Bel Fuse launches new liquid-cooled battery charger for underground mining

Bel Fuse Inc, a global manufacturer of products that power, protect and connect electronic circuits, is announcing the release of its BCN25-1000 Series – a 25 kW, liquid-cooled battery charger that converts three-phase AC voltage to DC voltage.

Designed to be a compact solution for medium to heavy duty vehicles and underground mining applications, the new charger is built from the latest, high quality components, Bel Fuse says. Appropriate for industrial trucks, excavators, cranes and the like where 1,000 V AC is present, the series comes in 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 AC 3-phase input has a range of 800-1,100 V and an output power up to 25 kW, parallel to 100 kW, making it suitable for use as an off-board charger with a typical efficiency of 92%, eliminating the need for transformers to lessen overall vehicle weight and cost, according to the company. It features over-temperature, output overvoltage, and overcurrent protections, the charger is SAE 1455 compliant for harsh environments and includes a J1939 compliant CAN for control and monitoring.

BCN25-1000 series products are UL 2202 approved by CSA, IEC certified, and water resistant to IP65 and IP67 ratings, Bel Fuse says.
