Product Details

HV Diagnostics 100 ADM-MK4 Current Injector

The 100ADM mk4 provides commissioning and maintenance engineers with a flexible system for testing protective systems. An easy to use front panel layout and a simple user interface. The status of every function can be seen at a glance, and there are no complex menus to navigate.
The 100ADM mk4 keeps the familiar user interface of previous models but adds a new metering system that accurately measures the RMS of a single cycle. It also features a new current limit mode that provides precise control of low currents, even into low impedance loads. Current limit mode also assists in testing self-powered overcurrent protection schemes.

The instrument has a range of outputs allowing injection of currents as low as few mA and as high as 100A. Voltages up to 240V are available allowing high impedance current relays and voltage relays to be tested. Four true RMS metering ranges are provided, and the full scale of the meter (and trip level) can be set independently of output tap. Industry standard safety connectors are used on all inputs and outputs for convenience, reliability, and safety.

A very flexible two channel timing system is provided, allowing trip times, reset times, and reclose times to be quickly measured to a high degree of accuracy. The timer auto-ranges to measure from 1ms to 99999.9s.

The outputs of the 100ADM- mk4 are well protected. The main output is protected by overcurrent, duty-cycle and thermal trips. The auxiliary dc supply is protected by a current limit, and the auxiliary AC supply is fuse protected.
