2. Features
Smart alternator compatibility
Vehicle manufacturers are now introducing smart ECU (Engine
Control Unit) controlled alternators to increase fuel efficiency and
reduce emissions. Smart alternators deliver a variable output
voltage and are shut down when they're not needed. The
converter has an engine running detection mechanism. This
prevents the converter from discharging the starter battery when
the alternator does not supply power. See section 5 of this
manual for more details.
Separation of the starter battery and the service battery
The Orion-Tr Smart DC-DC Charger Isolated separates the
starter battery from the service battery when the engine is not
running.
Extensive electronic protection
Over-temperature protection and power derating when
temperature is high.
Overload protected.
Short circuit protected.
Connector over-temperature protection.
Adaptive three step charging
The Orion-Tr Smart DC-DC Charger Isolated is configured for a
three-step charging process:
Bulk – Absorption – Float.
Bulk
During this stage the controller delivers as much charge current
as possible to rapidly recharge the batteries.
Absorption
When the battery voltage reaches the absorption voltage setting,
the controller switches to constant voltage mode. For lead acid
batteries it is important that during shallow discharges the
absorption time is kept short in order to prevent overcharging of
the battery. After a deep discharge the absorption time is
