The Rigol DP712 is a programmable linear DC power supply for benchtop testing, delivering 0–50 VDC at 0–3 ADC with 150 W total output. Single-channel architecture with 10 mV and 10 mA resolution provides precise voltage and current control. The 3.5-inch TFT-LCD display presents real-time readouts of set voltage, set current, and power. Output stability is maintained through tight line and load regulation (both <0.01% + 2 mV/2 mA), with ripple and noise suppressed to <500 µVrms / 4 mVpp. Transient response completes in <50 µs, enabling rapid load-step testing.
