Advanced, 3-Stage
Battery Charger
Your APS recharges your battery
faster than conventional chargers
because its three-stage charger pro-
file (Bulk, Absorption and Float) are
optimized, regardless of the type of
battery you use (Wet or Gel).* In addi-
tion, the advanced charging system
protects against over-charge and
over-discharge to ensure a longer
service life from your battery.
* The Absorption and Float levels vary according to
battery type, which can be set to either “Wet” or “Gel”cell.

CHARGING PROFILE
• Voltage Regulation (Select models only)
“VR” APS models regulate incoming AC power by automatically “boosting” or “cutting” the voltage
to keep your equipment running through brownouts and overvoltages
without draining battery
power.
• Load Sharing (Select models only)
Select APS models can be set to limit their own charging functions so they can charge their
batteries at the quickest rate possible without overloading their power input circuits.
• Frequency-Controlled Inverter Output
All APS models feature Frequency-Controlled Inverter Output which allows devices dependent on
AC line frequency (such as computers, VCRs, CD players, tape recorders, clocks and turntables)
to operate properly.
• Circuit Board Protection
A silicone conformal coating safeguards the circuit boards against moisture.
