FUJI ELECTRIC

Fuji Electric, established in 1923 and headquartered in Tokyo, Japan, is a global manufacturer of industrial electrical and electronic equipment. The company's product portfolio includes variable frequency drives (VFDs), power semiconductors, instrumentation, and industrial control systems. For plant engineers and maintenance managers, Fuji Electric is known for its FRENIC series of VFDs, which are designed for motor speed control in applications ranging from pumps and fans to conveyors and compressors. The FRENIC Ace and FRENIC Mega families, stocked by 3G Electric, offer three-phase output configurations with power ratings from 3 hp to 40 hp, supporting single/three-phase or three-phase input. These drives feature compact or heat sink styles, with IP20 enclosures available on certain models, and are built to operate in industrial environments with ambient temperature ranges typically from -10°C to 50°C. Fuji Electric also supplies regenerative blower accessories, such as the VRV50 vacuum relief valve, which has a preset limit of 156 in wc and a 2-inch outside diameter, designed to protect blowers from overpressure or vacuum conditions. 3G Electric provides global logistics support for these products, offering datasheets and technical specifications to assist with selection and integration. The drives are suitable for applications requiring precise speed regulation, energy savings, and reduced mechanical stress on motors. Fuji Electric's VFDs incorporate features like automatic torque boost, slip compensation, and multiple V/f patterns, making them adaptable to various load types. The company's long history in power electronics and automation ensures that its products meet international standards for safety and performance, though specific certifications should be verified per model. 3G Electric's inventory includes over 300 SKUs of Fuji Electric VFDs and blower components, enabling procurement specialists to source replacements or new installations with consistent availability.

Frequently asked questions

Common questions about FUJI ELECTRIC from 3G Electric.

What are the key differences between the Fuji FRENIC Ace and FRENIC Mega VFD series?

The FRENIC Ace series is designed for general-purpose applications with a focus on compact size and heat sink cooling, suitable for environments where space is limited. The FRENIC Mega series offers a compact/heat sink style and supports both single/three-phase and three-phase input configurations, with power ratings up to 40 hp. The Mega series typically includes more advanced control features like vector control and built-in PLC functionality, while the Ace series emphasizes simplicity and cost-effectiveness for standard motor speed control.

What input and output phase configurations are available for Fuji FRENIC drives from 3G Electric?

Fuji FRENIC drives stocked by 3G Electric are available in two input configurations: single/three-phase input (e.g., FRN0032G2S-2GU) and three-phase input (e.g., FRN0059E2S-4GB). All models provide three-phase output. This allows flexibility for facilities with different power supply types, such as single-phase for smaller installations or three-phase for industrial settings.

What is the purpose of the Fuji Electric VRV50 blower relief valve, and how is it installed?

The VRV50 is a vacuum relief valve designed for regenerative blowers, with a preset limit of 156 in wc and a 2-inch outside diameter. It protects the blower from excessive vacuum or pressure by venting air when the preset limit is exceeded. Installation involves connecting the valve to the blower's inlet or outlet piping, ensuring proper orientation for vacuum relief. It is typically used in pneumatic conveying or aeration systems.

What enclosure ratings are available for Fuji FRENIC VFDs from 3G Electric?

Fuji FRENIC drives from 3G Electric are available with IP20 enclosure ratings on certain models, such as the FRN0115G2S-2GU. IP20 provides protection against solid objects larger than 12.5 mm (e.g., fingers) but no protection against water ingress. For environments with dust or moisture, additional enclosures or panel mounting may be required. Other models may have different ratings; check the datasheet for specific IP levels.

Can Fuji FRENIC VFDs be used for pump and fan applications to save energy?

Yes, Fuji FRENIC VFDs are commonly used for pump and fan applications to reduce energy consumption by adjusting motor speed to match load demand. Features like automatic torque boost and slip compensation help maintain efficiency across varying speeds. The drives support multiple V/f patterns and PID control, making them suitable for constant pressure or flow regulation in HVAC and water treatment systems.
