Forget what you’ve learned about typical high voltage insulation testers – Vitrek has incorporated advanced DSP technology into the new 950i series to bring you the fastest, most capable, feature rich hipot testers available for a surprisingly low price. Vitrek’s new 950i Series combines high output power, with a wide range of AC & DC voltage outputs and extremely low leakage current measurement. Then we added a 4-wire milli-ohmmeter with dynamic range up to 100K ohms and an overlapping Tera-ohm class Insulation Resistance function. Top that off with an available 40 Amp Ground Bond capability and you’re just beginning to get a feel for what the new Vitrek 950i Series Hipot Testers can do for you. Choose form the 951i, 952i, 953i, 954i, 955i or the Ground Bond only 959i. * International prices are approximately 5% higher than those listed below.

Features & Benefits:

Highest Level of Operator Safety - features include: HSSD™ High Speed Solid-State load Discharge -to remove exposed voltages faster than passive resistor designs, SFI™ Safety Fault Interrupt - shuts down output in as little as 50uS from detection, TLSS™ Test Lead Safety Sense - continuously verifies that test leads are properly connected prior to and during HV and continuity testing, Recessed start switch prevents inadvertent actuation, Dual Channel current measurement detects earth leakage faults
High Power Output- means better drive capability and increased test throughout. With up to 50mA of current sourcing for AC & DC hipot the 950i Series gets heavy duty jobs done fast - available 200mA drive tackles even tougher sourcing requirements
Wide Range of built-in Voltage Capabilities - starting at 6KV AC/DC extending to 10KVAC and 11KVDC or up to 30KV RMS AC with external option
The Fastest Hipot Testers available - Thanks to our Dual Coldfire® microprocessors combined with Dual DSPs to provide Ramp rates up to 50KV/second, dwell times as low as 20mS and overall test times as fast as 3mS in optional Flash mode
Expansive Test Sequence Memory holds up to 100 tests with up to 100 steps per test. Tests can be selected via front panel, RS232 or Digital I/O or with optional GPIB/Ethernet
