12V20A 240W DC Converter

Bought this to power some led strips around the TV , quite a lot of them to be honest for a DIY ambilight setup. Has the usual voltage pot to adjust the voltage range slightly, Good overall build quality and best of all its silent. Easy set up well labeled and I've had it over a year now running the lights daily and it's never been turned off and sits idle and consumes little to no standby power when the supply is on. Great value for money and funtcional!

great item for low prize .

Easy to get up and running powering a btf lighting led 5m strip

After a poor experience with a laptop charger type of PSU from this brand I was pleasantly surprised to find this to be significantly better. I don't have a load to be able to test it up to the full 20A at the moment but a brief test at 10A and longer tests at 2-5A showed less than 10mV drop on load vs. off load. The output is also adjustable over a reasonable range, so if you want to push it a little over 5V to compensate for some wiring loss in getting to your device then you can. Just make sure your device is happy with that little extra voltage for the case when it's not pulling current (e.g. at start up). I'm using it continuously powered but not using it at anything like 20A (<9A) so it's warm but quite comfortable. You would probably need to be careful about cooling if you were going to run it flat out for an extended period. NB. There appear to be several sellers offering what looks to be the identical PSU under a variety of different brands (spec. and pictures look identical). I just went for the cheapest. Update - After 3 years of continuous use at around 5A output it has give up the ghost. No drama and output safely dropped to ~2.5V without destroying anything downstream. Knocked off a star as off-load I did see over 8V and I would have hoped it would last a bit longer supplying such a modest current.

Comes with 7 terminals NOT 9 as shown in the picture. Only has 2 terminals for the negative output and only 2 terminals for the positive output. That means 30Amps per connection, not 20Amps.

A+

The input voltage switch is inside the cover, and there is a sticker saying "Don't open the cover". Fortunately I could see the switch through the cover holes and it was set to the correct input voltage. There is a POT to adjust the output voltage. I set to 5V and then started adding load. My PLC ran OK until I connected an LED strip, then my PLC smoked. I think the voltage jumped. I would not recommend connecting directly to digital circuits. It needs a voltage regulator. The power supply is lightweight and easy to connect AC cord and DC wires. 20A can drive a lot of LEDs.

Looks good. Works for what I needed it for.

This unit worked right out of the box. I was able to adjust the voltage as specified and it pretty well held a load. I did not load it to it's 20 amp capacity but the load was still substantial.

Used this to power 5V LED strips with an SPI controller. Performs exactly as advertised. Wish it had a plug instead of a ground, neutral, and live wire terminals for AC input, but I can't complain at this price point.
