20kW high voltage power supplies from HiTek

The system’s arc protection is so good that the output can be shorted to ground repeatedly in quick succession, with no damage to the supply. The supplies are highly stable: output voltage changes by less than 0.1 per cent for a zero to full load change in load current and the output will recover to within ±0.5 per cent of set value in less than 100ms from the removal of a short circuit. Ripple is less than 0.1 per cent peak-to-peak of rated output. The temperature coefficient is less than 200 ppm/°C and drift is less than 0.5 per cent in 8 hours after 1 hour warm-up.

A full remote interface incorporates both digital and analogue control and monitor signalling. All are optically isolated to provide an efficient and versatile power supply.
