Automatic battery charger for NiCd NiMH Lead and Lead GEL accumulators

MANUAL

Automatic battery charger module for NiCd, NiMH, Lead and Lead GEL accumulators with constant current charger selectable through the supplied shunt resistor (shunt resistors are supplied to obtain constant charge currents 10 - 20 - 50 - 100 - 200 - 500 - 1000 mA).

The current during charging is automatically kept constant, thus allowing a fast and safe recharge of the battery.

To operate correctly, the module must be powered by a ferromagnetic transformer having a voltage higher than at least 10V compared to the operating voltage of the battery to be recharged (maximum 28V). The transformer must also have a maximum output current higher than the battery charge current selected by the shunt resistor.

EXAMPLE

To recharge a 12V NiMH battery with a constant current of 100mA, a transformer with 230V primary and secondary with an output voltage of at least 22V (or 24V) with an output current of at least 100mA (or power> 24V * 100mA = 2 must be chosen , 4VA).

For all constant current rechargeable batteries such as NiCd, NiMH, Lead and Lead GEL batteries.

Absolutely not suitable for recharging LITHIUM batteries.

Transformer not supplied, in our store they are available here: EBAY | MECTRONICA STORE

SPECIFICATIONS

• Supported battery voltages from 1.2V to 18V DC with NiCd NiMH Lead and Lead GEL batteries, not for LITHIUM batteries

• Constant charging current selectable through resistors equipped with shunt (shunt resistors are provided to obtain constant charging currents 10 - 20 - 50 - 100 - 200 - 500 - 1000 mA)

• Requires power supply from ferromagnetic transformer with output voltage always higher by at least 10V compared to the rated voltage of the battery to be recharged up to a maximum of 28V. The transformer must also have a maximum output current higher than the battery charge current selected by the shunt resistor.

• Size approx. 53 x 45 x 21 mm
