FUJI ELECTRIC FRN0012C2S-7U Variable Frequency Drive 3 Hp 200-230v

Fuji Electric FRN0012C2S-7U variable frequency drive adjusts the frequency and voltage supplied to the motor to allow precise control over motor speed, optimising energy consumption and enhancing operational efficiency. It is ideal for manufacturing processes, HVAC systems and pump applications.

Working Mechanism:

• Variable frequency drives (VFDs) change the incoming alternating current (AC) into direct current (DC) and then use an inverter to convert the DC back into AC power at a different frequency.
• The frequency of the AC power can be adjusted using the inverter's switching rate.
• Users can increase the VFD's frequency to increase the speed of the motor and decrease the frequency to reduce the speed of the motor.

Features:

• Fuji Electric FRN0012C2S-7U variable frequency drive features dynamic torque vector control, allowing precise power calculation based on motor load for optimal performance.
• It comes with an adjustable acceleration and deceleration time ranging from 0 to 3600 seconds, providing flexibility in motor speed control.
• This variable frequency drive offers a broad output frequency range from 0.1 to 400 Hz, catering to diverse industrial applications.
• It is equipped with a brake chopper, ensuring efficient braking capabilities for enhanced control during deceleration.
• It has an open enclosure with an overall depth of 5-1/2 inches and a compact design suitable for various installation environments.
• This variable frequency drive includes built-in protection mechanisms, such as external alarm input, ground fault detection, safeguarding against overcurrent, overheating and other potential issues.

Compatible Accessories:

• Fuji Electric NEMA1-C2-301 AC Drive Kit: This NEMA 1 enclosure protects against dust and incidental contact, 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.

Frequently Asked Questions:

Q. What points should I consider for selecting a variable frequency drive?

A.

• Environment
• Speed range
• Speed variation allowed
• Torque requirements
• Acceleration time
• Duty cycle

Q. Why is a variable frequency drive required for a permanent magnet AC motor?

A. Permanent magnet motors reach full speed / torque almost immediately after actuation. The shock load by a normal power supply can often damage the connected mechanical components. The voltage supplied must be controlled. The VFDs play a big role here by matching motors with their respective power supply. However, users should not run more than 1 motor on a single variable frequency drive (VFD).
