Continuously variable output from 100V to 5kV DC. Output voltage is indicated on a 14mm 2 digit LED display. The EHT circuits are fully floating so that for certain applications the positive or negative terminal may be safely connected to earth. The EHT outputs are taken from 4mm shrouded sockets and provide 100V to 5kV DC at up to a maximum of 3mA or current limited to 60μA. A centre tapped socket is provided to give ±2.5kV DC output. An additional pair of 4mm shrouded sockets at 19mm spacing are provided giving 6.3V AC at 2A for filament supplies. There is also a separate earthing terminal. An illuminated on/off switch is mounted on the rear panel adjacent to a fused IEC mains inlet. Enclosed in a robust metal case with a durable powder coated finish. Supplied with instructions and detachable mains lead.
