1. Technical description.
1.1 General 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 charge
Total current of the rec battery: 1A max.
In case of power decay, a battery back-up is activated immediately.
The battery is protected against
over-discharge (UVP).
The PSU is housed in a metal enclosure which can accommodate a 7Ah/12V battery. It
features a micro switch (TAMPER) that indicates door opening (front cover).
CAUTION!
In case of using the PSU for CCTV, KD, SSWiN devices (or other, of similar application), it
is recommended to use an over voltage protection module MZN1 in the output circuit of DC power.
