Von Duprin PS906-4RL-BBK Base Power Supply, 6A @ 12/24 VDC Field Selectable, 4 Relay Board Integrated Logic for Controlling Security Interlocks, Battery Backup Kit, Includes Two 7A/hour Batteries
The Von Duprin PS906-4RL-BBK Power Supply delivers a reliable 6 amp regulated output with field-selectable 12/24VDC operation and includes a factory-installed 900-4RL logic relay board along with the 900-BBK battery backup kit featuring two 7Ah batteries. Designed for advanced access control systems, the integrated logic board supports time delays, security interlocks, and auto-operator coordination, making it ideal for electrified panic devices, electric strikes, magnetic locks, and electrified trim in commercial facilities. The built-in battery backup ensures continued operation during power outages, while universal 120–240VAC input, overload protection, LED status indicators, and a secure hinged enclosure provide dependable performance. UL 294 and ULC-S318 listed, the PS906-4RL-BBK is a centralized, life-safety compliant power solution for healthcare, education, government, and high-security environments.
