Locknetics PS904 Amp Power Supply

Deliver reliable, code-compliant power to your access control and security installations with the Locknetics PS904 power supply board. Engineered for integrators and security managers, the PS904 provides a constant, regulated 4A output with field-selectable 12V or 24V to support electrified strikes, electromagnetic locks and card readers without swapping hardware. Universal 120–240VAC input and battery-backup support minimize site-specific parts and keep monitoring systems energized during outages. Installation is faster and cleaner thanks to the flat mounting and polarized option-board connectors that remove the need for racks or side connectors and give clear access to terminal blocks. On-board supervision includes AC and DC monitoring LEDs plus isolated SPDT contacts for remote alarm integration, helping you meet security and surveillance monitoring requirements. Optional plug-in fire-alarm interface and rugged high-voltage protection add flexibility and safety for commercial deployments. Certified to UL 294 and ULC-S318 and compliant with RoHS, the PS904 is built for dependable, long-term operation in professional access control systems. Add the Locknetics PS904 to your next access control or security monitoring project for straightforward installation and reliable power delivery.
