Automatic Microcontroller Operation
The WFCO series of 3-stage switch mode power converter are fully automatic.
The converter senses which mode it needs to be in by checking the condition
of the battery. The three modes include:
Absorption Mode: During this mode the converter output is at 13.6 VDC range.
This is the mode that the converter will function at normally. This mode provides
the 12 VDC and the current required by the trailer.
Bulk Mode: When the converter senses that the battery voltage is less than
13.2 VDC the converter will automatically go into the Bulk Mode.
Float Mode: If the RV is not being used for a period of time and the shore power
has been left plugged in, the converter will automatically go into float mode.
The converter senses if there has been any demand. If there is no activity for a
period the converter will automatically go into float mode. When the converter
senses a demand by turning on lights, the converter automatically goes into
bulk mode and returns to absorption mode.
