95x Series Hipot Tester Product Overview
Power & Versatility for your Most Demanding Electrical Safety Test Applications
Vitrek built the 95X Series from the ground up with DSP technology – to bring you the safest, fastest, most capable, feature rich hipot testers available. The 95X Series combines high output power, with a wide range of AC & DC voltage outputs and extremely low leakage current measurement. Then we added a 4wire milliohmmeter with dynamic range up to 100K ohms and an overlapping Teraohm 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 Vitrek 95X Series Hipot Testers can do for you.
More Speed, More Power, Better Resolution, More Functionality
What more could you want in an Electrical Safety Tester?
Vitrek 95X Series Hipot Testers
For more than 25 years Vitrek has been driven by an obsession to build a better hipot tester. Increased user safety, faster test times, higher output voltages and more functionality have been our driving force. The 95X series is the result of this pursuit – offering power, speed, accuracy and resolution that leave the others far behind.
For Demanding Hipot Tests – Demand the Vitrek 95X
Speed and power go hand in hand, the 6.5KVDC models offer 50mA of source current for DC Hipot – providing the power you need to rapidly charge and discharge challenging DUTs. Models are also available with DC hipot up to 11KV and 15KV. Most of the 95x series also offer 50mA of sourcing for AC hipot, but for heavier AC loads the 95X can be configured to source up to 100mA or even as much as 200mA. For higher AC hipot voltages the 95X can generate up to 10KV internally and all models are available with an external 30KVAC hipot option.
When it comes to making critical leakage current measurements, the 95X delivers rocksolid resolution down to 100 picoamps. This high resolution provides builtin insulation resistance measurement (IR) up to a Teraohm, add a 4wire milliohmmeter with autoranging up to 100K ohm and an available 40 amp Ground Bond function – and you are beginning to understand the versatility of the Vitrek 95X Series.
Need To Hipot Multiple Test Points?
The 95X has the ability to directly control up to four 64 channel HV scanners, right out of the box. That is up to 256 test points and using a PC with Vitrek’s QuickTest Pro software you can expand the count up to 640 test points. The HV Switching System of choice is the Vitrek 964i which can hold eight 8 channel switching cards – available in 7, 10 & 15 KV ratings. The 964i also has switching cards to handle routing up to 40 amp ground bond currents.
95x Series Hipot Tester Features
Product Features and Benefits
 Highest Level of Operator Safety – features include: GFI High speed shut down for earth ground leakage faults, SFI™ Safety Fault Interlock – High speed shut down output for interruption of safety interlock, TLSS™ Test Lead Safety Sense – Clamps DUT chassis near ground by continuously verifying proper connection of test leads prior to and during HV testing, Recessed start switch prevents inadvertent actuation
 High Power Output – means better drive capability and increased test throughout. With up to 50mA of sourcing current for DC hipot the 95X Series gets heavy duty jobs done fast – available 100mA & 200mA AC drive tackles even the toughest sourcing requirements
 Wide Range of builtin Voltage Capabilities – Choose from 6.5KVDC, 11KVDC or 15KVDC and 6KVAC, 10KVAC 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, Ethernet, RS232, Digital I/O or with optional GPIB
 Ground Bond Test Capability available in three models with output currents from 100mA to 40Amps RMS and test times from 20mS to 1000 seconds or longer

4Wire MilliOhmmeter Function provides fast, accurate 5 digit resistance measurements with resolution down to 100µΩ and range up to 100K ohm

Builtin Phase Angle Measurement – allows the measurement and display of both resistive (inphase) leakage current and reactive (outofphase) leakage current caused by capacitive coupling

MultiDwell Functionality – permits dwells at different voltage levels without having to return to zero between test steps – dramatically simplifying advanced analysis of dielectric properties

Ramp High/Dwell Low Current Limits – permits the user to set separate limits for the ramp and dwell providing faster ramp times and lower leakage test limits

Ethernet, RS232, Digital I/O, USB Printer & Scanner Control – All Standard Interfaces – Provides the highest level of test automation. GPIB optional

High Voltage Scanner Control – up to 256 point switching capability with available 964i HV Scanners. Route voltages up to 15KV and currents up to 40A for multipoint hipot and ground bond tests

Dual Dimensional / Test Specific / Broadband Arc Detection. Where lesser testers allow you to set a single, global, amplitude only arc limit – the technologically advanced 95X Series utilizes time & amplitude based arc limits and uniquely applies them to each desired test

PicoAmp Leakage Measurement insures that even the lowest leakage current levels are accurately detected and teraohm range IR readings are stable and precise

Test Specific Fixture & Cable Compensation – Automatically calibrate out offset errors caused by lead resistance, fixture capacitance and leakage

MultiMode IR – Insulation Resistance values up to one Teraohm can be obtained with precision in your choice of 3 IR test modes – end on time, end on pass or end on fail

Continuously Variable IR Test Voltage – Unlike most IR testers which limit you to 3 or 4 discrete test voltages, the 950i Series allows you to select the test voltage you need. Starting as low as 20V all the way to 6.5KV, 11KV or 15KVDC

Capacitance Test Modes – For AC & DC hipot and IR provide tightly controlled charge and discharge profiles for superior results on critical solar panel tests and other highly capacitive loads

Light Weight Switching Power Supply Design – Better reliability, easier on your back. Compare the 8.2 kg 95X to whatever you’ve been using

400Hz AC Voltage Withstand Testing provides aviation frequency specific test results for a more effective analysis of dielectric properties on avionic components

Solar Panel Testing Simplified – Designed with PV testing in mind, the 950i Series uses picoamp resolution to detect minute defects in solar cells

3 Year Extended Warranty – 1 year standard, total of 3 years extended warranty with registration and annual factory calibration. Builtin reliability you can count on for years to come
