Figure 12 Battery Regulator QBR101B
The maximum charging current can be set by the internal jumper
settings from 0.5 to 2.5 A being applicable for battery capacity of 4 to
72 Ah. The self-consumption from the battery is very low, less than
0.2 mA.
The LED lamps are also included, they indicate the conditions. In order
to maximize autonomy time, the lamps are activated only while the ON
button is bushed.
Mains Power Supply
The AC power supply unit BWT15SXZ is a switching power supply,
which operates from the universal AC input of 85 to 264 VAC and 47
to 440 Hz. The output voltage is 15 VDC, which is used for powering
the system connected to it, and as an input to the QBR101B battery
regulator for charging the backup battery.
AC Power Cable
If AC power (230 or 115 VAC) is available on the installation site, and/
or solar power is not feasible, an AC power cable can be used to charge
the batteries instead of the solar panel, or the batteries can be charged in
advance at the base.
