The units have an output voltage variable from zero to 10kV (KV10-120), 15kV (KV15-80) or 30kV (KV30-40) with accurate metering on both the output voltage and current. A zero-voltage interlock is provided, ensuring that the output may only be energised with the voltage control at zero.
The output voltage and current are metered by large, accurate true RMS digital meters. The meters are backlit and have a digit height of 19mm.
The test object and output are protected by an adjustable current trip. The trip level may be set to 10-110% of the rated output in 10% steps. Breakdown of the test object is visibly indicated. The unit must be manually reset after a trip condition before testing can be resumed.
A pre-selectable test timer is provided for timed tests of 5, 10, 15, 20, 30 seconds, 1, 2, 3 or 5 minutes. An alarm sounds when the test time has ended.
The units feature automatic mains voltage selection and an external 24Vdc interlock circuit for connection of emergency off switches aned enclosure interlocks.
The unit is supplied in a compact, portable case with a permanently connected 2 metre long HV output lead. An ES30 earthing stick is also supplied as standard.
