Low stress HV power supplies

Paul Boughton

The units provide power outputs of up to 1 Watt, and are intended for mass spectrometers and similar applications, where an extremely low ripple and highly stable power supply is essential for achieving high resolution outputs.

The LS family extends from <1kV to 50kV, and builds on the expertise created through the development of Applied Kilovolts’ innovative HP range. Throughout the family, ripple is <2 parts per million (ppm), temperature coefficient is <10 ppm/¢ªC, while drift is as low as 25 ppm (0.0025per cent). Until now these levels of ripple and stability have been unobtainable with commercial high voltage power supplies.
