Atten APS3005S Teardown and Upgrade
« on: March 29, 2012, 01:44:30 pm »
Hey folks,

Figured I'd try my hand at doing a teardown and upgrade video.  I picked up an Atten APS3005S power supply as I needed an inexpensive 5a variable bench supply and figured for $80US it was worth a chance.  It performs well but the junky always-on fan was really annoying so I decided to swap that out as well as put in the thermal switch that was missing from my version of the supply.

Sorry to bump an old thread, but I just wanted to chime in and say that I just got one this unit works a treat. Especially important, there is no overshoot/undershoot when switching it on/off; the old GW/Instek ones I am used to are notorious for this.

Great to hear.  Did you do the test under its rated load?  That would be best.

Unfortunately I don't have anything handy to test it, but I have run each channel at 12V/3A with no problems at all.
