95X Series Hipot Testers

More Speed, More Power, Better Resolution, More Functionality

For Demanding Hipot Tests
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 rock-solid resolution down to 100 pico-amps. This high resolution provides built-in insulation resistance measurement (IR) up to a Tera-ohm, add a 4-wire milli-ohmmeter with auto ranging 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 can 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.

4700 Precision High Voltage Meter

The Vitrek 4700 Precision High Voltage Meter is the top choice when you require high voltage test equipment, the 4700 offers the highest level of measurement accuracy, yet is surprisingly easy to use. Vitrek has harnessed DSP technology to provide outstanding AC & DC voltage accuracy, stability and resolution. Performance that rivals traditional HV reference dividers, yet unlike the delicate HV divider, the 4700 provides instant, direct, high voltage measurements in a highly portable, compact and rugged bench top enclosure.

4700-chart-mode-screen
The 4700’s large, high resolution, colour, touch graphic display simultaneously shows the AC and DC content of the voltage being measured and can plot readings from a few seconds to several days.

Direct Measurement or HV SmartProbe™
Vitrek’s 4700 precisely measures voltages directly up to 10KV – with no external probes. That’s high enough for most of the HV sources out there. However, should you care to expand your high voltage measurement range – just add one or more of the available 35KV, 70KV, 100KV and 150KV SmartProbes™. The Vitrek SmartProbes™ each store their own calibration data which is downloaded when they are plugged in to the 4700 – this results in high accuracy, calibrated readings and allows any Vitrek SmartProbe™ to be used with any 4700 High Voltage Meter. The SmartProbe’s™ proprietary, ultra-low TC attenuator design minimizes self-heating – while its lower capacitance construction technology enhances AC performance. In addition to the direct input terminal the 4700 has two probe inputs – use one probe to extend your measurement range or use two probes for making high voltage differential measurements.

Superior High Voltage Measurement Equipment
To ensure the best possible measurement accuracy, the 4700 makes over 40,000 reading per second which are then filtered, sub-sampled, scaled and offset corrected – all with “error free” mathematic methodology. The True RMS AC readings are as true as they come, while the DC measurements offer rocket fast settling with rock solid stability. In addition to this, the 4700 provides VLF AC readings down to 0.01 Hz, as well as peak to peak, crest factor and fundamental frequency measurement. Available G series probes offer extremely high input impedance options for electrostatic voltmeter applications.

High Voltage Test Automation
With Vitrek’s high voltage test automation feature, you can automate your HV test requirement with the 4700’s built-in Ethernet port, high speed serial communication port or available GPIB. The 4700 is fully programmable – so you can select your measurement mode and bandwidth, then take readings as often as desired. The 4700 high voltage tester also comes standard with a USB printer port, to capture readings and get hardcopy printouts of HV plots – so you can document the sag or overshoot in a typical Hipot test.

Available ISO 17025 Accredited Calibration
The 4700 and probes come with an ISO 17025 accredited calibration certificate with data at no charge. Vitrek is accredited to ISO 17025 by A2LA.
