220/230 Volts Single Phase 50Hz. Ac supply.
Output:
15-220 kV
Capacity:
150-2200W
Cooling:
Naturally Air Cooled.
Control:

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.
