模型19032 19032-P电子安全分析仪功能特性说明书

General Electrical Safety Testing SolutionElectrical safety testing is one of the major itemsin the electrical product quality tests. All electricalproducts consisting of adapter, SMPS, charger,house appliance, information technology productand video products are required to performelectrical safety test.The 19032 series combines Hipot, InsulationResistance( IR), Ground Bond (GB), LeakageCurrent (LC)/AC LC/DC LC and Dynamic FunctionTest. Savings can be up to 50% of productionline space, by not purchasing several safetytest instruments. The 19032 is able to increaseefficienc y of electrical safety test duringmanufacturing and reduce the labor cost on thesetest.Open/Short Check (OSC)Patent No. : 254135All manufacturers have to solve the problems oferror connections and unconnected test cableswith their production line testers. Chroma's 19032is equipped with an open/short check function(OSC) for product testing. This eliminates thepotential for false failures.Twinport TM FunctionUSA Patent No.: US6504381The key factor affecting the efficienc y ofmanufacturing is the efficiency for electrical safetytest. The Twinport function reduces the safety testtime and can eliminate potential bottlenecks inthe production line.Product ApplicationThe 19032 series can be applied to versatiletest of electrical products, which includequality assurance sampling inspection test,manufacturing test and development validation.• Power cord• House appliances• Information technology product• Medical equipment• Lab/testing equipment• EMI FILTER• Electric Vehicles• Solar, PV inverterEN50191 Floating Output FunctionThe leakage current of any ground terminal shouldbe lower than 3.5mA when operating Floatingoutput function. This allows the operator near theground terminal to avoid an electrical hazard. ELECTRICAL SAFETY ANALYZER MODEL 19032/19032 PPATENT NO. 254135The OSC function is used to check if the connection is open (bad contact) or short (DUT short) during the test procedure. When a circuit is open during EST testing, bad product can pass as good product. When a short occurs during testing, proper screening can reduce the damage on the DUT.DUT's have capacitive loads (Cx) from tens of pF to several uF, in a normal state. A micro capacitance will occur on an open circuit interface once the connection is interrupted (as Cc in gure 2). In general, the capacitance is lower than 10pF; thus the total capacitance is lower than normal product. The capacitance is far higher than normal when the DUT is short or close to a short. This allows users to judge the short issue by using high/low limit values of capacitance change.Manufactures apply Chroma's AC source as a power supply to increase the input voltage stability for dynamic leakage current test. The 19032 uses RS232 interface to control the AC source and allows convenience in running the leakage current test.Chroma 6400/ 6500/ 61500/ 61600 SeriesFigure 1 : Normal Leakage Current WaveformFigure 2 : Leakage Current Waveform when ashover occurredFigure 1 : Normal Connection Figure 2 : Connection OpenFigure 3 : Connection ShortUSA PATENT NO. US6504381The 19032 electrical safety tester has Twinport ™ Technology. This patent and unique feature allows both hipot and ground bond to be tested simultaneously. This is idea for production test, as it allows test time be reduced by 50%.The 19032 has Flashover Detection, as other Chroma test instruments. Flashover is electricity transient or non-sequential discharge generated by the inner or surface of insulation components, which causes DUT's to lose the original insulation feature. Electrically generated carbonation of conductive material can damage the product. Test voltages or shift rate of leakage current is required. Flashover cannot be detected by a leakage current test, which makes the Flashover Detection a valuable tool in High Voltage testing.To allow for operator safety, Chroma invented the Floating Circuit, which is based on leading technology. With Floating status, the grounding leakage current will not exceed 3.5mA, no matter what the withstand voltage is. This complies with EN50191 for outputting to ground terminal within current limit and for protecting the operator from electric shock.The High Limit of Hipot test currently ranges from 5 -10mA. However, there are other DUT's such as Safety Integrated Analyzer of EMI Filter or large motors requiring a large amount of power. The 19032-P enhances the power of the 19032 to equip the capabilities of outputting and measuring AC 100mA/DC 25mA.This is used to integrate the high charge current for other safety test, as any integrated analyzer for use with high leakage current or large-sized electrical safety equipment. This maximizes the e ciency of the production line and quality assurance.The design of the 500VA complies with the requirement of IEC/UL output power to add the selection function of no protection for trip circuit under short current 200mA and 100mA .The ultimate purpose of safety testing is to protect users for electrical hazard. The 19032-P has a GFI function to protect the operator. The GFI function can cut-o the power output immediately, while human body is experiencing electric shock. The GFI function detects the current from the Earth (operator) and LOW terminal (device). The voltage output will be cut-o , if the current is over 0.5mA.The current brimmed after ow through insulation resistance, is called Leakage Current. When the leakage current goes through the human body, the current flows to Earth via the human body. The leakage current is testing under an operating state. The human body RC network will be added to leakage current in real conditions.The leakage current has different testing modes and standards in accordance with the di erent safety test and test points. The most common test are Earth Leakage Current, Patient Leakage Current and Patient Slave Leakage Current. The 19032 is used with different dynamic leakage current modules and human body simulation, equivalent circuit for the requirements of various safety modules. It can apply to Electrical Safety Testing for Household Appliances, VideoProduct, Medical Equipment and etc.POWER SUPPLIES(SMPS), ADAPTER AND CHARGER SAFETY TESTINGInformation technology is a big part of our daily life. Desktop, notebook, LCD monitor, UPS, printer and projector are the products that we use in our everyday lives. To ensure proper safety, all products should have electrical safety test preformed. The 19032 o ers all functions of safety test and Normal/Reverse as well as Single Fault switch function (LC Test) to increase manufacturing e ciency.The output floating of Telecommunication Network in IEC 60950 to perform dynamic leakage current test is required. The equivalent stray capacitance will also be generated on an isolation transformer, even if it is a floating circuit. The stray capacitance results in leakage current and electric shock to the users. The 19032, along with the 6000-05/07/08 leakage current scanner, have P1/P2 measurement function which is able to measure dynamic leakage current on output terminals. It is the best solution for testing information technology products.MAIN TEST ITEM • Open Short Check • Ground Bond • AC/DC Hipot Test• Earth Leakage Current Test • Output Leakage Current TestPower supplies of electronic products, including SMPS, Adapter and chargers, need to preform electrical safety test. According to various power design methods and test conditions, the 19032 o ers programmable edit and solution, allowing the operator to complete all test at one time.A number of power products designs have the insulation capability of input terminal (Primary) to output terminal (Secondary) required to protect the damage inside the component. Thus, the output terminal of Floating needs to perform Hipot test. The 19032 provides an isolation test point with high voltage which allow you not to change the xture or cable manually, but perform P-S Hipot test directly after P-G Hipot test.If there is danger in making contact with the output terminal (Secondary), dynamic leakage current test also need to be performed.LED in the lighting industry is widespread and are being used in a variety of products. EachLED and power product needs to be tested for withstand voltage, insulation, groundingresistance and leakage current , for protection from personnel electric shock.Chroma19032 with 4HV/4GC ScannerVideo products include DVD recorders, LCD's, TV's, audio amplifiers, stereos and etc. These products have mass power output with separate safety standards. The main circuit design of mass power is a signal output terminal, not to mention an increase in temperature and heat dissipation of electronic component. Open voltage of some video products are over 35Vac peak or 60Vdc peak; this allows for U1 dynamic leakage current test as required. A U1 measurement circuit is added to the 19032 and P1/P2 measurement point is provided to comply with the requirement of safety standard test.MAIN TEST ITEM• Open Short Check• Ground Bond• AC/DC Hipot TestRefer to UL 60601-1 ﬁg. 18 Measuring circuit for the Enclosure Leakage CurrentHousehold appliances consist of ovens, refrigerators, televisions, juicers and coffee machines that may come in contact with a person. To ensure the safety of users, all products should preform electrical safety test. Except for the basic hipot test, dynamic leakage current has various test regulations by different ground modes and operation methods. The regulations are as listed in the table below.MAIN TEST ITEM • Open Short Check • Ground Bond • AC/DC Hipot Test• Earth Leakage Current TestThe 19032 + 6000-08 is a solution for electrical safety and function test of medical equipment. The safety standard of medical equipment is very strict. Since the medical equipment comes in contact with the patient and hospital personnel, the instrument preforms various electrical safety test. The leakage current test has become one of the most important test in preforming electrical safety test.The safety standard of medical equipment has various types of leakage current test. Also, normal/reverse/single fault normal/single fault reverse four powers and earth switch, make the safety test difficult and complex. The basic measuring circuit for the enclosure leakage current is as in the figure. It shows here measurement Type BF and CF is a special requirement for medical equipment. DC leakage current should be isolated separately and limited within 50uA limited, which is mentioned in the medical safety standard. This function has already been added to the 6000-08 LC scanner. The Chroma 19032 + 6000-08 offer programmable editing and software support. This allows you to test medical products without missing a procedure, as it saves the test data directly, providing the best test solution.MAIN TEST ITEM • Open Short Check • Ground Bond • AC/DC Hipot TestThe Automotive industry has switch focus from internal combustion engine power to electric power.
