PS-x25x Intelligent Power Supplies

The PS-25 family of secured power supplies converts AC power to 12 V DC power limited output with an integrated battery charger, designed for use with all of Rosslare’s convertible & secure controller units (ACU).

The PS-25 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.
