Benefits of the DP900 3-Channel Power Supplies up to 210 W

  • 3 isolated independent channels up to max. 32 V/3 A; max. 210 W total.
  • Excellent values for accuracy, ripple, speed etc.
  • Touch screen and interfaces LAN, USB, digital I/O (depending on variant).

Rigol DP900 Series Programmable Linear DC Power Supplies

Rigol DP932A, DP932U, DP932E Power Supplies

The Rigol DP900 series includes three variants of a 3-channel programmable linear DC power supply. The variants differ in their technical specifications and features: The standard DP932A model and the educational/university DP9000U model (with safety sockets) offer 32 V/3 A, 32 V/3 A, and 6 V/3 A ranges. The DP932E model (e-commerce version) has 30 V/3 A, 30 V/3 A, and 6 V/3 A ranges. The total power is 210 W max. Common to all models is a touch screen, the possibility of internal serial/parallel connection of channel 1 and 2, protection functions (OVP, OCP, OTP) and excellent ripple and noise of only &let;350 µVRMS/2 mVpp.

  • Programmable linear DC power supplies.
  • 3 isolated independent channels up to 32 V/3 A, 32 V/3 A, 6 V/3 A.
  • Internal channel serial-parallel switching of channel 1 and 2.
  • Command processing time <10 ms.
  • Low ripple and noise <350 mVRMS/2 mVpp.
  • Minimum dwell time in arbitrary editor 100 ms (standard version A, option verion U). Max. 512 arbitrary points and various fixed basic waveforms.
  • Model DP900U with safety sockets on the front panel.
  • Protection against over voltage (OVP), over current (OCP), over temperature (OTP).
  • 4.3"/10.8 cm color LCD touch screen.
  • Interfaces: LAN/Ethernet, USB and digital I/O (depending on variant).
  • Available in 3 variants with different features/price.
