1.1
Intended product use
The Omnicharge DC battery chargers are primarily intended to charge an auxiliary or service
battery from a vehicle starter battery. The input battery voltage can be above, below or
equal to the output battery voltage. An Omnicharge DC charger allows the auxiliary battery
to be perfectly charged regardless of the input voltage, while being protected against
damage due to peak voltages.
The Omnicharge DC battery chargers are compatible with vehicles that are equipped with
variable output smart alternators (EUR 6+). The Omnicharge DC can start charging based on
a programmable input voltage range only, or in combination with an engine run signal. There
is also a separate (BMS-) control input available that enables external control for charger-on
and -standby.
