March 05, 2024

Bel Fuse Inc. has released its 25 kW liquid-cooled battery charger, the BCN25-1000 Series, for converting 3-phase AC voltage to DC voltage. in medium to heavy-duty vehicles and underground mining applications.

The charger is built from high-quality components and is suitable for industrial trucks, excavators, cranes, and similar equipment where 1,000 VAC is present. The series offers two options: the 350-8 unit with a DC Output 240 – 430 V / 60 A max, and the 700-8 unit with DC Output 480 – 860 V / 30 A max.

The charger’s AC 3-phase input has a range of 800 – 1100 V and an output power up to 25 kW, parallel to 100 kW. This makes it suitable for use as an off-board charger with a typical efficiency of 92%. The charger also features over-temperature, output overvoltage, and overcurrent protections. It is SAE 1455 compliant for harsh environments and includes a J1939 compliant CAN for control and monitoring.

The BCN25-1000 series products meet the requirements of IEC 62368-1 and are water-resistant to IP65 and IP67 ratings.
