The Rohde & Schwarz HMP4040 is a four-channel programmable DC power supply delivering 384 W total output power for research, development, industrial testing, and laboratory environments. Each of the four independent floating channels provides 0–32 V at 0–5 A with up to 160 W per channel, featuring 1 mV voltage and 1 mA current setting resolution. Voltage stability holds to ≤0.01% + 2 mV under both load and line variations, while current stability maintains ≤0.02% + 2 mA. Output ripple and noise measure ≤1 mVrms (voltage) and ≤5 mArms (current). Load transient response completes in 0.95.
