Nice and quiet, plenty of power. Been using it to power my 600 watt 11 meter amplifier and it hasn't missed a beat. I set the voltage to 14.5 volts and using a panel mounted digital volt meter to monitor output there is 0 voltage drop with amplifier wide open. Thinking about getting another one and stacking them together so I can run my bigger amplifier. Some say that it can't be done, don't believe it, I've got 2 50's stacked and it works just fine. Just set voltage separately before stacking and you'll be fine. Also make sure that all your connecting wires are equal lengths and same wire size. I've seen these power supply builders on u tube using up to 8 to 10 of these switching power supplies with no problem for those guys that run some BIG boxes that do 4000 or more watts easily.

Works as described. Only issue is a bit of confusion with the CC /CV settings.... Mine came with a CC dial and the product page never mentioned it having one. Not really a bad thing, just added information on the page would be nice.

Great item worked really well very fast shipping

Terminals not labled

I bought this to power an amp for a subwoofer I put in my gym. The output voltage is so noisy it nearly blew my sub, and constantly cycles the sub with loud line noise. Completely unusable. What a waste of my time and effort.

Perfect works beyond what you expect.

It works but I am still in process setting up my cooling unit for CPU and Refrigeration thermoelectric Generator Peltier Cooler Module Kit .I'll let you all know how well it turns out and post pics when done.

Use it to powerup my stereo equipment

無負荷であれば13V程度出ますが、負荷が掛かると10V位まで電圧が下がるので使えません。
