Electrical Connections 1 4-pin Molex 194280006 (Mates with Molex 194180004 Receptacle) When in AC/DC power supply mode, connect as follows. This product supports one battery output. The 2 pins for Batt+ and 2 pins for Batt-are used to share the current through them. For example, a 10A system will work with Pin 1 and Pin 2 connected but it is recommended to connect all 4 pins (Pins 1&4 joined together to Batt+ and Pins 2&5 to Batt-). Mating Connectors: Mounting_ Mating receptacle assemblies can be ordered from a Molex supplier. Use 6 M8 or #4 bolts to mount the device.

The Battery Charger implements a three-stage charging algorithm, as shown below in Figure 2. The charging process starts from Precharge Stage, then, when the battery voltage reaches a certain point, it switches to the Bulk Charge Stage. Next, the charging process is finalized in the Absorption (Constant Voltage) Stage. The charger can then maintain the battery charge in Float Stage. When the charger is disconnected from the power line, it automatically switches off within one minute by default. This protects the battery from being discharged by the charger electronics. Each stage of the charging...

Ieq Ipc Icv_stop Ifl_stop Vfl Vpc_start Vfl_start Vcv_start Fig.3. Voltage-Current Charging Profile Constant Voltage Mode In Constant Voltage Mode the output voltage of the charger is limited to Vcv and the output current – to Ibc. Once the battery voltage reaches Vcv, the charger is not able to maintain the Ibc constant charging current, so the current gradually drops to Icv_stop and the battery is considered fully charged. Constant Voltage Mode is usually the last charging mode in the charging process. At the end of this mode the charger switches to either Standby or Equalize Mode. Equalize...
