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

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!

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.

Easy to instal . Runs the diesel cab heater . Yes the live brown wire has been seen to and is now safe . Well spotted if you saw it .? Please have qualified supervision when dealing with mains power, 110 or 220 volts AC .

Bought this power supply to run my diesel heater, provides ample current for the glow plug on startup and a steady supply voltage.

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.

Easy to set up, easy to adjust voltage output. Using to supply a diesel heater and it's working perfectly so far.Time will tell how long it lasts....
