AC/DC battery charger

10 November 2010 Power Electronics / Power Management

After launching the GC160 (160 W) and GC220 (218 W) series, Mean Well has further expanded its AC/DC battery charger line with the introduction of the 120 W GC120. With no-load power consumption below 0,5 W and up to 91% efficiency, the units save energy in both standby and active modes.

The chargers are suitable for all types of batteries, including lead-acid, Lithium-Mn (LiMnO₂), Lithium-Fe (LiFePO₄) and sealed lead-acid gel.

The GC120 series employs a two-stage charging curve (constant current and constant voltage) and can monitor battery capacity by detecting the battery voltage. The device can quickly charge the battery in constant current mode in a low battery capacity status. Then, when the battery bank becomes full, the charger can automatically transition to constant voltage mode with low charging current to avoid lifetime reduction caused by over-charging.

Using the standard IEC320-C14 inlet as the input connector, the chargers are equipped with an Earth ground pin and enclosed by a UL 94 V-0 rated plastic case. These Class I units can effectively protect users from electrical shock and are especially suitable for charging electric scooters, electric bikes and electric wheelchair. Featuring 85-264 V a.c. full range input and built-in active PFC function, the GC120 series can comply with the harmonic requirement per EN61000-3-2. Other standard functions include two-colour LED indicators for charging status, short circuit, over-voltage and over-temperature protections. The chargers have been awarded global safety/EMC certificates per UL, TUV, CB, FCC and CE.
