T&R KV30-40D Mk3 High Voltage AC Test System

T&R have replaced the old KV30-40 MkII with the KV30-40D, as the meters used on the old unit have become obsolete. The KV30-40D also has a timer built in as standard. The output voltage is variable up to 30kV. 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 true RMS reading digital meters. The test object and output are protected by an adjustable electronic 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 and the unit must be manually reset after a trip condition before testing can be resumed. The unit features automatic mains voltage selection and an external 24VDC interlock circuit for connection of emergency-off switches and interlock switches on the test enclosure. A test timer is provided for pre-selectable test times of 5 seconds to 5 minutes. The unit is supplied in a compact, portable case with a permanently connected 2 metre long HV output lead. FEATURES 0-30kV output voltage. Automatic mains voltage selection. Key operated supply switch to prevent unauthorised operation. Dual overload protection. Variable electronic trip - 10 - 110% of rated output. Voltage and current digital metering. Zero-volt interlock. External 24VDC interlock circuit. Test timer. Emergency stop. Visual indication of test piece failure. T&R KV30-40D Mk3 Specifications Supply Requirements 115 V/230 V+10% auto-selecting 50/60 Hz 1ph 1200 VA max.
