The Rigol DP831A is a programmable linear DC power supply delivering three independent isolated output channels rated at 160 W total power. It combines high-precision regulation with flexible channel configuration: dual ±30 V / 2 A outputs with tracking capability, plus one 8 V / 5 A channel. Resolution of 1 mV / 1 mA supports precision bench testing, system integration, and R&D validation across voltage and current domains.
