Brand: Vitrek
Model Series: 950i Series

About Product

The Vitrek 950i Series Electrical Safety Compliance Analyzers are ultra-high performance hipot testers which combine high output power, wide range of AC & DC voltage outputs and extremely low leakage current measurement. A 4-wire Milliohmmeter with dynamic range up to 100kΩ and an overlapping Tera-ohm class Insulation Resistance function are added. The 950i Series are also available with 40 Amp Ground Bond test capability. The 6.5kV DC models offer 50mA of source current for DC hipot, providing the power needed to rapidly charge and discharge challenging DUTs. Models are also available with DC hipot up to 11kV and 15kV. Most models offer 50mA of sourcing for AC hipot, but for heavier AC loads the 950i Series can be configured to source up to 100mA or even as much as 200mA. For higher AC hipot voltages, up to 10kV can be internally generated and all models are available with an external 30kV AC hipot option. The 950i Series have the ability to directly control up to four 64-channel HV scanners and this is up to 256 test points.  With the use of Vitrek’s QuickTest Pro Software, up to 640 test points can be expanded. The Vitrek 950i Series are safety tested per EN 61010-1 and EMC Compliant to EN61326-1.

Product Functions

  • Functional capabilities of 950i Series (See photo section)
  • The 950i Series combine high output power, with a wide range of AC & DC voltage outputs and extremely low leakage current measurement, together with 40A Ground Bond capability
  • 4-wire Millohmmeter Function provides fast, accurate 5 digit resistance measurements with resolution down to 100µΩ and range up to 100kΩ
  • Built-in phase angle measurement allows the measurement and display of both resistive (in-phase) leakage current and reactive (out-of-phase) leakage current caused by capacitive coupling
  • Multi-dwell 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 permit the user to set separate limits for the ramp and dwell providing faster ramp times and lower leakage test limits
  • 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 15kV DC
