High-Power Precision for Liquid-Cooled Auxiliary Systems

The Sevcon HVLP-20 is the high-capacity variant of the HVLP series, designed for demanding auxiliary loads in 800V electric vehicle architectures. Delivering up to 22kW of continuous power, this liquid-cooled inverter is the industry standard for driving heavy-duty air conditioning compressors, large hydraulic pumps, and thermal management systems in electric buses, trucks, and specialized industrial machinery.

🛡️ Safety & Integration Note

  • High Voltage Safety: Operates at lethal voltages (up to 800V DC). Integrated HVIL (High Voltage Interlock Loop) circuitry is standard to ensure system-wide safety during maintenance and operation.

  • Control Intelligence: Features advanced Flux Vector Control for precise management of both AC Induction and Permanent Magnet (PMAC) motors.

  • Programming: Full parameter access and diagnostics require an IXXAT USB-to-CAN interface and DVT software.

💧 Critical Cooling & Performance Note

  • Liquid Cooling Requirement: To achieve its 22kW rating, the HVLP-20 requires an active liquid cooling circuit (typically a 50/50 water-glycol mix). Ensure a minimum flow rate of 6 L/min for optimal thermal performance and to prevent power derating.

  • Superior Power Density: Compared to the HVLP-10, the HVLP-20 doubles the power output within a similarly rugged footprint, making it ideal for high-duty cycle industrial applications.
