FUJI ELECTRIC FRN0020C2S-2U Variable Frequency Drive 5 HP 200-230V

Fuji Electric FRN0020C2S-2U variable frequency drive optimises energy consumption by adjusting the frequency and voltage supplied to the motor, contributing to increased operational efficiency. It is ideal for fans, pumps, conveyors and other machinery where precise motor speed control is essential.

Working Mechanism:

• Variable frequency drives (VFDs) transform incoming alternating current (AC) into direct current (DC) and subsequently utilise an inverter to convert the DC back into AC power, even at a different frequency.
• The adjustment of the AC power frequency is achievable through the inverter's switching rate.
• Users can elevate the VFD's frequency for motor acceleration, consequently increasing motor speed. Conversely, reducing the frequency decelerates the motor, providing control over its speed.

Features:

• Fuji Electric FRN0020C2S-2U variable frequency drive has a dynamic torque vector control for precise power calculation based on motor load.
• It has adjustable acceleration and deceleration times from 0 to 3600 seconds for precise speed control.
• This variable frequency drive offers a wide output frequency range from 0.1 to 400 Hz, accommodating diverse industrial applications.
• It is equipped with a brake chopper for efficient braking during deceleration.
• This variable frequency drive has an open enclosure with an overall compact design (5-1/2 inches) suitable for various installations.
• It has a built-in protection mechanism against external alarm input, ground fault, overcurrent and overheating.
• This variable frequency drive compliance with international standards (CE, EN61800-5-1, UL 508C) ensures reliability and safety.

Compatible Accessories:

• Fuji Electric AC Drive NEMA 1 Kit: This NEMA 1 enclosure prevents dust and incidental contact with the VFD, making it suitable for indoor applications. By seamlessly integrating with the VFD, this kit ensures a streamlined and reliable solution for motor speed control, contributing to efficient and optimised operations in industrial settings.
