Works well and great price.

Works great

I was a little concerned whether this unit was the right size for my 8kw diesel heater ; as rating is in watts & heater requires minimum 15 amps. Couldn't find info on part description . It would be nice to have bigger mounting tabs for screws , as I mounted it on a wall . Have run it for a couple of days now & it seems to work fine .

Works as described. The adjustment dial goes down to 11v and will not go lower. I'm not sure what the upper end is. I bought a c13 power cord and wire stripped it to tie it in. Would recommend watching a video on wiring it up if you are unsure, very straight forward. Using this to easier test 12v items on my vehicle.

I bought this to power two diesel heaters.Easy to hook upWorks well to power both heaters. I haven't tried starting them at the same time. But why would I?I'm shocked it even works at that price5 stars

Product seems to be good quality. Used to power a diesel heater.

Worked just fine but the housing was dented when I received it, currently used to power a diesel heater in my garage, seemingly silent operation, easy voltage adjustment,

Works great for testing car stereos.

Wired everything up on a bench first and tested, good 12V output. Plugged in my NAS which it was going to be powering (should max out at around 8A load during boot, 4A idle - well below the rated 12.5A for this supply) - got a few minutes through the boot, then I heard some weird buzzing/sparking noise from the supply, and as I moved closer to investigate, loud noise and flames shot out from the back. Unplugged it as soon as I could - fortunately the NAS was not damaged. Looks like R11 resistor is fried inside, maybe one of the components on the back, not totally clear (I am not going to open it up)Wondering if this could have started a fire in my data cabinet where the NAS normally lives, had it happened later... scary. Back it goes to Amazon, but I don't think I will chance it with another one of these cheap no-name Chinese supplies...

I’m using this for a Chinese diesel heater in my shed, I have volt meter installed and it runs the glow plug with ease, the only down side is the fan it’s very loud, it says that the fan is automatic but mine just runs full time even without a load

I purchased 4 of the 240 watt version 12-Volt DC power supplies for my LEGO room lighting project. Each of these $23 units will take the place to two (allegedly) 120 watt (10 Amp) 12-Volt DC power supplies that cost $20 each. Although the $20 power supplies are admittedly much easier to setup/install they turned out to be totally worthless as they cannot maintain 72 watt (6 Amp) output without blinking due to thermal overload protection. (Returned the junk units and left appropriately detailed 1-star review.)As for these wonders of modern production I am most impressed. Although they are somewhat more difficult to install. First you have to provide your own power cable to connect to your 120 (or 240) volt AC line. I used an old PC power cable that I cut to length, stripped the wires and soldered on ring terminal connectors. If you are using solid wires you could just as easily insert the wire into the terminal and tighten the screw.Among the nice features of these power supplies:- Between each terminal screw is a divider wall to prevent shorts.- There is a clear plastic flip-up protective cover over the whole row of terminal screws to prevent accidental contact/shorts across the terminals.- 3 separate positive and 3 separate negative terminals.- easily accessible voltage adjustment screw to fine tune the output.- Strong durable metal chassis.- Well vented chassis design with closely spaced hole pattern on top and side.- High grade components inside.This size power supply does not come with its own cooling fan. My application required me ti install it upside-down on the ceiling between the joists. Therefore the vent holes were mostly underneath the unit. As heat tends to rise normal air convection could not take place. Therefore it started to get quite warm (understatement) with just a partial load. Therefore I purchased (through Amazon) a "Noctua NF-A8 FLX, Premium Quiet Fan (3-Pin, 80mm)" for cooling. The fan itself is nearly silent. However, when I placed it against the PS chassis it was definitely audible. Although there are plenty of holes in the chassis for air flow, there was still a lot of metal (between the holes) to block air flow from a fan in direct contact with the chassis. Therefore I decided to cut an approximately 3" hole in the chassis top right over the main heat-sink. I knew this would void my warranty but figured that would be preferable to burning the house down when the PS was under the full intended load. (Burning the house down would no doubt displease my wife...)Knowing it is unwise to operate anything at or near 100% for extended periods I will keep the max load under 200 watts (of 240 watts available).When I removed the chassis cover to drill the hole I had a clear view of the internal parts. What I saw impressed me as much as anything else about the design. I am not an electrical engineer but I know some basics about electronics and circuitry. At this point I would have to look up the color codes for the values of the resistors but I immediately recognized the *gold* colored "tolerance" ring on all of the resistors, as apposed to silver or none.After I cut out the hole for the fan I attached it with 2 of the included rubber connectors and use single wires pulled out of Cat5 to hold down the other 2 corners. (I could only get 2 holes in the chassis to line up with the fan's holes.) I connected the (included with the fan) 3-pin to 4-pin adapter, then found an old PC internal drive Y-splitter power cable and cut it to use as the connector between the PS and the fan. (See picture.) Since my lighting project has the power supply driving 2 branches of lights that left the 3rd set of terminals open to run this 12-volt fan. Quite convenient.Now, with the fan running the power supply barely feels a little warm to the touch while running it at about 110 watts - so far. I do expect it to get warmer when I eventually drive it at 195 watts but I think the fan should be able to keep up. If not I'll just upgrade the fan.(Electronics 100 review: Gold tolerance equals +/- 5% of the marked value for transistors. Silver equals =/- 10% and none equals +/- 20 percent.) Yes, you can get resistors with even closer than 5% tolerance but I think that would be overkill for a basic power supply. That said, the designers and production managers clearly did not go with the cheapest parts available but hold to higher than normal standards.There is a fuse soldered onto the circuit board with clearly printed warning to only use the same type of replacement fuse. Having to unsolder/resolder a fuse would be inconvenient, as opposed to have a snap-in fuse holder. However, the soldered connection is better than a mechanical snap-in connection. Perhaps this was a deliberate choice of the designing engineer(s)? The only problem is the fuse type is not indicated... Hopefully I'll never have to replace it.Yes, I am quite pleased with this product. I highly recommend this company's power supplies for any project where you need a reliable low voltage power source.The LEGO Roboticist

The "labels" for the wire connections are embossed into the metal above the screw terminals. They are very difficult to see, and they are offset slightly from the terminals themselves. Be VERY careful to connect the wires correctly. I accidentally connected neutral to the ground terminal, and line to the neutral terminal, and burnt up something. I ordered a new one and it worked great.Also, the dimmer adjustment does not dim very much...

Purchased this product as a replacement power supply for under cabinet LED tape lights. Received it promptly but item showed slight damage and only worked for 24 hours before failing. Contacted manufacturer who quickly shipped a replacement which arrived within a few days. Very impressed with their responsive customer service!
