• power supply function if battery is not present.
• Emergency switch reverts to original charging system in
case of failure
.
•
quiet, compact and easy to install.
The innovative circuitry in the power service unit guarantees
greater efficiency by reducing energy expenditure. output
current is regulated both according to the needs of service
batteries and to the quantity of input energy. while travelling
the device gradually reduces the output current in the event
that the alternator is in overload conditions (eg: at night with
lights on, air conditioner on, engine idling and engine fan on, etc
…). The cooling fan is activated only if necessary and the
rotation speed is electronically controlled according to the
temperature inside the device keeping fan noise to minimum.
3. 1 protections
power service units are equipped with several protection
systems to ensure a high level of safety and security:
7
Protection type reaction type
Battery overvoltage charge is interrupted
alternator overload
Power Service automatically shuts off if the
input voltage from the alternator and / or the
engine battery falls below 12.8V
over-temperature
reduces the output current and turns off.
automatic reactivation when the device
temperature returns to an acceptable
working level
output short-circuit protection by fuses
solar panel overvoltage charge is interrupted
temperature too low
if the lithium curve is selected, then charge is
interrupted
