Backup sources for ESS / FPS

108 items

  Back-up sources for the intrusion and fire alarm systems serve to supply electronic security systems and their components. The metal box contains the mains transformer, the power supply module itself and the battery compartment of different capacity (Ah). At the output of the backup power supply the DC voltage is mostly 13.8 V or 27.6 V with a current load of 1 to 10 A, depending on the type of the power supply.

  In the event of a power failure, the backup power supply switches smoothly to the ESS / EPS power supply mode from the battery. When the mains voltage is restored, the battery is recharged to its full capacity with a defined current, and is then maintained until the next 230 V mains failure.
