UH-PS3 is a metal enclosure with power supply included. It can be used with some of our online controllers, keypads, remote relay units, converters and relay boards.
It is a universal enclosure, so it can be used to include more than one product inside. There is no need to obtain a different enclosure for any new product that is wanted to be installed.
The power supply allows to charge an emergency battery, to prevent possible power-outages.
