Test a wider range of transformers at higher voltages and power

No setup changes needed — works seamlessly with AT5600 and with AT3600 Transformer Tester

Safe switching for high-power applications

Fully integrated with your AT test system

Accurate current measurement from 1 mA to 10 A with plug-in CTs

✓ MAGX – Magnetizing Current

• • • • Measure primary excitation current with an external source, up to 600 V AC / 10 A RMS / 5 kHz

✓ VOCX – Open Circuit Voltage

• • • • Measure secondary voltages with the primary energized up to 600 V AC

✓ WATX – Wattage

• • • • Measure power consumption of the transformer when energized at full operating voltage

✓ STRX – Stress Wattage

• • • • • Apply high-voltage AC to check winding strength and stability under load

Direct Fit

• Fits straight into the AT fixture bay

Automatic Communication

• Syncs with the tester to run high-voltage and high-power tests

AT Editor Control

• Adds the new “X” tests directly into your existing programs

Zero Disruption

• Maintains the same accuracy, reporting, and automation as built-in AT tests

Voltech CT0.1-1 (New, Optional)

• 1:1 ratio for 1–100 mA measurements, even while energizing at up to 600 V AC. 

Voltech CT10-20 (Standard, Included)

• 1:20 ratio for 50 mA – 10 A measurements. Supplied as part of every AC Interface package.

Plug-and-Play

• CT modules connect directly to the AC Interface with keyed fittings, eliminating setup errors

Accurate Results

• Current sensing ensures accurate, noise-resistant measurements in demanding test environments
