QBR101 Battery Regulator
The maximum charging current can be set by the internal jumper
settings between 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, which is required at installations at remote locations.
Also included are LED lamps that indicate the conditions. In order to
maximize autonomy time, the lamps are activated only while pressing
the ON button.
BWT15SX Mains Power Supply
The Mains power supply unit BWT15SX is a switching power supply,
which operates from the universal AC input of 85 to 264 VAC and
from 47 to 440 Hz. The output voltage is 15 VDC, which is used for
powering the MAWS system, and as an input to the QBR101 battery
regulator for charging the backup battery.
