mHV Primary Box and mHV Auxiliary Box

The mHVPB and mHVAB are innovative modular HV solutions designed respectively for primary and auxiliary power distribution applications. The Primary Box is intended for main loads such as inverters, rheostatic brake circuits and rechargeable energy storage systems, while the Auxiliary Box supports auxiliary loads including OBCs, heaters and cooling fans. Both solutions integrate two versatile base modules – the “In/Out module” and the “Out module” – which can operate independently or be linked together for expanded connections, ensuring maximum flexibility and adaptability. All module combinations can integrate a single interconnected HVIL circuit for enhanced safety. Compatible with a wide range of fuses, contactors and dedicated sensors, the system can be customized according to application requirements while ensuring high resistance to temperature, vibration and harsh environments, with IP67 and IP6K9K protection ratings.
