Note! Voltage of terminal “Output 24VDC” of
ABC is
directly linked to voltage of
AB
connected to terminal "BATTERY" of ABC, i.e. when a battery of 12 V is connected to
ABC,
the
voltage at terminal “Output 24VDC” equals to 12 V and when a battery of 24 V is connected
to
ABC, the
voltage at terminal “Output 24VDC” equals to 24 V.
It is recommended not to use
ABC as
main power supply since the reserved load
connected to
AB
circuit can be de-energized by
ABC
despite of availability of power supply line
voltage (for example, in case of short-circuit in
AB
circuit or in case of strong sagging of
charging voltage when
ABC
charges deeply discharged battery). To ensure reliable supply by
reserved load, it shall be fed from separate power unit (refer to example in Figure 7).
