High-potential testers are faster and safer
TTid is introducing the Vitrek 950i Series hipot (high-potential) testers that incorporate advanced DSP technology to enhance the speed of testing as well as adding new capabilities.
A high level of operator safety is ensured by a number of new features including: HSSD (high-speed solid-state load discharge), which removes exposed voltages faster than passive resistor designs; SFI (safety fault interrupt), which shuts down output in as little as 50us from detection; and TLSS (test lead safety sense), which continuously verifies that test leads are properly connected prior to and during high-voltage and continuity testing.
The 950i Series combines high output power with up to 50mA of current sourcing for AC and DC hipot testing. The 200mA drive tackles even tougher sourcing requirements with a wide range of AC and DC voltage outputs and extremely low leakage current measurement. Thanks to the dual Coldfire microprocessors combined with dual DSPs to provide ramp rates of up to 50kV/s, dwell times as low as 20ms and overall test times as fast as 3ms in optional flash mode are achieved.
Vitrek has also added a four-wire milliohmmeter that provides fast, accurate five-digit resistance measurements with resolution down to 100 microhm and range up to 100 kilohm with an overlapping tera-ohm class.
Ground bond test capability is available in three models with output currents from 100mA to 40A RMS and test times from 20ms to 1000s or longer.
Standard interfaces include LAN/Ethernet, USB print, RS232, digital I/O and scanner control provide the highest level of test automation.
The Vitrek range is available exclusively in the UK from TTid. Follow the link for more information about the Vitrek 950i Series hipot testers.
