SHNITPWR 12V 5A Switching Power Transformer Adapter AC 110V ~ 220V to DC 12 Volt 5amp 60W 4.5A 4A 3.5A 3A Converter LED Driver for LED Light 3D Printer CCTV Camera

First:There is zero instruction on how to wire this up.L N Ground -V -V +V +V(Line/Common/Hot) (Neutral/Line [220v]) (12vdc wiring)You MUST wire the neutral wire if you are using the 110vac setting. If you are using the 220vac the N wire will obviously carry power. The REAL complicated part is the 12vdc wiring. -V IS the ground you want to use for the 12vdc side.I wired up a small 9inch electric car fan to a radiator to cool off the air going into my air compressor tank. I used a multimeter to find that the middle -V+V is a connected channel. I used them to wire up the fan and the sensor probe I wanted to use to turn it on at the right time. If you want the fan to spin the other way you will simply switch the two wires and REVERSE THE POLARITY.Once I figured out how to exactly wire this unit it works WONDERFULLY. The price/value is perfect for my use case. I cannot complain.

This is a very nice power supply inverter. I like you can adjust the DC voltage out put. Well made also.

PRODUCT DESCRIPTIONThe unit I purchased is one that is rated to provide 12 V DC with a compliance current of up to 15 A.My application requires 12 V DC at 6 A, continuous duty. I choose power supplies that are rated for continuous load currents that are at least `twice` what I expect to need. In my case that would be 12 A. So this 15 A unit was selected on that basis.The supplier was named `SNT-POWER` in my order details page. When you get close to placing an order on Amazon, you can find out who is supplying the unit. Sadly, in my opinion, that is the only place where you can actually validate the Amazon name of the supplier.(I've been flummoxed in the past, reading reviews, where it comes out in the wash that they are talking about a product that was either from a different supplier or had different nameplated capabilities, different from those on the page I had loaded. I don't understand how that happens. But it does. So I wanted to be crystal clear.)MECHANICAL OBSERVATIONS ON RECEIPTThe unit includes a switch inside the framing. (The framing must be removed to gain access to the switch.) This switch MUST be set to the mains power you expect to supply the unit, which can accept either a nameplate voltage of either 110 V AC or 220 V AC. I received the unit with the switch set to 110 V AC, so I didn't need to alter its setting. But this inspection is very important. DO NOT FAIL to make this observation and validate the setting for your application.The unit I received was in very good shape. It was clear to me that one of the mounting holes had been used (the scratches around the hole obviously were produced by the use and tightening of a screw, with some substantial force applied.) I can't explain that. And another corner was very slightly bent. That may have happened in shipping. But it was otherwise in mint condition and I was happy to find the metal fabrication details as more than sufficient.ELECTRONICS TESTING PERFORMEDI quickly powered the unit without a load and measured the output voltage using a calibrated Tektronix DMM916. It read 12.26 V DC. I then subjected the unit to a load slightly larger than I required, applying a 1.88 Ohm load and measured an output of 12.24 V DC at the terminals. For my application, this was already sufficient. So I left the available adjustment alone.Very satisfied with this result!SUMMARYI placed the unit into service and it is working just as I hoped.If I need another similar device, I will gladly order from this supplier. Good value!

The power supply seems to be a solid product and works well. It is very straight forward in its use and connection, although some basic electronics knowledge or experience is beneficial since there are no written instructions. The delivery issues I refer to are the numerous reports of damage to the unit, including the two that I ordered, while in transport. The packaging is a simple cardboard box that offers no packing or protection from bumps, drops or knocks. The first unit I received had significant bends in 3 corners of the metal housing. These dents were worrisome enough to me that I thought it possible there could be damage to the internal electronics. I opted to return this unit for a replacement. The second unit I received was also dented on two corners, but to a lesser degree. I have some electronics knowledge and decided to inspect this unit. It sustained no other damage than the external dents and worked as expected. The design seems fairly robust.

Works awesome for trains set extra power supply!

15 min install! No messy wires hanging from mirror to power my dash cam on my 2024 GMC ACADIA! You tube video available!

Im running an Icom IC220h with no issues on this power supply, doesnt seem to introduce much noise

My CR-10 mini's PS shorted when the mosfet failed, and this replacement has kept it running strong again for almost a year.
