Von Duprin Electrical Accessories

The Von Duprin PS873 series Power Supply is designed to operate a wide variety of electrical products. EL panics require 871-2 PCB minimum. The regulated output power is field selectable for either 24VDC @ 2 ampere or 12VDC @ 4 ampere. Standard input 120VAC @ 1.0 ampere or 240VAC @ 0.5 ampere available. The PS873 can be ordered with three standard options: Key lock secures the cover to eliminate tampering and provides safety; Battery backup provides two hours backup power at full load during a A.C. power failure; Fire Alarm provides input for a normally closed fire alarm contact. When the fire alarm contact is “open”, power to locks or other component is removed. Restoring power is field selectable for automatic or manual.
The Von Duprin EPT series Electric Power Transfer provides a means of transferring electrical power from a door frame to the edge of a swinging door. The units are completely concealed when the door is in the closed position, and are ideally suited for installations involving abuse or heavy traffic.
