As electrification accelerates across commercial vehicles and mobile machinery, the importance of reliable and efficient auxiliary drives continues to grow. Systems such as HVAC compressors, steering pumps, and brake compressors must operate dependably while fitting into increasingly compact high-voltage architectures.

The RPCS 740-25K from REFUdrive is a high-performance auxiliary inverter designed specifically for these requirements. Delivering up to 25 kVA electrical power, it is ideally suited for applications in electric buses, trucks, municipal vehicles, and off-highway machinery, including agricultural equipment.

Its compact design and high power density make it particularly suitable for installations with limited space. The inverter enables efficient operation of a wide range of auxiliary systems, including HVAC compressors, heat pumps, steering systems, and braking applications.

A key safety feature is the active discharge of the DC link in less than one second, ensuring that no hazardous residual voltage remains after shutdown or disconnection. In addition, the system is engineered for demanding thermal environments and operates up to 65°C coolant temperature without derating, ensuring reliable performance under continuous load.

The RPCS 740-25K supports sensorless vector control, allowing flexible operation with different motor types, with optional encoder integration available. The integrated J1939 interface enables seamless integration into existing vehicle architectures, while AEC-qualified components and development in accordance with ISO 26262 meet automotive industry standards.

Based on the proven REFUdrive dual inverter platform, the RPCS 740-25K combines enhanced performance with significantly reduced installation space, making it a compact and powerful solution for modern electrified auxiliary systems.
