12V 300W LED Power Supply

As advertised works perfectly

The power supply arrives in a nice looking black cardboard box boasting a cool looking holographic logo with the PSU placed inside a vacuum formed plastic insert. This is definitely one of the better quality LED drivers I've had from a lesser known brand, at least based on first impressions of the packaging, weight and feel of the unit itself. The screw terminals are covered with flip up covers and everything genuinely feels solidly built. There are no rattling components or any other visible issues that concerned me right out of the box. It's hard to make a solid call on the quality of the workmanship of internal components, as the unit is filled mostly with epoxy and only the tops of the components are exposed. Though this is a feature and not a negative as the resin filling inside the PSU has much better thermal properties than air and it will keep the unit running cooler. It also has an additional benefit as a by-product, which is the lessened chance of coil whine as everything is fixed in place and will be less likely to vibrate. As usual with any of these LED drivers or power supplies, I ran a couple of tests with my multimeter to verify it was safe to use and that it was outputting the expected voltage. The first check was to probe the earth input and verify that all the exposed metal on the fasteners and case were correctly connected to the earthing. They all checked out and I even scraped some of the anodising off the case and it also buzzed correctly for earth continuity. Knowing the earthing was good, I connected it up to mains using cable terminated with ring crimps and probed the output terminals and found it outputs 23.89V without a load. So no obvious issues with the electrical safety side either. The next test was to power up a dozen or so metres of COB LED strips and it had zero issues with them and had plenty of juice to spare. I much prefer to over-spec my power supplies, and this one gives me a lot of headroom to work with for my lighting projects. My only true complaint about this is the lack of a trim pot for adjusting the output but other than that this is an excellent power supply for the price point. If you’re confident and know what you’re doing when it comes to a mains power installation for one of these LED drivers, this is a viable option and is worth considering.

This 12V 300W power supply is built to handle the amount of power as what it describes. It has power filter inductors as well as SMPS ferrite transformer. The tab are built to handle 25 amperes of current; however the entire case is made out of metal, which means it must be connect to earth wire in order to ensure the products safety.

Sleek packaging and good design. However, Voltage breaks down during operation. I had an aaplication drawing periodically around 320W and the output voltage collapsed from 24V down to 20V which made the application stop working. The power supply good hand warm so I added fans to further cool it (not exactly the idea of a fanless supply) but nothing changed. In the end it was just about room temperature and still had collapsing output voltage. Maybe the next version more powerful would work but the product was advertised with 400W and I am well below that. Would recommend to factor in big power buffer if you choose this product

Werkt perfect

funciona como predentido, nada a dizer

Produits d'excellente qualité, le branchement est simple et efficace. Des petites protections en acrylique transparent protègent la connectique et le boîtier est naturellement ventilé. La qualité de l'ensemble est comparable à son arrivée chez moi, efficace à 100% !

Pare che funzioni bene, riscaldamento un po eccessivo se usato a limite delle sue capacità

Ne fonctionne plus au bout de 11 mois d utilisation ( non permanent ) , ne supporte même plus une charge de 1 A
