QBR101B Battery Regulator
The QBR101B Battery Regulator maintains the charging of the
integral 12 V battery. The charge/recharge control includes a
temperature compensation function as well as deep discharge
protection of the battery. QBR101B also allows simultaneous inputs
from both a solar panel and mains (AC) power.
QBR101B Battery Regulator
Also included are LED lamps for indicating Battery OK/Low and
Charge/Recharge conditions. In order to maximize autonomy time, the
lamps are activated only while pressing the ON button.
QBR101B is a rail-mountable unit allowing easy maintenance.
Transient Protection Devices
Each sensor input in the QML201 has varistor (VDR) protection
against induced transients. The maintenance terminal I/O port has
transzorb diodes in their inputs. A coaxial surge arrestor is used for
the RF signal input when radio or satellite equipment is being used.
In case of long signal cables, additional transient protectors can be
installed on the DIN-rail. These surge arrestors consist of a
combination of VDR, gas discharge, transzorb diodes and coils, thus
providing excellent protection.
These are easy to change in the field without tools. In addition, these
devices are industry standard and readily available locally, too.
