Redrex DC 12V 20A Power Supply 240W Transformer Universal Regulated Switching Adaptor for 3D Printers LED Strip Lights CCTV Computer Project Security

I have bought a few of these and they seems to lose voltage under load. This one dropped by less than a volt at full load and was perfect for the job. It's probably twice the size of cheaper units and loooks very well made. You get what you pay for I guess.

Bought this for a diesel heater that can take up to 15a at 12v on start up and it has no problem , the resistor can adjust it no problem and I set it up to 12.8v using volt meter as the heater will cut out if it drops below 12 on start up and now at 12.8 it fires up no problem. I've had it a month now and with daily use as its getting cold here yea this thing is running the heater be it on low power after start its not failed yet , I've had other psu's from the same maker in 5v 20a versions that power my led strings and there's still going after 2 years , good product and seem to be great quality.

Works fantastic with diesel heater

I use this to heat a 3D printer bed. It works very well, is quiet and runs cool, but beware that it might be electrically noisy and have EMI.In particular it upsets my temperature sensor when delivering higher currents >10 Amps. I put some ferrites on the output leads to compensate and smoothing caps and filters, now and it seems ok. So EMC might be an issue using this.

I was struggling to get my diesel heater to work from my Jackery on 12v. Bought this unit as it was over-specced by about 50% on amperage. It holds 12v absolutely rock solid whether I’m just starting the heater or the heater is on tickover. Will definitely be buying another for my next diesel heater for the shed/workshop.

Bought this to take the place of a hot and hummy old transformer-based psu for my car-type sub bass amplifier used in the home. Great improvement: cool running, steady voltage regulation (which you can adjust a bit if you want) and no RFI issues. More current: more thump!

Amazing replacement went into my 3D printer no problem! Easy to wire up and took 15-20min to install

Great product at even better price, good, stable and noise free output, well made and no noisy fan make this power supply great addition to my led lighting system.
