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: http://www.amazon.com/Tekpower-TP3005T-Variable-Linear-Supply/dp/B00ZBCLJSY/ 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. http://www.tme.eu/en/details/nsp-3630/one-channel-power-supplies/manson/ Here I've wrote more about it (the whole thread my also be useful for you): https://www.eevblog.com/forum/testgear/small-power-supplies-do-they-exist/msg807010/#msg807010 |

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! |
