OWON SPE3102 30V 10A Programmable Lab DC Power Supply

 The Owon SPE3102 is a very compact single channel DC benchtop power supply with all the regular features such as over voltage (OVP) and over current protection (OCP). It has a high resolution at 10mV/1mA. The display is a high resolution 2.8" LCD which displays set, limit and momentary parameters. The SPE 3102allows you to monitor the voltage and current in real-time, using graphs on the display. You can store and edit up to 4 groups of output waveforms. The power supply can be hooked up to a host PC with USB and communicate via SCPI. It makes for a great, simple, slim form factor power supply with plenty of power for beginners.

The following steps check basic current functions with a short across the power supply's output: 

  1. Connect a short across (+) and (-) output terminals with an insulated test lead on this channel. Use a wire size sufficient to handle the maximum current.
  2. Set the output voltage to the maximum rating on this channel.
  3. Turn on the channel output. Ensure the channel you used is in Constant Current output mode.
  4. Set some different current values on this channel; check if the actual current value displayed is close to the set current value, and to check if the actual voltage value displayed is nearly zero.
  5. Check that if the output current can be adjusted from zero to the maximum rating, When it is set to the maximum or minimum, a beep is heard, indicating that the limit has been reached.
  6. Turn off the channel output and remove the short circuit from the output terminals.
