12V 100A 1200W DC Switching Power supply Adapter PSU AC-DC 12Volt Industrial Transformer Converter 0-80/50amps LED drive Lamp Meter Semiconductor Motor Pump Winch Stereos Amplifier Fan SMPS 110V/220V

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.

Great item worked really well very fast shipping

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.

The only gripe I have is where they placed the thermal sensor that turns the fan on for cooling.They stuck it between 2 transistors that dont get hot enough to ever kick the fan on.I ziptied it to a transformer because it gets hot when power consumption goes up.It works great now.Sharp looking unit too,for a power supply.Also,I dont get any noise in my radio.

I have purchased 3 of these supplies. Only one of the works as advertised. The other 2 don't output 12 vdc or the fan stalls and "clicks". I have returned the 2 supplies and purchased 1 more. If the new one doesn't work - I am done. Too bad because this can be a very good supply (100 A) for the money.

Working great

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.

Definitely not for radio equipment! Far too noisy! I wrapped both power and supply cables in ferrites which helped quite a bit but still unacceptable noise levels. FYI!

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。
