SECTION 3
3.4 BATTERY CHARGING & BATTERY BACK-UP
WARNING!
These units are power supplies and not battery chargers. Do not connect these
units directly to a battery.
MISE EN GARDE!
Ces unités sont des unités d'alimentation et non pas les chargeurs de batterie.
Ne pas connecter ces appareils directement à une batterie.
These units should NOT BE DIRECTLY CONNECTED TO A BATTERY for charging or for
battery back-up. Battery charging and battery back-up may be undertaken only when the
battery is connected through suitable external isolating diodes and charge limiting resistor.
The isolating diode will ensure that the battery does not back power the power supply.
When a battery is deeply discharged, it will initially draw a very large charging current
and thus, will force the power supply into current limit mode for prolonged periods.
This is harmful for the power supply. The charge limiting resistor will limit the charging
current, thereby, ensuring that the maximum charging current is well below the current
limit value of the power supply.
i
INFO
It is recommended that optional battery back-up module BBM-12100 may be
used to convert SEC-1235 / SEC-1235M for battery back-up application.
