inShareplus 400W 12V Power Supply, IP67 Waterproof Outdoor LED Driver, AC 90-140V to DC 12 Volt 33.3A Converter, Low Voltage Transformer with 3-Prong Plug for LED Light and Other 12V DC Products

Used to replace a damaged transformer. They did the job. The old transformed became too hot and blew up. this one did the job. No heat. All perfect.

Was exactly what I was looking for!

This is easy to install in. The quality is great.

I am using this supply to power a 12vdc motor of my Riptide swimming pool vacuum that can draw up to 18 amps and has a 40 foot cable. I checked the resistance between the three sets of wires that come out of the power supply, and they all seem to be connected together (0 ohm resistance). I soldered all three sets of positive output wires together and same for the ground outputs. Measured good 12vdc at the wire connections with motor running, didn't have a way to measure the voltage drop at the motor at the end of the 42 foot length of cable (40 foot cable + 2 feet internal) nor the current drawn. However, motor runs strong with no noticeable slow down when subjected to a healthy mechanical resistance asserted by pressing forcibly on the blade hub. As others have noted, the diameter of the three wires seem small (may each be 16 or 18 AWG) for the current rating, but no recommended line length is specified so it is good for the advertised usage (e.g. LED lighting). If there is a volt drop at the motor it shouldn't be a big deal as long as it runs strong enough, which it seems to, and the wiring out of the power supply is only about a foot long so most of the voltage loss due to higher resistance would occur there and should be minimal due to the short length. No noticeable thermal warmth of the supply during operation. The wires could possibly get warm at the 25 amp max, but that shouldn't matter as long as the load has sufficient current to meet the application needs. There are other DC supplies with up to 15.5 vdc adjustable and 30 amps, but the advantage of this one is that is advertised as waterproof and the others are not. This one is good enough and meets my application needs with margin.

I am using this light driver to power two strings of 12-volt down lights that I installed under the soffit around my house. I placed it in the attic space above my garage. It runs quiet and is warm, but not hot.

This power supply arrived dead. It had zero volts DC on either output pair when tested with a volt meter. Given the zero voltage it failed to power a 3A 12V DC LED light I was using to test the supply. Tried the same outlet and LED light with my old DC supply and it worked perfectly.

This power supply plus a Pyle 200W Marine amplifier and two Pyramid 3.25" 300 Watt High Power Aluminum Bullet Horn tweeters makes an awesome electronic dog whistle, which is very useful for training barking dogs that are otherwise not in your control. You can send ultrasonic soundtracks to the setup from your phone using Bluetooth.

I had original rated this as poor but I had by mistake place my comment on the incorrect power supple oder. This worked well for my LED Christmas Display.

Connect both power wires together, both neutral wires together and use as a power source for 8kw diesel heater. Working great so far!

The power supply is a beast. Ran it in a custom Bluetooth audio project and it powered 2 120w rms 5 1/2 in drivers and tweeters like a charm. A feature of wiring here is that you could operate two channels of it for 100w x2, or link both circuits to provide 200w. Study unit too, many practical uses for this stable 110v AC to 12v DC converter.

Good quality product although when I tested the voltage coming from each of the leads it was less then 12 volts 11.9. This is not a deal breaker but I think it would have been just a bit higher then 12. For my use it will be fine as I am running 4 18 watt led lights on a single circuit times 2 to light up a small shop.

Very easy to hook up. The fact that two 75 watt string of lights can be attached is very convenient and useful.

Works great, good value. I actually wired both outputs in parallel to maximize the power output. Works great to power my diesel heater
