PS-A25T, Double Relay, Safe, Power Supply Unit

The PS-x25 family of secured power supplies converts AC power to 12 VDC power limited output with an integrated battery charger, designed for use with all of Rosslare's convertible and secure access controller units (ACU).

The PS-x25 family contains two power supplies, one for the lock output and the other for the ACU.

This design isolates the lock from the ACU, securing the functionality of the lock even if the ACU is tampered with.

When a valid code is entered via the ACU, it communicates with the PS-x25 family using a Rosslare proprietary protocol sending a command to activate the lock or auxiliary relay.

Similarly, the Release-to-Exit (REX) button is attached directly to the PS- x25 unit.

If the data line between the ACU and the PS-x25 unit is cut, the system immediately detects that the data line has been tampered with and generates a one-minute siren and closes the lock output. In addition, the auxiliary relay can be activated by the ACU.

A sealed lead acid battery charger is built-in to provide backup power for the ACU and the lock. The PS-x25 can also power an external speaker to annunciate bell and siren tones.
