Eliminate slow, error-prone manual switching. The Vitrek 964i High Voltage Switching System automates complex, multi-point hipot testing — delivering faster results, greater accuracy, and improved safety. Whether you’re testing 16-conductor medical cables, 64-pin connectors, or SMD capacitor trays, the 964i handles it all with ease.
Unmatched Flexibility: Configure up to 64 test points in a single unit — or scale up by combining multiple units for increased capacity. Choose from four voltage ratings (3KV, 7KV, 10KV, 15KV) and customize input configurations (+HV bus or -return bus) to meet your exact specifications.
Seamless Integration: Standard front-panel inputs connect directly to Vitrek’s 95X or V7X Series Hipot Testers, while up to 60 rear terminals link with your DUTs. Control up to 4 units directly from your hipot tester or 10 units via PC using the built-in RS232 or optional GPIB interface.
Smarter, Safer, Faster: The 964i’s intuitive LCD display keeps you informed with live system status and switch confirmations. No more manual reconfigurations — just rapid, repeatable results without the risk of operator error or exposure to high voltage.
