Seeking Bench Power Supply Recommendations
(1/5) > >>
benpharr:
I had a HY1803D variable bench power supply and it finally died on me. It would never properly regulate voltage anyway. I'm looking to take a small step up in quality and possibly features. My requirements are simple (at least 13.8V max and current limiting) and my budget is $150, though less is better. I am a simple hobbyist working with microcontrollers and low power ham radio transceivers.

One model that has caught my eye is the Tekpower TP3005T:

Does anyone have any other recommendations? Are there any features I "need" but simply don't know about?

Thanks in advance,
Ben

Look out for the power supply made for the cellphone repairmen.  They come with a 3 to 4A adustable output, an analog current meter that allows you to capture surge and know (guess) the state that the DUT is, a volt meter input, a USB socket for charging need, a RF signal strength detector.   I do not have an ebay link for you.   Aliexpress is selling.  Something like this    http://m.aliexpress.com/item/32437425333.html

I have this one and I'm happy with it.

Here I've wrote more about it (the whole thread my also be useful for you):

HP power supplies are built like a brick shit house and you can get them reasonable priced on ebay. I just got a HP 6286A 0-20V 0-10A PSU recently and really like it. Biggest filter capacitor I've ever seen too!
