The T&R 750ADM mk2 is a flexible current injection system capable of supplying currents of up to 750A ac into a variety of loads. The unit is designed for testing devices used for power system protection, but can be used wherever a high current AC source is required. The 750ADMH mk2 has a maximum no load output voltage of 5V. The unit is ideally suited to all low power primary injection tasks requiring up to 750A for short periods.

The unit has two outputs, allowing injection of currents as low as a few hundred milliamps and up to 750A. Voltages up to 16V are available on the 40A output, allowing higher impedance trips to be tested. Four true RMS metering ranges are provided, allowing the full scale of the meter and trip level to be set independently of the selected output.


Primary injection up to 750A.
4V output*
16V 40A output for secondary injection.
True RMS memory ammeter with singlecycle capture.
Multi-function timing system.
Large back-lit liquid crystal display.
Thermal and over-current protection.
Automatic switch-off at end of test.
Compact and portable.
Automatic mains voltage selection*.
* See specifications.
