Switch Mode Laboratory DC Power Supplies
Precision adjustable supply provides adjustable 1~36VDC output with adjustable current limiting from 0~3A. It is ideal for test, measurement and service applications where tight voltage and current regulation are critical. Highly efficient switch mode design delivers outstanding performance from an extremely compact footprint. Unique separate output ON/OFF control allows voltage and current setting, with the supply output turned off.

Part of a Complete Series, this slim supply occupies little bench space while providing very high precision and 90W of continuous output.

      Use it to power my desktop centrifuge for food and medicinal science.
      Cute little guy with great range of DC output.
      Easy to use and intuitive.
      We did have to customize the leads. (bear wires and plugs, then solder onto
      generic used adapter)
      Hope that leads will be included in the future.

      Great bench supply for use in our electronics test lab. It's small, easy to adjust and the built-in meters are accurate.

      Just what I needed for my bench!

      This power supply had the voltage and current requirements I was needing on my bench. The build quality is excellent and it runs reasonably cool under full load. My first test was to charge a 12 volt 17 amp hour sealed lead acid battery. Also ran some 25 volt Dynamotors. The starting current required of those was a bit of a struggle to start but they did without failing. I have used it many times on my bench to test items and have been pleased with this supply. The large LCD display makes setup and monitoring easy. I would have liked a little more current but for the price one cannot complain. Only negative point is the shape! It is pretty deep for my bench. A more square sized case would have been better.
