18 Channel 18 Way 12V 10Amp DC Metal Boxed Cabinet Regulated Power Supply Unit with Backup Battery Link for Burglar Alarms CCTV Cameras PTZ Access Control

Bought as Amazon Warehouse Deal. Box okay, panel had been dropped causing slightly deformed corner on door, high voltage guard broken at 1 mount. Neither problem was a show-stopper, just minor annoyance and easily repaired (5 minutes). 120vac power connector *IS NOT GROUNDED*. Ground pin on connector is not connected.5 x Smonet wireless HD cameras, up to 1Amp each. So far, so good. Set voltage output for 13 so cameras are powered and battery to be charged. Might add a schottky diode later to isolate battery charge line to allow use/charge of lithium phosphate battery pack.Power switch turns off 120v converter, but does not disconnect battery from cameras. Was surprised when arc'd a camera lead during install after unplugging power cord and turning off panel. Perhaps a security feature, but was unexpected.Should have realized prior that this panel only has knockout blanks. Used 1/2" Rolex clamps to secure camera leads ran through a short piece of rubber hose. Should keep dirt daubers out. Might need to glue in a piece of window screen over vent holes to keep insects out. This is not an outdoor enclosure, but installed in protected outdoor location and grounded panel door & box.

This is the second one of these I have purchased and used to provide battery backup to alarm systems. I'll be ordering my third very soon.

Just keep in mind to adjust voltage so you don't fry your battery.

The cabinet construction is very good and comes complete with a lock and keys. It also comes with an installation template. Works great with my CCTV set up.

I used this power supply to replace several power strips and over a dozen plug in power supplies that powered some of the security cameras at the hospital I work for. This power supply looks great and has been working great for a year now. A big perk is with the battery backup the cameras continue to work while we transfer to generator power during our monthly generator test.

These units arrived well packed, so there was no damage to the device - which is a plus since they are being installed in public areas. They are easy to install, the mounting hardware is included along with a stick-on mounting template. The power cord is included, just plug it into any outlet, as well as the battery connector (you have to supply your own 12 VDC battery). The unit functioned as expected and is compact so it's easier to install in tight areas.

I thought this was going to be a great supply for my camera system. Unfortunately I sat it aside while I had an existing supply that worked. Well now I want to change to the new power supply but it causes rolling lines going mostly horizontally. I will add pictures once back to location. I'd put 5 stars if the lines weren't there. Other installers tell me it's the supply since it doesn't do it on other supplies.

Seems like a great price for what it is. I plan on ganging or changing one of the ptcs to a glass style fuse for my dvr which draws more current than a single ptc can supply. Bought to replace the mess of adapters and cords that came with my camera system. Make sure to adjust the voltage trim!

The back up battery is a good idea.
