Product overview
Supply Requirements 115V/230V±10% auto-selecting 50/60Hz 1ph 1200VA max.
Output The output of the KV30-40D Mk4 is supplied via a permanently connected partially screened high voltage cable. This stows in the lid for transit along with the ES30 earthing stick.
The output of the KV30-40D Mk4 is rated at 40mA on a duty cycle of 5 minutes on/15 minutes off or 20mA continuously. These ratings are based on an ambient temperature of 25°C.
Metering The output voltage and current are metered by large, accurate true RMS digital meters. The meters are backlit and have a digit height of 8mm and analogue simulation.
Optional Test Timer An optional pre-selectable test timer can be 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.
Overload Protection Two overload protection circuits are provided on the units. The first is user selectable, and allows trip currents between 10% and 110% of the rated output to be set. A trip condition is indicated by an illuminated push button and an audible alarm. The second trip circuit is a magnetic circuit breaker operating on the primary of the HV transformer. This operates on large overloads (such as flashovers).
Accessories supplied with unit Supply lead, spare fuse set, operating manual, 5m earth lead, ES30 earthing stick.
Protection and Safety In addition to the output protection the input and control supplies are protected by fuses. All units are designed to meet the requirements of BS EN61010. An earth terminal is provided on the transformer which must be connected to a low impedance local earth. An emergency stop will cut all power to the output, when activated.
Temperature Range Storage -20°C to 60°C Operating 0°C to 45°C
Dimensions Weight 300 x 400 x 470mm 42kg
