1. Technical description.
1.1. General description.
The buffer power-supply is used for uninterrupted supply of alarm systems devices requiring stabilized
voltage of
12V/DC (+/-15%).
The power-supply provides voltage within the following range:
U= 11,0V÷13,8 V DC
of
total current efficiency equal to
I=5A.
In case of power voltage decay, prompt switching to battery supply occurs.
The power-supply has got a metal casing (RAL 9003 color) with a space for 40Ah/12V (42Ah/12V) battery. The
casing features a microswitch indicating door (front) opening and disconnection with the surface.
