The Rigol DP811A is a single-channel programmable linear DC power supply delivering 200W across dual output ranges: 0–20V/10A or 0–40V/5A. Built for R&D, education, and benchtop testing, this instrument combines precise voltage and current control with exceptional stability. Ripple and noise measure <350 µVrms / 3 mVpp on voltage and <2 mArms on current. Transient response completes within 50 µs, while line and load regulation hold to <0.01% + 2 mV (voltage) and <0.01% + 250 µA (current). A 3.5-inch TFT LCD display (320 × 240 pixels) shows real-time voltage, current, power, and waveform data. The unit integrates overvoltage, overcurrent, and over-temperature protection as standard. Dual USB ports, optional USB-GPIB, and standard LAN/RS232/Digital I/O on "A" models enable remote operation via SCPI and LabVIEW. Programmable timing, delay, trigger output, and recorder functions support automated test sequences. Input accepts 100–250 VAC at 50–60 Hz. Benchtop form factor weighs 10.3 kg and measures 239 mm (W) × 157 mm (H) × 418 mm (D).
