PS914 Power Supply

NOTE: This base unit is rarely ordered by itself.

PS914 power supply is specifically designed to be used with Von Duprin electrified (EL) exit devices.  As such, 16 amps of inrush power is required and the base unit by itself only outputs 4 amps.  The addition of module 2RS is required to boost the output to 16 amps.  Other features such as battery backup and fire alarm interface may be added with the addition of other modules. 

We stock several preconfigured models listed below, or you may select modules individually above to suit your needs.

PS914-2Q: used with Quiet Latch Retraction devices, operates up to 2 devices

PS914-2RS: used with EL devices, operates up to 2 devices

PS914-2RSFA: adds fire alarm interface to the PS914-2RS

Brochure Description:

Von Duprin’s power supply and option boards were designed to meet the specific requirements of electrified panic devices. Installation is simplified by utilizing a flat mounting design and polarized locking connectors for option boards. This new 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 panic devices, strikes, 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 provided.

* All PS900 Series of power supplies and option boards have been tested and certified to meet UL294.
