2.3.1 Charge Supply

The Charge Modules are non-repairable potted modules. These modules accept a DC input voltage,

monitor battery selection and provide the charging functions for the battery to be charged. The

battery detection circuit, discharge switches, battery charge indicator LEDS and charge circuitry are

all located on these boards. Each module provides the necessary voltage/current parameters to the

battery charge connectors.

2.3.2 Control/Filter Board

The Control/Filter Board accepts the AC and/or DC input power, contains self-resetting circuit

breakers to protect the unit, filters for EMI suppression, a 5V regulator for charger modules and fan,

and functions as the interconnect point between the charge modules and AC to DC Power.

2.3.3 AC to DC Power Supply

The AC to DC Power Module accepts a 115-230 VAC, 50/60 Hz AC input and converts the AC input

to a regulated 25V DC output to the Charge Modules.
