OPERATIONAL FEATURES
AUTO DETECT
This product includes the exclusive “Auto-detect” feature for the charging of batteries. With this
new technology, the power converter will evaluate the charging cycle of a battery, determine
the type of battery being used, and then choose the appropriate charging program(profile) to
provide for the best performance and maintenance of that battery.
Because of the differences of Lead Acid, AGM and Lithium type batteries, a system that provides
a charge to the battery or batteries must be able to accommodate the different charging
requirements. With the use of the “Auto-detect” product, the charging requirement is able to be
“detected” and is then automatically set for the type of battery being used. For standard Lead
Acid and AGM batteries, WFCO power converters still use the Three-Stage Smart Charging to
effectively maximize battery life by monitoring through the different phases of the charge cycle.
On the other hand, Lithium batteries will prefer the use of only two stages when charging, and
therefore the power converter will charge using the WFCO Two-Stage Smart Charging system.
THREE-STAGE SMART CHARGING
In order to maximize battery life, it is best to charge batteries slowly, keep them topped off
with a trickle-charge when the RV is not being used. The 3-Stage “smart” charger continuously
measures the battery voltage output and regulates the amount of charge using three modes of
operation; Absorption, Bulk and Float modes.
All WFCO power converters are automatic three-stage switching power supplies. The converter
senses which mode it needs to be in by checking the RV system voltage.
