The Rigol DP832 is a programmable linear DC power supply for laboratory and industrial testing applications. It delivers 195 W across three independent output channels: two 0–30 V / 0–3 A channels and one 0–5 V / 0–3 A channel. The unit features 10 mV and 10 mA minimum resolution for voltage and current programming and readback, enabling precise power delivery and measurement. A 3.5-inch TFT monochrome display provides real-time monitoring of voltage, current, and power across all channels.
