WUQ

WUQ SPD3303X-E Triple Output Power Supply 220 W

SKU CH-3FY0-T51QN

Triple-output bench supply delivers two 32 V 3.2 A channels and one selectable 2.5 V 3.3 V 5 V 3.2 A channel with timing, series and parallel modes plus USB PC control

  • TypeTest & Measurement Products
  • Three isolated outputs deliver up to 220 W total power
  • Series mode combines channels for 60 V maximum output
  • Parallel mode merges current to 6.4 A for high-current loads
  • Intelligent fan control reduces acoustic noise during operation
  • USB interface enables remote programming and PC software control

Triple-output bench supply for development

The WUQ SPD3303X-E delivers three independently controlled and isolated outputs from a single tower chassis. Two channels provide up to 32 V at 3.2 A each, while a third channel selects 2.5 V, 3.3 V or 5 V at 3.2 A. Total output power is 220 W, suited for bench prototyping and automated test sequences.

Engineers who need programmable step timing

The timing function lets users define programmed output steps without an external controller. Free PC software, remote programming support and an included LabView driver simplify integration into test rigs. Builders who require more than 220 W total, higher single-channel current or additional output channels should consider a larger unit.

Series and parallel flexibility within 220 W

Series mode combines the two 32 V channels for up to 60 V, while parallel mode merges them for up to 6.4 A. Five internal parameter groups store common setups and the graphical interface shows waveform data. The temperature-controlled fan keeps acoustic noise low during extended runs.

Highlights

  • Three isolated outputs deliver up to 220 W total power
  • Series mode combines channels for 60 V maximum output
  • Parallel mode merges current to 6.4 A for high-current loads
  • Intelligent fan control reduces acoustic noise during operation
  • USB interface enables remote programming and PC software control

Questions about this item

Do I need a USB cable to connect the SPD3303X-E to a PC for remote control?

Yes, the unit uses a USB connector for PC communication and works with the included EasyPower software or the LabView driver for remote programming.

Can I run the two 32 V channels in series with my existing 60 V test gear without exceeding the supply's limit?

The series mode on this model reaches a maximum of 60 V, so it matches 60 V equipment exactly; stay at or below that level to avoid over-voltage.

How can I verify the 1 mV voltage resolution is active after I power on the SPD3303X-E?

The front-panel display shows five voltage digits and four current digits; the least-significant voltage digit will change in 1 mV steps when you adjust the output.
