Gel–Lead–Acid Accumulator Charger
This function is available in the
version only, which contains an
2N SmartCOM PRO
®
intelligent charger for an external gel–lead–acid accumulator. Charging is controlled
automatically and terminated when the accumulator has been completely charged. In
the case of power failure, the system is fed continuously by the accumulator and, upon
power recovery, the accumulator is charged automatically. A 6V or 12V accumulator
can be used and charged on condition that the power voltage is 1V higher at least than
the maximum voltage of the accumulator.
