Rohde & Schwarz HMP4040 DC Power Supply, Quad Output, 4x 32 V / 10 A, 384 W The R&S HMP4040 is a four-channel DC power supply offering a maximum output power of 384 W. The total load can be distributed as desired over the separate channels. 160 W of channel power is available – in any voltage/current distribution. Four galvanically isolated, floating output channels with overload and short-circuit protection are available. The channels can be connected in series or parallel to obtain higher voltages or currents up to a maximum voltage of 128 V or a maximum current of 40 A. All basic functions of the R&S HMP power supplies are directly accessible on the front panel. The rotary knob plays a key role. It is used to set the voltage, current, and limit values for the various protection functions. Features: Number of output channels: 4 Output voltage per channel: 0 V to 32 Vdc Maximum output current per channel: 10 A Maximum output power per channel: 160 W Total output power max.: 384 W Three-year warranty All channels galvanically isolated and floating All channels have the same voltage range All channels have overload and short-circuit protection Parallel and serial operation Voltage ripple (20 Hz to 20 MHz): < 1.5 mV (RMS) (meas.); Current ripple < 1 mA (RMS) (meas.) Load regulation (load change from 10 % to 90 %): Voltage ±(% of output + offset) < 0.01 % + 2 mV; Current ±(% of output + offset) < 0.01 % + 250 μA Programming accuracy: Voltage ±(% of output + offset) < 0.05 % + 5 mV; Current ±(% of output + offset) < 0.1 % + 5 mA LAN / USB interface Optional 115 Vac / 230 Vac ±10%; 50-60 Hz operation Weight: 12.8 kg (28.2 lb); Size: 136 mm (5.35 in)H x 285 mm (11.22 in)W x 405 mm (15.94 in)D Compare at $3,165 New!
