please help I am looking for 2 power units (supply's) for 2 mobile time-lapse vcr recorders (Model name mvcr960) on the back were the plug go it says 12v dc in and sticker on back says DC12V, 2A, 12W They have a sq. 4 pin connecter on vcr units which I have for both, Got them out of a broken computer power boxes. I have tried some 12V DC 1Amps ?watts power supply's that have 2 wire that I use for my cameras but they did not work tried making the 2 wires into 4 and still nothing. Don't know if maybe they needed the full 12 watt and to be wired right. Any help would be great. Thanks for any help You can give. Mike
Hi Mike. I am not sure what the wiring diagram would be for your DVR units. I know there is a standard 4 pin unit connector that comes with our 5A 4 Pin power supply. Since the 5A unit can power any amp rating UP TO 5A, it will work as far as the load in concerned for your DVR. As far as the connector, I would say it is worth a try... It will most likely be the standard 4 PIN connector, so it should work.
Hi.. I have an LED light strip I want to power. It says it is 12 Volt 50 watts. Will you Power Supply Work.
Hi Sammer. Yes, the power supplies we have are ideal for powering an LED light array. All you have to do is hook us the output of the power supply, to the input of the strip. This is usually a 5.5mm x 2.5mm barrel connector. For a 50 watt load, you would divide that number by the voltage, which is 12V, so you would get 4.16 Amps. With amperage, you will always round up to the next highest whole number, so you will use the 12 Volt 5 Amp power supply. Good luck.
I need to replace an AC Adaptor. model: MW48-1200750 Input: 120V AC 60Hz 22W Output: 12V DC 0.75A negative polarity class 2 transformer Is the plug size/configuration determined by the voltage/amperage? Do you have a recommendation? thanks
Hi Pat***. The size and type of connector for a power supply is often determined by the voltage and amperage. For most 12 Volt DC power supplies of less than 10 Amps, the standard connector is a Barrel type 5.5mm x 2.5mm connector. This covers the vast majority of power supplies. For smaller power supplies, being 1A or less, a 5.5mm x 2.1mm barrel is sometimes used. These measurements represent the size of the barrel connector. 5.5mm represents the diameter of the outside barrel, with 2.1mm or 2.5mm is the diameter of the hole inside of the barrel. It is interesting to note that for most power supplies, the 2.1mm and the 2.5mm barrels are interchangeable, meaning that they are close enough in size that either one should work... In terms of Polarity, the standard is that the inner barrel is positive, and the outside barrel negative. All of the power supplies on this site are inner barrel positive. In the rare situation were you have a device were the inner barrel is negative, you can simply cut the wire going to the barrel connector, and reconnect with electrical tape reversed. Please let us know if you have any other questions...
