1. Technical description.
1.1. General description.
The buffer power-supply module is used for uninterrupted supply of devices requiring stabilized voltage of
12V/DC (+/-15%).
The power-supply module provides voltage within the following range:
U= 11,0V÷13,8 V
DC
of total current efficiency equal to
Imax=2,5A.
In case of power voltage decay, prompt switching to battery
supply occurs. The power-supply module has the following protections: short-circuit (SCP), overload (OLP),
overheat (OHP). It is adapted for cooperation with the sealed lead-acid battery (SLA). The power supply module
controls automatically the charging and maintenance process of the battery, what is more it is equipped with the
BAT output protections: short-circuit and reverse polarity protection. The power-supply module is equipped with
excessive discharge protection. In addition, the PSU module offers the technical output (Cx, NCx, NOx) used for
controlling the AC supply status.
