INDIANAP0LIS --A new power supply from the Von Duprin Division of Ingersoll Rand Architectural Hardware is designed to operate a wide variety of electrical products, including EL (electric latch retraction) exit devices. The new Von DuprinR Series PS873 Power Supply features a regulated output that is field-selectable for either 24VDC @ 2 amperes or 12 VDC @ 4 amperes.

The PS873 can be ordered with three standard options: Key lock, to secure the cover for safety and eliminate tampering; Battery backup, which provides two hours of backup power at full load during an AC failure; and Fire Alarm, which provides input for a normally closed fire alarm contact.

To provide greater system flexibility, the Series PS873 is available with several optional plug-in circuit cards. The power supply will accept one or a combination of any two cards, including two-zone controller, alarm function, auto operator, security interlock, two-zone controller with time delay and fire alarm, and two-zone controller with time delay. Additional factory installed circuit cards are available for access control and delayed egress functions.

Overall size of the 19-gauge steel enclosure is 10" high x 12-1/2" wide x 5" deep.

Additional information on the PS873 Power Supply is available from Von Duprin Division, P.O. Box 6023, Indianapolis, IN 46206.
