Fuji Electric FRN0003E2S-7GB

An ideal balance of functionality, compactness, and ease of use, the Fuji Electric FRN0003E2S-7GB is a FRENIC-Ace (E2) series general-purpose variable frequency drive (VFD) for 230V three-phase applications.

The FRENIC-Ace (E2) is engineered for energy-intensive applications where variable-torque loads — fans, pumps, and compressors — represent the greatest opportunity for energy savings. Its optimized V/f energy-saving mode automatically reduces output voltage at partial loads, minimizing motor iron losses and cutting energy consumption by up to 30% compared to fixed-speed operation. For tighter speed regulation, the drive supports dynamic torque vector control without an encoder, delivering improved low-speed torque and better transient response.

Standard features include: built-in PID controller, auto-tuning, 8-step multi-speed operation, DC braking, RS-485 Modbus RTU, coast-to-stop and ramp-to-stop modes, and a comprehensive protection suite. Optional fieldbus cards support PROFIBUS-DP, DeviceNet, EtherNet/IP, and CC-Link.

Common applications for the FRN0003E2S-7GB include conveyor and packaging lines, general manufacturing equipment, and centrifugal pumps and water treatment systems. The dual Normal Duty / Heavy Duty rating provides flexibility: Normal Duty (VT) for fans and pumps, Heavy Duty (CT) for conveyors and machinery requiring higher overload capacity.
