DESCRIPTION
A buffer PSU is intended for an uninterrupted supply to alarm system devices requiring stabilized
voltage of 12V DC (+/-15%). A linear stabilizing system, which has been used in the unit, provides voltage with
a lower level of noise and a quicker response to interference when compared to a switched-mode regulator.
The PSU provides voltage of Uout = 12,8V ÷ 13,8V DC during buffer operation, with current capacity:
1. Output current 1A (without a battery)
2. Output current 0,9A + 0,1A battery charg
Total current of the receivers + battery: 1A max.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal
enclosure which can accommodate a 1,2Ah/12V battery. It features a micro switch (TAMPER) that indicates
door opening (front cover).
