A VFD Panel controls motor speed in close loop control and Soft Starter current to improve process control, reduce energy consumption, and protect equipment. Variable Frequency Drives provide adjustable speed, torque control, PID regulation, and significant energy savings for variable-torque loads such as pumps, fans, blowers, and HVAC systems. Soft starters reduce inrush current using controlled voltage ramp and current limit, making them ideal for fixed-speed applications that require smooth acceleration and deceleration without mechanical stress. The assembly is designed as per IEC 61439 standards for LV switchgear, while power devices and protection components comply with IEC 60947 to ensure safety and reliability. Options include bypass contactor, braking chopper, EMC filters, dv/dt filters, line reactors, harmonic mitigation, and SCADA connectivity. These panels are widely used in industries such as water treatment, cement, steel, textiles, pharmaceuticals, and commercial buildings where energy efficiency and process accuracy are critical. With intelligent design and robust construction, VFD Panels help industries optimize performance, reduce downtime, extend equipment life, and achieve sustainable operations
