ALITOVE DC 12V 20A 240W Power Supply Transformer Switch AC 110V / 220V to DC 12V 20amp Switching Adapter Converter LED Driver for LED Strip Light CCTV Camera Security System

Good price, working great so far.

Most powerful dc power supply with no fan- This is the most powerful AC to DC power supply I can find with out a cooling fan. Convection Cooling only. 20A to 12vdc with a screw POT to adjust the DC out from a high around 14vdc so if you want to charge a 12 Battery you can do this. This is a good stiff DC power supply. Have not scoped it to see if there is any ripple or if there is how much ripple there is. I have not had the need to test this as it is powering my 12V DC motors well with no issues. My DC motors have a running current of around 5 amps. No caps for starting and it does well.

This has been 100% reliable. Been using it to power a Kenwood car stereo for the past 6 months in a custom garage radio build box. It is also running an 80mm 12v computer fan for enclosure cooling, but that pull is minimal. I've had no strange power noise coming through the speakers. The voltage was accurately tuned from the factory and with the stereo on, it remains well within an acceptable power range. The stereo is using RCA outs to a separate amp, so the draw on the power supply isn't too large.

Works very well

I've been using this to power my Vevor diesel heater. It's been great. I adjusted it to 15v and run it through a small solar charger for charging the back up batteries. I ran the power for heater directly off the junction along with the solar charging . I then used a 50A diode from the battery to back feed to the junction rail. The solar charger will not allow power from batteries to back feed. This diode will allow power to be drawn from batteries if the power supply fails or power is lost. This eliminated a need for an automatic switch which is more likely to fail.

Seems to work fine. The only thing that I do not like about it is that it has limited mounting options. A set of simple screw down brackets would have been nice.

Goes well with my vevorheater

Works better than expected to power my 100 watt output HF ham radio. It worked well all summer. Made may contacts using this as the primary power supply to a Kenwood 570-D.

En el modelo 12v 20A, nada mas se regula de 10.3v a 13v. Viendolo por detro, se ve que si viene bien armado, no se ve de mala calidad, no es nada mas un transforamdor y 2 capacitores. Trae varios filtros y capacitores de buena calidad. Lo que si me da algo de temor es que este abierta, se te cae algun liquido dentro y adios, no me ha pasado pero es una posibilidad, pero es cuestion de hacer una caja y queda. Recomiendo ponerle un interruptor, ya que saca sus chispazos a la hora de conectarlo (en la clavija).

fonctionne bien

I used this to Convert Camper Shore AC to DC to run a Vevor Diesel Heater. Works great. Some wire fabricating on the users part, but it is quite simple. Works Great so Far.

Worked great for my diesel heater

Works like a charm. Does receive feedback from my LED Controller producing coil whine, which is quite annoying. Tested without and no noise. Ensure you have a good quality LED Controller.
