DC-DC VEHICLE CHARGING
Important note: PowerTop must be ON for charging (See page 5 for on/off location)
If you have an external DC-DC charger they must meet the following requirements:
•
25A
MAXIMUM
charge current
•
Boost 14.2v
•
Float 13.7v
A “smart” or electronic-alternator is wired through a DC-DC charger into the GREY Anderson socket. Vehicles made after 2011
often have smart-alternators. A suitable DC -DC charger for this hookup is the CTEK D250SA.
If you have an external DC-DC charger they must meet the following requirements:
•
20A maximum charge current
•
Bulk 14.2V
•
Float 13.7V
If the DC-DC charger meets these requirements connect the device to the
Grey
Anderson connector labelled 50A
Battery Output.
Charging Status LEDs
FLAT BATTERY LED
will switch on when battery voltage drops below 11V and will switch off when
battery voltage is greater than 11V. When the FLAT Battery LED is on an internal audible alarm will
also activate.
BOOST LED
indicates that the battery is being charged via the Solar/Ext (RED Anderson) and Vehicle
(Blue Anderson) inputs or on an AC charger. The Boost cut out voltage is 14.2V and will cut in when
the battery voltage drops below 12.7V.
FLOAT BATTERY LED
will switch on when the BOOST cut-out voltage is reached and will switch off
when the Boost cut-in voltage is reached. The Float LED indicates the battery is not being charged
via the Solar/Ext (RED Anderson) and Vehicle (Blue Anderson ) inputs.
Vehicle LED Operation
The Vehicle LED will turn on when the voltage on the B l ue Anderson input is above 13.2V and will
turn off when the voltage goes below 13.2 V.
