SHNITPWR 12V 15A 180W Power Supply Adapter 110V / 220V AC to DC Universal Regulated Switching Power Converter Transformer LED Driver for LED Light Strip 3D Printer CCTV Security System LCD Monitor

This works great. I am using it to power 12V Diesel Heater in my year round camper. There are no instructions but the AC hookup is clearly marked… on the far left side of the unit there are 3 screws. One labeled with the ground symbol (for your green wire), one labeled “N” ( for your white wire) and the last labeled screw for your black wire. The 12V adjustment screw is a plastic yellow screw just behind the AC screws. Counterclockwise to increase the voltage, clockwise to decrease the voltage. You will need a volt meter on your plus/minus DC connection to zero the voltage in

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.

I have two of these and they both are working great

PRODUCT DESCRIPTION The 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 RECEIPT The 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 PERFORMED I 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! SUMMARY I 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!

Perfect power supply for my diesel space heater, it provides enough current and voltage to run on low or high settings.

Works awesome for trains set extra power supply!

Good product works great easy to use and looks good

This is the 3rd one I have ordered in about a year. The first 2 went bad. The first one over the winter, the second was due to a lightning strike close by. If this one goes bad in a short time, I'm going to find a different product to replace it. The third one arrived with a dent, but is currently working properly. It was relatively inexpensive and very easy to install, but so far I haven't had one last a significant amount of time.

Excellent product, works great.

Wir haben dieses Netzteil in unserem Wohnwagen verbaut da dass alte zu laut war ( Gebläse ). Dieses ist absolut Geräuschlos!!! Das Gebläse springt nur unter Volllast an und das ist so gut wie nie...würden wir sofort wieder kaufen und zu 100 % weiterempfehlen. Wie lange es hält wird sich mit der Zeit zeigen.

L’alimentatore non è di fattura raffinata, arriva in una scatola senza ulteriori indicazioni tecniche o fogli allegati. Fa pensare che sia fatto all'insegna di "quel tanto che basta". Questo gli permette di avere un costo competitivo e, credo, di soddisfare la maggior parte delle necessità. Una etichetta apposta su un lato dell’alimentatore indica che si tratta di un alimentatore da 12Volt con una corrente massima di 20 Ampere. Avevo segnalato che per altri alimentatori del genere viene consigliato di non superare l'80% della potenza/corrente massima e ringrazio il venditore per avermi confermato che anche in questo caso è consigliabile stare entro l'80%, che sarebbe 196W/16A. Purtroppo questa dell'80% pare sia una pratica diffusa tra questo genere di prodotti ma in altri alimentatori a volte lo si trova indicato nella descrizione o altre volte in un foglio allegato. Voglio sperare che si siano ancora anche prodotti seri, verosimilmente più costosi, che indicano il carico che possono reggere continuativamente e magari hanno del margine. È adatto ad alimentare impianti o apparecchi che funzionino a 12V. La corrente di 20(16) Ampere è il massimo da non superare ma l’alimentatore va bene anche per apparecchi che richiedano meno corrente. Una peculiarità di questo modello è che utilizza un raffreddamento solo passivo, per cui non produrrà rumore, mentre il modello superiore, da 360W(290W?) è dotato di ventola. Un selettore accessibile dal fianco permette di scegliere tra una tensione di alimentazione di 110 o 220V. Il voltaggio d’uscita è variabile tra 10,2V e 13,8V attraverso un trimmer posto a fianco della morsettiera ma un po’ verso l’interno, che è accessibile ma non tanto. Un LED verde a lato della morsettiera indica lo stato di funzionamento. Ha delle asole e dei fori che possono servire per il montaggio su una superficie. La morsettiera prevede tre morsetti per l’alimentazione (terra e due poli) e sei morsetti d’uscita per il 12V, permettendo di connettere separatamente tre coppie separate di fili. Ora non ho un impiego gravoso dove poter testare la sua potenza, e non ho neppure esperienza circa il suo comportamento a lungo termine. Se il carico previsto dovesse essere prossimo ai 200W, magari è meglio utilizzare un alimentatore che abbia più margine.
