Battery and capacitor charging

Batteries and capacitors have similar loading requirements, which fit well with the standard functionality of Magna-Power power supplies. When a Magna-Power power supply is connected to a battery or capacitor, the power supply can be programmed for the nominal quiescent voltage and the highest desired charging current.

The power supply, in constant current mode, charges the battery or capacitor at the defined charge current, while the voltage increases with the amount of charge. Once the programmed rated voltage is reached, the Magna-Power supply automatically switches to voltage mode and the charging current drops to zero when charging is complete.
With such loads, we usually work with a protection diode and sense lines to protect the power supply while maintaining an accurate charging voltage.
