Charge Controller
The Charge Controller can be set to
accommodate either Flooded Lead-Acid
(LLA) or Absorb Glass Mat (AGM) batter-
ies. The Charge Controller is located in
the large pass-through bay. The controller
is used as a heat sink for the electronics
attached to it. It is normal for the con-
troller to become warm to the touch,
especially when processing higher
amperage. The charge controller will
automatically enter Thermal Shutdown if
it gets too warm.
Status of the charge controller is
viewed through the Aladdin System elec-
trical status display.
The RV-45D Charge Controller
includes the following:
1. Dual Battery Bank Charging -
The controller automatically sends
charge to both the House and
Engine batteries at the same time.
2. Pulse Width Modulation - Delivers all the available charging amperage until the batter-
ies reach their set point voltage (Bulk) and then it begins to taper off amperage
(Absorption) until it is reduced to all that is needed to simply hold the batteries at their set
point voltage (Float).
3. Temperature Compensation - Protects the batteries from excess water loss and/or plate
sulfating by automatically compensating for temperature changes, and adjusting the charg-
ing voltage accordingly.
4. Automatic Equalization (Only when set to Liquid Lead-Acid Batteries) - Activated
once per day. Allows weaker battery cells a chance to catch up with stronger cells. To
assure all LLA battery cells are at an equal state of charge, a delay timer is activated to
allow a short duration of slightly higher voltage.
