These devices have been tailored to meet the demands of the ever-evolving e-mobility industry and deliver 4kW of power, making them suitable for engineers and developers working on Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs).

Providing efficiency, reliability, and ease of integration, the HBC Series simplifies power management for next-generation electric vehicles, making high-voltage power conversion accessible to engineers across the e-mobility sector. Its peak efficiency of 97.2% ensures optimal power transfer between a vehicle’s high-voltage battery and auxiliary systems, boosting both performance and energy efficiency.

With a plug-and-play design, the HBC Series features a J1939 CAN Bus digital interface, allowing easy customisation and seamless integration into existing systems.

Key features of the HBC series

Versatile Power Management: Compatible with both 400V and 800V battery systems, the HBC Series offers flexible input ranges (220-450Vdc or 440-875Vdc) and provides a 12V or 24V output for auxiliary system support.

Bi-Directional Power Flow: Seamlessly handles power conversion in both directions, managing high-voltage and low-voltage systems with ease.

Monitoring & Control: Equipped with a built-in CAN Bus interface, engineers can monitor system data, adjust settings, and control key functions - no need for in-depth power conversion expertise.

Superior Efficiency & Reliability: Achieves up to 97.2% efficiency, minimising energy waste and heat, while its liquid-cooled design ensures stable performance, even in harsh environments.

The HBC Series will help to enhance projects for engineers developing EVs, HEVs, or any application that requires high-voltage power conversion for auxiliary systems. It’s especially valuable for those working on battery management and system optimisation without specialised knowledge of power electronics.
