Vitrek 950i, TTi
Faster hipot testing with enhanced safety

The new Vitrek 950i Series of hipot (high-potential) testers incorporates advanced DSP technology to enhance the speed of testing as well as adding a number of 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(TM) (safety fault interrupt), which shuts down output in as little as 50 µs from detection; and TLSS(TM) (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 50 mA of current sourcing for AC and DC hipot testing. The 200 mA 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(R) microprocessors combined with dual DSPs to provide ramp rates of up to 50 kV/s, dwell times as low as 20 ms and overall test times as fast as 3 ms in optional flash mode are achieved.
Vitrek has also added a 4-wire milliohmmeter which provides fast, accurate 5-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 100 mA to 40 A RMS and test times from 20 ms to 1000 sec or longer.
Standard interfaces include LAN/Ethernet, USB print, RS232, digital I/O and scanner control provide the highest level of test automation.
