Testronics Model 402HV, High Voltage
Backplane Test System
for high reliability backplane testing

Our model 402HV is the result of 25 years of high voltage / high pin count test systems experience. We produced our first high voltage system back in 1985. It was programmable up to 600 volts / 600 Mohms and had over 49,000 test points. It could test a 5k point board in less that 15 seconds. Since then we have built hundreds of high voltage test systems, with our highest voltage system capable of testing up to 2000 Volts DC / 1500 Volts AC. (One of our 600 volt systems, built in 1986 is still in operation testing boards for a defense contractor.)

Our model 402HV is our latest generation system and can be configured with a wide range of voltage capabilities. (Our latest system shipped was a 500 volt 402HV with 61,000 test points.)
