Microtest 7631 Hipot Tester (8-Channel)

The Microtest 7631 Hipot Tester delivers multi-channel electrical safety testing with 8 base channels expandable to 72 channels for high-mix transformer, coil, and wire harness production lines. Supporting AC withstand voltage up to 5000 V at 30 mA, DC withstand up to 6000 V at 10 mA, and insulation resistance measurement up to 12,000 MΩ, the 7631 covers the full range of dielectric strength and insulation tests required by IEC, UL, and other international safety standards.

Scalable Channel Architecture

Channel expansion from 8 to 72 makes the 7631 uniquely suited for multi-winding transformer testing where every winding combination must be tested for dielectric withstand, a 10-winding transformer requires 45 unique winding pair tests, which the 7631 executes automatically via its internal scanner matrix. The modular expansion approach allows manufacturers to start with 8 channels and add capacity as product complexity increases.

Production Integration

Programmable test sequences, pass/fail comparators, and handler interfaces support fully automated production line integration. Test results are stored and traceable for quality audit compliance. Barcode-triggered test program selection enables mixed-model production where different transformer or coil variants run on the same test station.

Applications

Transformer manufacturers, motor winding facilities, multi-tap inductor producers, and electrical safety testing laboratories all deploy the 7631 for multi-channel hipot verification. The expandable architecture makes it the preferred choice for facilities producing a wide range of wound components with varying winding counts.
