This is a specially designed universal floating high voltage power source useful for supplying charge for quantitative electrostatic experiments and also for gas discharge tubes needing a filament supply, or even spectrum tubes. Provides a continuously variable output up to 5kV by a transformer having specially insulated windings to withstand EHT voltages. The fully floating EHT circuit is particularly useful for discharge tube experiments so that the positive or negative terminal may be safely connected to earth and / or one side of the filament. The transformer is tapped directly to provide 6V/1A AC or 12V/0. 5A AC filament heating supply, which is also insulated for EHT voltages. A rotary control knob provided on the front panel adjusts the EHT output from 0 to 5000V DC with a non-hazardous maximum load capacity of 3mA [short circuit current) which can be read directly from an analog moving coil meter. All outputs available through 4mm shielded sockets and are clearly marked for their respective outputs. Both input and output fuse protected. The complete unit housed in a specially designed two part aluminium extrusion with insulated plastics side supports for safety. With indicator type ON/OFF switch. Supplied complete with detachable mains lead. Operates on 220-240V AC, 50Hz.
