Von Duprin/Schlage PS904 Base Power Supply (4A @ 12/24 VDC- field selectable)

Von Duprin/Schlage PS904 Base Power Supply (4A @ 12/24 VDC- field selectable)

Description: PS904 is able to accept a total of two optional distribution boards, plus one battery backup board and up to two 7A/hr batteries

Applications
The PS900 Series of power supplies works with many electrified devices including Schlage electromagnetic locks, Schlage AD Series hardwired locks, Schlage electrified mechanical locks, Von Duprin electrified strikes, Von Duprin exit devices, and many other brands.

Overview
The Schlage comprehensive line of power supplies and option boards was designed to address the changing needs of the access control market. Installation is simplified by utilizing a flat mounting design and polarized locking connectors for option boards. This design eliminates the need for racks and side connectors. The flat mounting of the option boards also provides for easier access to the terminal blocks for connection of electrified devices (such as electrified strikes, electromagnetic locks, card
readers, etc.).

Common to the line of PS900 Series power supplies is a constant output rating at both 12v and 24v settings, universal 120 VAC to 240 VAC input, and polarized option board connectors. New fire alarm interface board mounting allows outputs to be configured as switched (power cut) or unswitched (power continues) when signal is provided.
