Energy saving battery charger

In response to the energy saving and environmental requirements of battery chargers, MEAN WELL has launched the new 220 W battery charger – GC220 series. Possessing very low no load power consumption (<1 W) and up to 93% efficiency, the series offers real energy saving in both standby and active modes. Featuring 2-stage fast charging characteristics, these battery chargers can quickly and efficiently re-supply hungry batteries such as lead-acid, Lithium-Mn and Lithium-Fe types.
Featuring 90–264 VAC full range input, the GC220 series utilises a 2-stage charging curve (constant current and constant voltage) and monitors by detecting the battery voltage. The device can quickly charge a battery using constant current mode when the status is low, and then, the charger automatically switches to constant voltage mode to prevent over charging at the end of the cycle.
Using the standard IEC320-C14 inlet as the input connector, the chargers are equipped with earth ground pin and enclosed by UL 94V-0 rated plastic case. These Class I units are designed to protect users from electrical shock and are especially suitable for charging electric scooters, bicycles and wheelchairs.
With built-in active PFC the GC220 series complies with the harmonic requirement per EN61000-3-2. Other standard functions and features include 2-colour LED indicator for status indication and short circuit, over voltage, and over temperature protection.
