The Stanford Research Systems PS310 is a microprocessor-controlled switching high-voltage DC power supply engineered for precision laboratory and test applications requiring stable, adjustable output with exceptional low-noise performance. This instrument delivers output voltage from ±12 VDC to ±1.25 kVDC at up to 20 mA with 25 W maximum power, achieving 0.001% line regulation and 0.005% load regulation across its operating range.
Technical Specifications
Output performance is characterized by output ripple below 0.0015% of full scale (typical) and voltage accuracy of 0.05% with 1 V resolution. Current measurement provides ±1 µA resolution with ±1 µA typical display accuracy. Temperature drift remains 50 ppm/°C from 10 to 40 °C. The supply operates from 100–240 VAC, 50–60 Hz input and consumes 75 W.
Protection architecture includes arc and short-circuit detection with programmable voltage, current, and current-trip limits. Trip response time is less than 10 ms (excluding stored charge), with 12 ms typical recovery for 40% load-step changes. Output discharge reaches <1% of full-scale voltage in under 6 s with no load.
