The Rohde & Schwarz HMP4030 is a three-channel programmable DC power supply delivering 384 W total output power for laboratory, engineering, and industrial test applications. Each channel provides 0 V to 32 V at 0 A to 10 A with 1 mV voltage resolution and 0.1/0.2/1.0 mA current resolution. Linear post-regulators ensure voltage ripple and noise below 150 µVrms, with voltage stabilization to ±0.01% + 2 mV and current stabilization to ±0.01% + 250 µA.
