The FRN0011C2S-4A is a compact, high-performance variable frequency drive (VFD) from Fuji Electric’s FRENIC-Mini C2 series, designed to control 3-phase, 400V AC motors with a power rating of 3.7 kW (5 HP). Engineered for space-saving installations and reliable torque performance, this drive offers a rich set of features including V/f and dynamic torque vector control, built-in PID functionality, and energy-saving operation.
Ideal for use in conveyors, pumps, fans, mixers, and other light to medium-duty machinery, the FRN0011C2S-4A provides superior speed control, smooth acceleration/deceleration, and precise motor protection. With RS-485 Modbus communication, built-in braking transistor, and global safety certifications, it supports both standalone operation and integration into modern automation systems.
This model is part of Fuji’s next-generation C2 design, offering improved processing speed, extended durability, and seamless backward compatibility with previous FRENIC-Mini models.
