Rigol DP813 – Power Supplies, Output 200 W Programmable DC Power Supply

The Rigol DP813 is a single-channel, 200 W programmable linear DC power supply designed for R&D, quality control, automated testing, and educational applications. It delivers dual voltage and current ranges—0–8 V / 0–20 A or 0–20 V / 0–10 A—with programmable control and built-in measurement of voltage, current, and power. The unit combines tight regulation, fast transient response, and comprehensive protection to support demanding bench and system-level testing workflows.
