4 Stage PWM charging: Bulk, Boost. Float, and Equalization
30A charging capacity.
Temperature compensation and correcting the charging and discharging parameters
automatically, improving battery lifetime.
Protection against: reverse current, overcharging, short-circuit and reverse polarity.
Key Features
The Wanderer utilizes Pulse Width Modulation (PWM) technology for battery charging.
Battery charging is a current based process so controlling the current will control the
battery voltage. For the most accurate return of capacity, and for the prevention of
excessive gassing pressure, the battery is required to be controlled by specified
voltage regulation set points for Absorption, Float, and Equalization charging stages.
The charge controller uses automatic duty cycle conversion, creating pulses of current
to charge the battery. The duty cycle is proportional to the difference between the
sensed battery voltage and the specified voltage regulation set point. Once the battery
reached the specified voltage range, pulse current charging mode allows the battery to
react and allows for an acceptable rate of charge for the battery level. The Wanderer
has a 4-stage battery charging algorithm for a rapid, efficient, and safe battery
charging. They include: Bulk Charge, Boost Charge, Float Charge, and Equalization.
