RNHV Series Medium-Voltage Variable Frequency Drive
The RNHV series intelligent medium-voltage variable frequency drive utilizes power unit series connection technology to directly output 6kV/10kV voltage, representing a reliable voltage source medium voltage VFD solution.
Engineered for high reliability, user-friendly operation, and exceptional performance, this drive effectively meets energy-saving speed control requirements for industrial fans, pumps, and compressors, enhancing production efficiency and processes.
Each system undergoes rigorous inspection and performance testing before shipment, ensuring consistent quality and reliable performance for every equipment unit delivered.
Integrated Design & Installation
Featuring an integrated design concept that includes transformer cabinets, power cabinets, control cabinets, and optional medium-voltage switchgear with bypass cabinet, the RNHV series minimizes installation complexity. Users simply connect medium-voltage input/output cables, low-voltage control power supply, and control signal lines for rapid commissioning.
With integrated transportation and unilateral maintenance capabilities, the RNHV series offers convenient on-site installation, maintenance, and commissioning. The system incorporates metallized film DC support capacitors and internal mechanical bypass modules, providing higher reliability, maintenance-free operation, and extended lifespan compared to traditional electrolytic capacitors.
