USING AC INTERFACE WITH STEP-UP TRANSFORMER
THE AC INTERFACE SUPPORTS TWO MODES OF OPERATION WITH STEP-UP TRANSFORMER
SINGLE STEP-UP TRANSFORMER
A single step-up transformer boosts the AT Series’ internal 270 V, 2 A, 40 W source up to 600 V. While it does not increase the available 40 W power, it enables flexible voltage and current scaling.
Recommended Type: 1:3 step-up transformer for maximum flexibility.
MULTIPLE STEP-UP TRANSFORMERS
Use this method when a single transformer cannot provide the required voltage. By combining smaller transformers, you can reach up to 600 V while still staying within the AT Tester’s 40 W internal power limit.
Primaries in Series, Secondaries in Series
3× 24–230 V transformers = 690 V output
Primaries in Parallel, Secondaries in Series
3× 110–230 V transformers = 690 V output
