DKPS Power Supply Series

The dormakaba DKPS Series is a door power supply for electrified locks and access control devices. It converts 120 to 240 VAC, 50 or 60 Hz, into a continuous 2, 4 or 6 A supply at selectable 12 or 24 VDC outputs. Each DKPS power supply has 2 supervisory outputs (AC power fail and battery fail), and the power distribution controller board adds 2 more (DC fail and status) that can be connected to remote access control units to monitor the power supply operation. Supervisory outputs use form C relays.

The power distribution controller board provides electronic over-current protection on the voltage outputs (4 on the 2 A model, 8 on the 4 A and 6 A models) for a wide array of access control and egress door applications. Application permitting, the DKPS Series offers several standby battery options for continuous power during an AC power failure for a specified period of time.

  • Three models: DKPS-2A (2 A), DKPS-4A (4 A) and DKPS-6A (6 A), with selectable 12 or 24 VDC outputs
  • Supervisory outputs for AC power fail, battery fail, DC fail and status, with form C relays
  • Electronic over-current protection on each voltage output (4 outputs on the 2 A model, 8 on the 4 A and 6 A models)
  • Built-in battery charger and standby battery options, with immediate switch-over on AC failure
  • Fire Panel Disconnect Board (FPDB) standard; optional tamper switch for installations that must meet UL 294 Edition 6 or higher
