Von Duprin PS902 Power Supply - 2A, 12/24 VDC Field Selectable

Commercial-Grade Regulated DC Power for Electrified Door Hardware & Access Control

The Von Duprin PS902 delivers 2 amps of continuous regulated DC output with field-selectable 12 VDC or 24 VDC, purpose-built for Von Duprin electrified exit devices, electric strikes, magnetic locks, and access control systems. A single unit covers both common device voltages, eliminating the need for separate supplies on mixed-voltage installations. Grade 1 commercial rating makes it appropriate for life-safety and security applications in commercial, institutional, and multi-family environments.

The PS902 is available as a base unit or configured with optional distribution boards (2-relay, 4-relay independently controlled, 4-relay with integrated logic, 8-output PTC protected), fire alarm relay (FA), battery backup kit (BBK), and key lock cover - select the combination that matches your system design.

Key Features

  • 2A Regulated DC Output: Continuous regulated output protects sensitive electronics from voltage fluctuations and ensures stable performance across all connected devices.
  • Field-Selectable 12/24 VDC: Voltage selected at the unit during installation - no separate supply needed for 12 V or 24 V devices on the same job.
  • Optional Distribution Boards: Add a 2-relay output board, 4-relay independently controlled board, 4-relay board with integrated logic, or 8-output PTC-protected board to distribute and protect downstream circuits.
  • Fire Alarm (FA) Relay Option: Integrates fire alarm input to release electrified locking devices on alarm activation, supporting life-safety code compliance.
  • Battery Backup Kit (BBK) Option: Maintains power to connected devices during AC outages, critical for continuous access control and egress compliance.
  • Key Lock Cover Option: Restricts unauthorized access to the power supply enclosure and voltage selection switch.
  • Grade 1 Commercial Rating: Rated for demanding commercial and institutional security installations.
