The buffer power supply


The buffer power supply is intended for the uninterrupted supply of demanding devices stabilized voltage of 12V DC (+/- 15%). The PSU supplies voltage U = 13.8V DC with current efficiency I = 4.5A + 0.5A battery charging  for KT-1-PCB controller (1 door) and for KDH-KS2012 / 24-IP / RS controllers.  In the event of a power failure, it is instantaneous switching to battery operation. With high energy efficiency and placed in a metal casing (RAL 9003 color) with place for 7Ah / 12V battery. The housing is equipped with a microswitch signaling the opening of the door (front). During normal operation, the sum of the currents consumed by the receivers may not exceed I = 4.5A *. The maximum battery charging current is 0.5A *. Total current of receivers + battery is max. 5A
