The Stanford Research Systems PS365 is a high-voltage DC power supply engineered for precision applications requiring stable, adjustable positive voltage output across 100 V to 10 kV. Part of the PS300 series, the PS365 delivers 10 W of clean power with output ripple below 0.01% of full scale (300 Hz to 300 kHz), making it suitable for sensitive experimental setups in physics research, materials science, and detector biasing. The unit combines rugged, compact construction with remote control capability via analog input, GPIB, and RS-232 interfaces.
