BATTERY CHARGING AND BATTERY BACK-UP
!
WARNING ! THESE UNITS ARE POWER SUPPLIES AND
NOT BATTERY CHARGERS. DO NOT CONNECT THESE UNITS DI-
RECTLY TO A BATTERY
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 peri-
ods. This is harmful for the power supply. The charge limiting resistor will
limit the charging current, thereby, ensuring that the maximum charging cur-
rent is well below the current limit value of the power supply.
