4 Constant current testing with greater than 2A drive
The simplest way of testing with an apparent drive of
greater than 2 amps is simply to use more than one turn of the drive
signal through the core or transformer under test.
For transformers or cores that require greater drive, or
when the resulting drive voltage is too small for the AT to stabilize
properly, then the AC Interface accessory may be used to provide up to 10A
of constant current AC drive.
4.1 Equipment Required
- AC Interface.
- VOCX test. (MAGX is useful during program development.)
- A current-sensing resistor.
- A step-down power transformer.
