Mean Well Introduces New AC-DC Battery Charger Series

Mean Well introduced a new intelligent ac-dc battery charger series – PB-1000 – a 1000W charger for lead-acid batteries. Featuring user selectable 2-stage/8-stage charging characteristics, it is claimed that this microprocessor controlled intelligent charger can quickly and efficiently charge batteries or, using a more complete charging curve, store more energy into the battery banks. There are 2 battery banks that can be connected to the PB-1000 at the same time. The designed charging serial will switch the charging current between two battery banks automatically to ensure both banks are fully charged and maintain them at a suitable energy capacity level all the times.

To effectively extend the lifetime of batteries and reduce maintenance time, the PB-1000 also possesses a built-in temperature compensation circuit. By connecting the NTC sensor coming along with the charger unit to the body or ambient of the batteries, the output voltage of the charger will be adjusted accordingly based on the temperature. Featuring a built-in active PFC function, the PB-1000 can comply with the harmonic requirement per EN61000-3-2. Other standard function/features include an IEC320-C14 – 3 pole ac inlet, power ON/OFF switch with light indicator, remote ON/OFF control, fan ON/OFF control, reverse polarity, short circuit, over-voltage, and over temperature protections. Suitable applications include home appliance, solar power system, security system, UPS system, electrical wheelchair, leisure vehicle and vessel applications that may use lead-acid batteries as the power source or back-up system.
