1.1 General description
A buffer PSU module is intended for an uninterrupted supply to devices requiring stabilised voltage of
12V/DC (+/-15%) . The PSU module provides voltage of 13,8 V DC with current capacity:
1. Output current 3,0A + 0,5A battery charge
2. Output current 2,5A + 1,0A battery charge
Total device c battery: 3,5A max.
In case of power failure, a battery back-up is activated immediately. Battery charging current is preset to 0,5A.
