EHT power supply suitable for driving TELTRON tubes and electrostatic experiments. The adjustable 5kV output is fully isolated and the output is monitored by a digital display. Output current is electronically limited to 2mA and the outputs are also current limited by 100k resistors to avoid larger transient currents. In addition to the 0-5kV outputs, there are further outputs linked by 25MΩ resistors. This provides an EHT output appropriate for electrostatic experiments with a short circuit current of 60µA. The switching transformer is specially wound so the output maintains a stable voltage with time, as opposed to most other commercial brands where the voltage will drop with time. An auxiliary output is provided to drive cathode heaters etc. An Independent earth terminal is available for earthing of any one of the five output sockets.
- Continuously variable, 0-2.5kV or 0-5kV at a maximum current of 2mA
- Auxiliary output, 6.3V AC at 1A, protected by resettable fuse
- Bright 12.5mm green LED display indicating EHT output
- Shrouded sockets suitable for standard 4mm plugs or shrouded plugs
- Secondary outputs with 25MΩ safety resistors
- Independent Earth Terminal for earthing of any one of the five output sockets
- Suitable for Key Stage 3+ (age 11 and above)
