A new EHT power unit supplying up to 5kV for experiments with Teltron tubes, spark counters and other high voltage experiments such as the shuttling ball etc. The outputs are arranged as 2.5kV – 0 – 2.5kV and are safely terminated through colour coded shrouded 4mm sockets. The EHT output current is limited to 2mA for safety. A separate heater output of approx. 6.3V at 2A is also available as well as an earth terminal to allow any of the EHT outputs to be grounded for extra safety. 5 year warranty.
