This is a battery back up power supply, works perfect with a 7hr battery
Good for the money, workes as well as ones double the cost, fitted a few with no issues
Nice little power supply, easy to fit , but doesn't have a flt relay onboard
I bought this couple of weeks ago. Excellent choice if you're looking for a small stable 12v power supply for your door entry systems, backed up by battery.
Small and easy to install.
