Purpose-built for HVAC, pump, and fan applications where energy savings drive ROI, the Fuji Electric FRN0004E2S-2GB is a FRENIC-Ace (E2) series general-purpose variable frequency drive (VFD) for 230V three-phase applications rated 1 HP / 3.5A (Normal Duty / VT) and 1/2 HP / 3A (Heavy Duty / CT).
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 FRN0004E2S-2GB include HVAC fans and air handlers, conveyor and packaging lines, and mixers and agitators. 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.
