Fuji Electric FRN0004E2S-4GB variable frequency drive (VFD) is used in industrial automation to control the speed and torque of electric motors. Its applications include conveyor systems, pumps, fans and HVAC equipment, where precise motor control is necessary to optimise performance and energy efficiency.
Working Mechanism:
- The VFD receives AC power and a rectifier converts it to DC power, preparing it for processing.
- The DC flows through a DC bus with capacitors that smooth the DC voltage, ensuring stability.
- An inverter then converts the DC back into AC, using techniques like Pulse Width Modulation (PWM) to adjust the frequency and voltage of the output.
- The modified AC output controls the motor speed by varying the frequency of the electricity supplied to the motor.
- Sensors monitor motor performance and provide feedback to the VFD, allowing real-time adjustments to maintain desired operation under varying load conditions.
Features:
- It features programmable start / stop control, enabling customisation of motor start-up and shutdown sequences.
- This variable frequency drive accepts remote contact input signals facilitating seamless integration with external control systems for streamlined operation.
- It comes with a remote keypad control for a convenient user interface that can be operated from a distance.
- This VFD is equipped with a brake choppe for rapidly decelerating the load by effectively dissipating the motor's kinetic energy.
