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