Product Description of FRN220F1S-4NS
The FRN220F1S-4NS Variable Frequency Drive (VFD) is a high-performance industrial motor controller designed to deliver reliable speed regulation, energy savings, and long-term durability in demanding applications. Built for three-phase 380–480 V power systems, this inverter drive efficiently controls AC induction motors by adjusting output frequency and voltage, allowing operators to precisely match motor speed to process requirements. By eliminating unnecessary full-speed operation, the drive significantly reduces electricity consumption, mechanical stress, and maintenance costs.
Engineered for industrial automation, the FRN220F1S-4NS provides smooth acceleration and deceleration with advanced vector control technology. This enables stable torque even at low speeds, making it suitable for heavy-duty equipment such as pumps, conveyors, compressors, mixers, HVAC systems, textile machinery, and production lines. Its intelligent overload protection and thermal management system safeguard both motor and drive, ensuring consistent performance in continuous operation environments.
The unit features an intuitive keypad interface with a digital display for easy parameter configuration and monitoring. Built-in PID control allows precise pressure, flow, or temperature regulation without requiring an external controller. Multiple programmable inputs and outputs provide flexible integration into PLC-based or standalone automation systems. Communication capability supports modern industrial networks, simplifying remote monitoring and system diagnostics.
Designed with compact construction and high-quality internal components, the FRN220F1S-4NS operates reliably in harsh factory conditions. Protective functions such as over-current, over-voltage, under-voltage, overheating, and short-circuit protection increase system safety and equipment lifespan. The drive also incorporates energy-efficient control algorithms that reduce motor noise and vibration while improving operational stability.
Whether upgrading an existing motor control system or designing a new automation line, the FRN220F1S-4NS VFD offers a dependable, energy-efficient, and cost-effective solution. It enhances production efficiency, reduces power consumption, and improves process control—making it an ideal choice for modern industrial facilities seeking improved performance and operational savings.
