Calex – 4kW DC/DC Isolated Bidirectional Power Converter Modules for E-Mobility (400HBC & 800HBC Series)

The series consists of rugged, highly efficient, 4kW liquid-cooled, bidirectional DC/DC power converters that convert 220-450Vdc (400HBC) / 440-850VdC (800HBC) high side DC input voltage into a 12Vdc or 24Vdc isolated low side voltage, supporting 12/24V battery configurations.

The power converters incorporate a digitally controlled Dual Active Bridge topology with synchronous output rectification to achieve high efficiency and EMI performance. The compact thermally optimized IP6K9K ingress rated enclosure provides a high degree of shock and vibration resistance, suitable for deployment within harsh environments.

Samples are available in May. Full product release is in October.
