 大大削弱了其的强度, 同时由于发光二极管必须有足够的电压和电流时才能发光, 尽管干扰信号的电压很高, 但其电流很小, 能量则很小, 因此, 它不足以驱动发光二极管发光, 在光电隔离器的另一端就不会有干扰电压输出, 下图是光隔前后的信号波形图:在光隔前还能够增加一级滤波器用以消除高频干扰, 常见的滤波器有RC、巴特沃斯、切比雪夫等。
其中RC无源滤波器是最经济实用的, 实践证明, 在光隔前加上一级RC滤波器就能够很好的完成滤波任务, 当然, 如果能加上其它有源滤波最好了, 它们能够提供更加锐减的频率截止特性。

model 251光隔离型接口转换器说明书
Model 251RS-232/RS-485光电隔离接口转换器用户手册1.0 概述Model 251是一种RTS控制发送的光电隔离的RS-232到RS-485接口转换器。
Model 251能够将RS-232的TXD和RXD信号转换成平衡的半双工的RS-485信号。
在RS-485一侧，Model 251是通过一个外部的+9VDC@200mA的交流/直流电源适配器来供电的。
在RS-232一侧，Model 251是通过20针(DTR)和4针(RTS)的控制信号线来供电的。
DTR必需一直设成高电平。
RTS必需在高电平(发送时)和低电平(接收时)之间切换，这样Model 251才能正常工作。
由于Model 251在RS-232接口一侧需要DTR供电并用RTS来控制发送/接收，所以对有些接口和软件并不适用，用户在感觉不方便时可以选用其它型号，如FC-485S或FC-485SI+等。
2.0 性能参数2.1 接口兼容EIA的RS-232和RS-485标准2.2 连接器和信号Model 251型转换器采用一个DB25型的母(孔)连接器与RS-232接口相连,另一端采用4位接线端子连接器与RS-485接口相连.同时提供一个金属连接器用来接地。

Thisstandard feature allows the user the ability to withdraw, maintain or swap the assemblies. Selective coordination The Magnum bypass isolation switch is ideal for emergency, legally required standby systems or other criticaloperations requiring selective coordination. Magnum bypass switches up to 4000A are UL 1008 listed for 85 kAwithstand rating for 30 cycles. Fast transfer timeThe Magnum transfer switch uses a high-speed transfer mechanism allowing open in-phase transfer on large ratings. This feature is factory selectable to be open in-phase transfer with a default to load voltage decay or a default to time delay neutral. The Magnum comes standard with a delayed transition.Integrated service entrance ratingThe factory addition of anoptional overcurrent trip to the power case switch enables the bypass unit to be rated as a service entrance bypass isolation ATS. Selection of the overcurrent trip can be made from the series of Eaton Digitrip™ RMS trip units including the standard Digitrip 520 or optional 520M, 520MC or Digitrip 1150.Arcfl ash Reduction Maintenance System™The switch can be supplied with the optional ArcflashReduction Maintenance System maintenance mode function with the selection of the Digitrip RMS 520MC or 1150 trip units. This feature will reduce arc flash incident energy that is generated on a fault condition.Multi-tap voltage selector Allows the transfer switch to be readily applied on most system voltages worldwide by connecting to the proper terminals. Available system voltages include 120, 208, 220, 230, 240, 380, 401, 415, 480 or 600 Vac, 50 or 60 Hz.Contact wear indication All Magnum switches include a contact wear indicator. The contact wear indicator is viewed by removing the arc chutes and shows if the contacts are good or if there is wear indicated.ATC-900 controllerEaton’s new ATC-900 controller brings ease of use, adaptability, supervisory and programming capabilities to mission-critical applications. The 4.3-inch color TFT display provides simple arrow keys for quick screen navigation. Event logging and recording of time-stamped events are easily viewed. Field configuration of I/O allows user adaptability to special requirements.2EATON Automatic transfer switchesMagnum bypass isolation drawout transfer switches200–3200A Drawout NEMA 1200–3200A Drawout NEMA 3R(Controller and Device Panels Mounted on Inner Door)4000–5000A Drawout NEMA 13EATON Automatic transfer switchesEaton is a registered trademark.All other trademarks are property of their respective owners.Eaton1000 Eaton Boulevard Cleveland, OH 44122United States © 2014 EatonAll Rights Reserved Printed in USAPublication No. PA140001EN / Z14948March 2014Automatic Bypass Isolation Magnum-Based T ransfer Switch Catalog Numbering SystemBypass Isolation DiagramT ypical Bypass Isolation Switch SchematicSystem Coordination Information—Withstand, Closing and A Ratings used for coordination with upstream breakers with short-time ratings.B UL 1066 short-time withstand rating.Fully rated fourth pole (switched neutral)Eaton provides a fully rated switched neutral or fourth pole, meaning that the fourth pole has withstand, interrupt and closing ratings identical to the power contacts. The neutral pole is operated on a common shaft with the power contacts, thereby ensuring simultaneous opening and closing of the switched neutral. Eaton’s fully rated fourth pole eliminates typical problems with a three-pole overlapping neutral:•Eliminates nuisance ground trips at the main due to circulating zero sequence harmonic current between sources•Reduction in ground current due to isolated single ground point lowers arc-flash levels and reduces generator damage•Eliminates potential for faults to propagate across overlapping neutral; fully rated fourth pole will handle as a normal operation •Does not generate voltages that exceed normal phase voltageotee:N For more detail, reference Eaton white paper Three- and Four-Pole Transfer Switching Characteristics , IA08700002E.。
