1.1. General description.
Buffer power supply modules is designed in accordance with the requirements of the (I&HAS) EN50131-6:2017
and (Access Control) EN60839-
11:2013 standard, grade 1÷2 and II environmental class. The power supplies
unitsare intended for for an uninterrupted supply of I&HAS and Access Control devices requiring stabilized voltage
of 12 V
DC (±15%).

Total current of the rec battery chargi
ng current mustn’t cross maximum current of power supply.
In case of power failure, a battery back-up is activated immediately
Depending on a required protection level of the alarm system in the installation place, the PSU efficiency and the
battery charging current should be set as follows:
* Grade 1, 2 - standby time 12h:
The 12h standby output current can be calculated from the formula:
I=Q
AKU
/12 - I
Z
gdzie:
Q
AKU
– minimum battery capacity [Ah]
Iz
– PSU current consumption (including optional modules) [A] (Table 4)
