PSDCB 18129B13,8V/9A/18×0,5A/7Ah Buffer, switch mode power supply for CCTV

A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of 12 V DC (+/-15%). The PSU provides voltage of U=13,8 V DC. Current efficiency:
1. Output current 18×0,5A + 1A battery charge
2. Output current 18×0,38A + 4A battery charge
Total device current + battery: 11A max.
In case of power decay, a battery back-up is activated immediately. The PSU is constructed based on the switch mode PSU, with high energy efficiency. The PSU is housed in a metal enclosure (colour RAL 9003) which can accommodate a 7Ah/12V battery. A micro switch indicates door opening (front cover).
