  • 1.5A, 3A and 5A versions with 2 x steel housing options
  • Intelligent On Demand Battery Charging
  • 2 Steel Housings Housing up to 17.0Ah Batteries
  • On Board and Optional Remote Battery Temperature Sensor
  • Supplies a nominal 27V with 2 x 12V lead acid batteries providing full standby operation
  • 2 Independently controlled outputs as standard to comply with EN 54-4 & BS 5839-1:2013 requirements
  • Battery Free Operation Option (Non EN 54-4 Compliant)

K25000 Series - EN 54-4 Approved PSU and Chargers

K25000 Series EN 54-4 Approved PSU and Chargers Fully certified to EN 54-4 power supplies provide a stable and fully regulated, true 24 Vdc output for fire alarm system applications under all power conditions. The unique regulation techniques ensure that even when running on standby batteries, a stable 24 Vdc supply is available to all parts of the system ensuring that all 24 Vdc powered devices connected are supplied with optimum power.

The powerful onboard micro controller ensures that all battery types are conditioned with optimum, temperature compensated charging algorithms to maximise battery life and maintain batteries in top condition.

Optional dual output path (KD) variant available, to provide two independent supply paths between the power supply unit and the control panel in accordance with EN 54-4 clause 6.4 and BS 5839 pt1, clause 12.2.2.m requirements.

Vimpex EN 54-4 compliant power supplies can be fitted with an optional dual fused output monitoring module to ensure compliance with European standards when supplying fire control panels with an external power supply.
