Flexible and easy to use, the T & R 100ADM is a must-have for any maintenance/commissioning professional testing protective systems.

The 100ADM’s main output is equipped with four taps and allows the user to select output voltages of up to 240V and output currents of up to 100A.  The system is designed to give users full control while remaining simple to use and includes a metering system which accurately measures the RMS of a single cycle and a current limiting mode which allows the user to take control over low currents (even when fed into low impedance loads).

T and R’s 100ADM uses a two channel timing system. This function gives the ability to easily measure trip times, reset times and reclose times, all with an extremely high degree of accuracy. This timing function is autoranging from 1ms to 99999.9s.

This secondary current injector is suitable for use in a wide variety of applications including under/over voltage, undercurrent, instantaneous overcurrent and ground fault relays, IDMT overcurrent relays, neutral voltage displacements, directional overcurrent (basic tests), auto reclosers, lockout relays, tripping relays, voltage regulating relays, miniature circuit breakers and thermal relays.

Worried about safety? The 100ADM’s output is protected by overcurrent, duty cycle and thermal trips while the auxiliary DC power supply is protected by a current limit. The auxiliary AC supply is protected by a fuse.
