1. Technical description
1.1 General description
A buffer PSU module is intended for an uninterrupted supply to alarm systems devices requiring stabilised
voltage of 24V/DC (+/-15%). The PSU module provides voltage of 27,6 V DC with current capacity:
1. Output current 1A (without a battery)
2. Output current 0,8A + 0,2A battery charge
3. Output current 0,5A + 0,5A battery charge
Total current of the rec battery: 1A max.
In case of power failure, a battery back-up is activated immediately. The battery charging current is preset to 0,2A.
