EHT Power Supply Lab

The switching transformer is specially wound so that the output
maintains a stable voltage with time, as opposed to most other
commercial where the voltage will drop with time. An auxiliary output
is provided to drive cathode heaters etc.
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
25M? resistors.
power supply suitable for driving tubes and electrostatic experiments.
Continuously variable, 0-2.5KV or 0-5KV at a maximum current of 2mA.
Two secondary outputs with 25M?resistors (total 50M for 5KV range).
Auxiliary output, 6.3V a.c. at 1A, protected by resettable fuse. Bright
12.5mm green LED display indicating output.
This provides outputs appropriate for electrostatic experiments with a
short circuit current of 60µA.
An Independent earth terminal is available for earthing of any one of
the five output sockets.
Sockets suitable for standard 4mm plugs or shrouded plugs.
