Technical Details:

Input : 220/230 Volts Single Phase 50Hz. Ac supply.

Output : 25-70

KVKVA : 150-1500W

Cooling : Naturally Air Cooled. Output Voltage

Control : Stepless Rating : Continuous for testing duty.

HT CABLE : The equipment is supplied with five meters long cooper braided H.T. cable with HT plug and socket. The braiding remains on earth potential.

LT CABLE : For input supply ten meters long 3 core cable is provided.

ZERO START INTERLOCKING : This is to ensure that the H.T. shall not actuate if the voltage control knob is not at zero position.

EARTH INTERLOCKING : If proper earth is not connected the HT shall not actuate.

AUTO DISCHARGING ARRANGEMENT : The equipment consists of automatic cable discharging arrangement.

SOCKET : H.T. plug and socket has been especially developed by us with automatic earthing arrangement

METERS : mA meter and Volt meter are provided on H.T. side. The meters are well protected against surges and spikes.

OVER VOLTAGE PROTECTION : H.T. Automatically trips in case of output voltage exceeds the preset level.

SURGES AND SPIKES PROTECTION : During the testing surges or spikes are often generated due to short circuit. The equipment is fully protected against these.
