Description and Specification for Lab Tenders
EHT Power Supply.
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. This provides EHT outputs appropriate for
electrostatic experiments with a short circuit current of 60µA. In
addition to the 0-5KV outputs, there are further outputs linked by 25MΩ
resistors. The switching transformer is specially wound so that the
output maintains a stable voltage with time, as opposed to most other
commercial brands where the voltage will drop with time. Continuously
variable, 0-2.5KV or 0-5KV at a maximum current of 2mA. Two secondary
outputs with 25MΩresistors. Auxiliary output, 6.3V a.c. at 1A, protected
by resettable fuse. EHT power supply suitable for driving Teltron tubes
and electrostatic experiments. Bright 12.5mm green LED display
indicating EHT output. Shrouded sockets suitable for standard 4mm plugs
or shrouded plugs.
