964i High Voltage Switching System for Automated Multi-Conductor & Cable Testing

The 964i is ideal for automated multi-conductor, multi-point hipot testing.

Imagine having a task to hipot test a 16-conductor medical cable at 8500V to confirm that each conductor is appropriately isolated from the others. There are two options: attempt it manually or use the Vitrek 964i multi-conductor hipot tester to automatically route the HV and return signals to the appropriate test spots.

The manual procedure is challenging, slow, error-prone, labor-intensive, and potentially dangerous to the operator. It is also not possible to record the test findings. The 964i, on the other hand, is designed to fully automate all high-voltage switching requirements.

The 964i can be paired with a Vitrek 95X Series Industrial Strength Hipot Tester and the QTPro test automation software. Such a choice can result in the company receiving the Malcolm Baldridge National Quality Award.

The 964i can accommodate up to eight eight-channel HV switching cards. This translates to up to 64 test points in a single mainframe; many units can be coupled to improve capacity.

The 964i will seamlessly route test points to the tester to connect an 8-pin connector, a 64-conductor cable, or an entire tray of SMD capacitors. The 964i can be modified to meet the test requirements. First, four voltage ratings can be chosen: 3 KV, 7 KV, 10 KV, and 15 KV.

Next, users can determine how many cards are required. Finally, they should select the input for each card, either + (HV bus) or – (return bus). 

High-Voltage Switching Does Not Get Any Easier

The 964i is easy to set up. Up to 60 rear panel connections connect to the test fixture or DUT, while standard front inputs connect straight to the Hipot/Continuity Tester.

A single Vitrek 95X or V7X Series Hipot Tester can manage up to four 964i’s directly or up to ten through PC via the 964i’s built-in RS232 (serial) connection or optional GPIB interface. At a glance, the 964i’s LCD indicates system condition and switch activation.

The 964i High Voltage Switching Scanner

The Vitrek 964i High Voltage Automated Test Switching System sends and receives high-voltage test signals to any required test site.

Unlike traditional cable testers, which limit users to a fixed pattern, this unique feature allows them to manage each relay.

Users can access the matrix with equipment such as an LCR meter or DMM if mux cards are available. As a result, the system is highly repeatable, with no operator interaction and automated data acquisition.

With voltage switching capabilities of up to 15,000 volts and current switching capabilities of up to 40 amps, the 964i can handle virtually every test requirement. 

The 964i rear panel accommodates up to 60 output terminals. Unit shown above with 16 + terminals (HV) and 16–terminals (return). The 964i ships with mating connectors for all +/– HV terminals 7 KV and higher. Custom length HV lead sets are optionally available. Image Credit: Vitrek, LLC
