The Stanford Research PS350 is a high-voltage DC power supply for laboratory and research environments requiring stable, precisely adjustable output from 0 to 30 kV DC. It delivers up to 10 mA continuous current with exceptional voltage stability—less than 0.01% drift over 8 hours and < 0.05% RMS ripple and noise. The unit features a ten-turn potentiometer for fine voltage control, dual 4.5-digit digital displays for voltage (10 V resolution) and current (0.1 mA resolution), and selectable positive or negative polarity via internal jumper. Over-current protection and remote interlock input support safe operation in demanding test applications such as detector systems, electron gun excitation, and high-voltage apparatus verification.
