1. Technical description.
1.1 General description.
The buffer PSU is used for an uninterrupted supply to alarm systems devices requiring stabilized voltage of
12V/DC (+/-15%).
The PSU provides voltage of
13,8 V DC.
Current efficiency:
1.
Output current 2,0A + 0,5A battery charging
2.
Output current 2,0A + 0,2A battery charging
Total device c battery: 2,5A max.
In case of power decay, a battery back-up is activated immediately. Battery charging preset current - 0,5A.
A metal enclosure (RAL 9003 colour) accommodates a 7Ah/12V battery and a microswitch indicates door opening.
