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.
