RCI DKPS-4A Power Supply 4A Charger for Access Control and Egress Doors

Optimize uptime and simplify installation for access control and egress doors with the RCI by dormakaba DKPS-4A power supply. This purpose-built power supply delivers a continuous 4A output with switchable 12V or 24V DC, converting 120–240VAC input power to reliable, hardened DC for locks, strikes, and related hardware. The DKPS-4A includes eight electronically protected outputs and built-in overcurrent isolation so a single device fault won’t take down your entire door cluster — critical for security and surveillance installations.

For system monitoring and compliance, form C supervisory relays provide AC fail, battery fail and DC status signaling to access control panels and fire systems, while front-door LEDs and optional tamper switches speed troubleshooting. The enclosure supports up to two 12AH batteries for extended standby power and automatic unlocking during fire events. Ideal for commercial buildings, schools, healthcare and multi-tenant sites, the DKPS-4A power supply streamlines battery backup, monitoring and distribution in one robust unit. Add the DKPS-4A to your next security or access control project to ensure continuous, monitored power — contact us to specify this unit for your installation.
