Functions, inputs & outputs
3 - SMART KEY (ON/OFF):
This button turns the power supply on and off.With the power supply
turned off, a quick press (1 second) turns the power supply on.
Note. If the power supply is disconnected from the outlet while being turned on, when reconnecting
it to the outlet, the power supply will be turned on.· Through this key it is possible to set the operation
mode with fixed voltage of the power supply.
Note. If the power supply is turned off (but kept connected to the outlet) and its temperature is high,
the SMART COOLER can be activated at low speed for up to 20 minutes.
1 - OUT BATTERY:
To connect the positive (+) and negative (-) cables to the battery or 12V devices.
(See recommended gauges on page 10).
IMPORTANT:
Never reverse polarity. Connect the battery(ies) and audio system with the power
supply off.
2 - SMART COOLER:
An intelligent system that controls the operation of coolers and ventilation,
varying their speed according to temperature and output current. This system ensures a useful life
for the coolers and provides a quieter ambient as the coolers only come into operation only if
necessary.
With the power supply on, a long press (2 seconds) turns the power supply off. A quick press change
the output voltage: 12.6 13.8 14.4 12.6V....(Without batteries).
4 - POWER INPUT:
The PRO CHARGER 90A is automatic bivolt (127V / 220V).
See operating mode on page 13.
Check the recommended power input specifications on page 10.
6 - SMART LED:
Power supply functions indicator LEDs.
5 - VOLTMETER/AMMETER:
Display the output voltage and current, alternating between them. In
the event of a sudden change in the voltage, the display blink. With the power supply OFF, this
display can be ON during 5 seconds. There may be up 5% error on voltage reads and 20% on current
reads.
CAUTION
Before making any connections to the battery(ies), make sure you have the
correct polarities.
