The 19032 series combines Hi-Pot, IR, GB, LC/ALC/DLC and Dynamic Function Test. The 19032 can reduce the space waste for 50% on manufacturing thus purchase more than one Hi-Pot tester isn't required. However, the 19032 be able to promote the efficiency of electrical safety testing on manufacturing in order to reduce risk on testing.
All manufacturers have to solve the issues of error connection and test cable unconnected. Chroma's 19032 is equipped with up-to-date open/short check function (OSC) for products testing.
The key factor affects the efficiency of manufacturing is the efficiency for electrical safety testing. Twinport function can lower the time of safety test, the safety workstation won't be a bottleneck in production line any longer.
The 19032 can apply to versatile tests of electrical products includes quality assurance sampling inspection test, manufacturing test and development validation.
In digital time, information technology is close to our life. Desktop, notebook, LCD monitor, UPS, printer and projector that human may contact at any time. For ensure the safety of users, all products should do electrical safety testing. The 19032 offers all functions of safety test and Normal/Reverse as well as Single Fault switch function (LC Test) to reduce the load of manufacturing personnel.
Besides, 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 isolated transformer even it is Floating circuit. The stray capacitance results in leakage current, electrical hurt to users. The 19032 along with 6000-05 /07/08 leakage current scanner have P1/P2 measurement function which be able to measure dynamic leakage current on output terminal. It is the best solution for your testing on information technology product.
Power supply of electronic products are inclusive of SMPS, Adapter and charger that need to perform electrical safety test. According to various power design methods and test conditions, the 19032 offers programmable edit and solution to let you complete all tests at one time.
A lot of designs of power product, the insulation capability of input terminal (Primary) to output terminal (Secondary) is required to protect the damage inside component. Thus, the output terminal of Floating needs to perform Hipot test. The 19032 provides isolation test point with high voltage to let you no need to change fixture or cable by manually that performs P-S Hipot test directly after P-G Hipot test.
Moreover, if there is the danger can be touched at output terminal (Secondary), dynamic leakage current test also need to be performed.
Video products are inclusive of DVD recorder, LCD TV, audio amplifier, stereo and etc. These products have mass power output thus separately safety standards shared. The mainly circuit design of mass power is signal output terminal except temperature increasing and heat dissipation of electronic component. Open voltage of some video products are over 35Vac peak or 60Vdc peak that performs U1 dynamic leakage current test is required. U1 measurement circuit is added to the 19032 and P1/P2 measurement point provided that comply with the requirement of safety standard test.
House appliance consists of oven, refrigerator, television, juicer and coffee machine that human may contact at any time. For ensure the safety of users, all products should do electrical safety testing. Except basic Hipot test, dynamic leakage current has various test regulations by different ground mode and operation method. About the regulations are as below table shown.
Main Test Item
19032 + 6000-07 is a solution for electrical safety and function test of medical equipment. The safety standard of medical equipment is very strict. Because the medical equipment keeps in touch with the health of the doctor and patient frequently, make several electrical safety tests can't be ignored especially leakage current test which has already become the most important test in electrical safety test.
The safety standard of medical equipment has various of leakage current tests. Additionally, normal/reverse/single fault normal/single fault reverse four powers and earth switch, let medical equipment safety test difficulty and complexity further. The basic measuring circuit for the enclosure leakage current as below figure. In addition to measuring Type BF and CF is a special requirement for medical equipment. DC leakage current should be isolated separately and within 50uA limited which mentioned in medical safety standard. The function has already been added to the 6000-08 LC scanner.
Chroma's 19032 + 6000-07/08 offer programmed edit and software support, let your test procedure of medical product not missing which save the test data directly to provide you the best test solution.
Main Test Item
The 19032 series electrical safety tester has our patented Twinport™ Technology. This patented and unique feature allows testing both a Hi-pot test and a ground bond test simultaneously, it can cut the test time in half and is ideal for production testing.
The 19032 has Flashover Detection as other Chroma safety test series. Flashover is electricity transient or non-sequential discharge on inner or surface of insulation component which cause DUTs the original insulation feature loss, carbonation electrically conductive path generated and product damaged. Flashover can't be detected by leakage current, test voltage or shift rate of leakage current is required. Thus, Flashover Detection is one of inevitable inspection item in HV test.
OSC function is used to check the connection is open (bad contact) or short (DUT short) during the test procedure. When open occurred during test procedure, no good product will be judged as good product. When short occurred during test procedure, screening earlier to reduce the damage on equipment for saving test cost.
Generally speaking, the DUT has capacitive load (Cx) from tens to thousands pF under normal status. To form a micro capacitance on open circuit interface once connection interrupted (as Cc in figure 2). Generally speaking, the capacitance is lower than 10pF thus total capacitance is far lower than the status of normal product. The capacitance is far higher than normal status when DUT short or close to short. Therefore, users judge the short problem by using high/low limit value of capacitance change.
The manufacturers apply Chroma AC Source for power supply in order to promote input voltage stability ofdynamic leakage current test. The 19032 can use RS232 interface to control AC Source related models to let you more convenience in testing dynamic leakage current.
The ultimate purpose of safety testing is protecting users from electric hazard. The 19032-P also has GFI function to protect operator. GFI function cut off the power output immediately while human body suffering electric shock. GFI function detects the current from Earth GND (Ioperator) and LOW terminal (Idevice). The voltage output will be cut off if the current is over 0.5mA.
Chroma develops Floating circuit by all new technology in order to let operator to use safety test equipment safely. Whatever the operator touches any Hipot test terminal under Floating status. The earth leakage current is lower than 3.5mA, the operator won't be hurt by electricity.
The current brimmed after flow through insulation resistance, we called it as Leakage Current. When the leakage current contact with human body, the current flows to Earth via human body thus causes electric damage. The leakage current is testing under operating status. A human body RC network will be added in leakage current test, it can simulate the value of leakage current in real condition.
The leakage current has different test modes and standards in accordance with different safeties and test points. The most often seen current tests are Earth Leakage Current, Patient Leakage Current and Patient Slave Leakage Current.
The 19032 is used with different dynamic leakage current module and human body simulation equivalent circuit for the requirements of various safety modules. It can apply to Electrical Safety Testing of House Appliance, Video Product, Medical Equipment and etc.
The High Limit of Hipot test currently is often from 5 to 10mA. However, there is still a few of DUTs such as Safety Integrated Analyzer of EMI Filter or large-sized motor require mass power. The 19032-P promote the power of 19032 largely to let it equipped with the capabilities of outputting and measuring AC 100mA/DC 20mA.
Integrate Mass power Hipot test with other safety tests as a integrated analyzer for the users to use higher leakage current or large-sized electrical safety equipment. This brings the best efficiency to production line and quality assurance inspection.
The design of 500VA also comply with the requirement of IEC/UL output power to add the selection function of "don't be protected by trip circuit under short current 200mA and 100mA".
