Benefits of the DP2031 3-Channel Power Supplies up to 222 W

  • 3 isolated independent channels up to max. 32 V/3 A; max. 222 W total.
  • Excellent values for accuracy, ripple, speed etc.
  • Touch screen and interfaces LAN, USB, RS232, digital-I/O, optional GPIB.

Rigol DP2000 Series Programmable Linear DC Power Supplies

The Rigol DP2031 is a 3-channel programmable linear DC power supply from the DP2000 series. The device offers 32 V/3 A, 32 V/3 A and 6 V/5 A (optional 10 A) output ranges and high resolution measurements down to 1 µA current. The total power output is 222 W max. The power supply features a touch screen, internal serial/parallel switching of channel 1 and 2, protection functions (OVP, OCP, OTP), and excellent ripple and noise of only <350 µVRMS/2 mVpp.

  • Programmable linear DC power supply.
  • 3 isolated independent channels up to 32 V/3 A, 32 V/3 A, 6 V/53 A (or optional 10 A: Channel 3 has two ranges 6 V/5 A and optional 6 V/10 A. When the unit switches to 6 V/10 A, both channels 1 and 2 switch to 32 V/2 A).
  • Internal channel serial-parallel switching of channel 1 and 2.
  • High measurement resolution 1 µA (low-range current).
  • Command processing time <10 ms.
  • Low ripple and noise <350 mVRMS/2 mVpp.
  • Minimum dwell time in arbitrary editor 1 ms. Max 512 arbitrary points and various fixed base waveforms.
  • Over voltage (OVP), over current (OCP), over temperature (OTP) protection.
  • 4.3"/10.8  color LCD touch screen.
  • Interfaces: LAN/Ethernet, USB, digital-I/O, RS232, optional GPIB (GPIB and RS232 share a port, so the GPIB option can only be installed instead of RS232).
