Pelicase with space for Instrument
and Leads






The 200ADM-P is a current injection system with a wide range of advanced features including phase shift, data storage, and harmonic analysis.

The unit has a range of outputs allowing injection of currents between 1mA and 200A. Voltages up to 240V are available on the main outputs allowing high impedance current relays to be tested. True RMS metering with single cycle capture is provided. Four (4) current ranges allow the full scale of the meter and trip level to be set independently of the selected output. Industry standard safety connectors are used throughout for safe, reliable convenience.

The unit has comprehensive timing system linked to the outputs allowing trip times, reset times and reclose times to be quickly measured to a high degree of accuracy. The timer includes a current operated mode and can accurately test instantaneous trips.

Two USB host sockets are provided to connect a memory key, keyboard or printer. Results of every test can be stored to the memory key in spreadsheet format for later analysis. The keyboard allows entry of a comment against each result. In addition a graphics file of the waveform may be stored to the memory key. Harmonic analysis results can also be recorded




  • Zero (0) to 200 amps output current.
  • True RMS metering with one cycle capture.
  • Variable auxiliary AC voltage/current output with phase shift.
  • Auxiliary metering input: V, f, φ, Z, P, S, PF, CT ratio, harmonics.
  • Variable auxiliary output 12V to 220V DC.
  • Multi-function auto-ranging timing system.
  • Current limit mode for fine control.
  • Data storage to USB memory key including waveform and harmonics.
  • Large back-lit liquid crystal display (LCD).
  • Automatic mains voltage selection.
  • USB keyboard/printer interface.
  • Compact and portable with shoulder carry strap
  The 200ADM-P has a flexible auxiliary AC output that can be used at up to 260V for voltage relays or up to 10A for current relays. The phase and frequency of this output are fully adjustable. This combination of voltage and current allows testing of relays that require two voltages, one voltage and one current or two currents.

An auxiliary metering module is provided that meters AC and DC voltage, current and frequency from the auxiliary outputs or external signals. The module can also take measurements in conjunction with the main current output to meter phase angle, power impedance, CT ratio and harmonics.
