INVT GD330-220G/250P-4 frequency converter

INVT GD330 inverter is an energy-saving tool for the fan and water pump industry

1. Variable frequency speed regulation can significantly reduce energy consumption costs and save energy
Fans and pumps are one of the most widely used equipment in the industrial field, and their energy consumption accounts for a large proportion of the total industrial energy consumption. Traditional fan water pumps use baffles or valves to regulate flow, resulting in significant energy waste. The INVT GD330 series frequency converter can automatically adjust the motor speed according to actual needs through variable frequency speed regulation technology, so that the output power of the fan and water pump matches the actual load, thereby achieving significant energy-saving effects. According to actual application data, the energy saving rate of the fan water pump system driven by GD330 frequency converter can reach 20%~50%.

2. Soft start and soft stop extend the service life of equipment
Traditional fan and water pumps use direct starting method, and the starting current can reach 5-7 times the rated current of the motor, which will cause significant impact on the power grid and equipment. The INVT GD330 series frequency converter provides soft start and soft stop functions, which can enable the motor to start and stop smoothly, avoiding the impact of starting current on the power grid and mechanical impact on equipment damage. At the same time, frequency conversion speed regulation reduces mechanical wear of equipment, extends the service life of components such as motors, bearings, valves, etc., and reduces maintenance costs of equipment.

3. Built in PID control for precise flow regulation
The GD330 series frequency converter is equipped with a high-performance PID controller, which can directly receive sensor signals such as pressure, flow rate, and temperature to achieve closed-loop control. Users do not need to configure additional PID controllers, simplifying the system structure and reducing costs. The PID parameter self-tuning function can automatically optimize PID parameters, ensuring that the system has good dynamic response and stability. In applications such as constant pressure water supply and constant temperature control, GD330 can achieve precise flow and pressure regulation, improving the control accuracy and reliability of the system.

4. Multi pump control function meets the demand for large capacity
For large capacity water supply or ventilation systems, multiple water pumps or fans are often required to operate in parallel. The INVT GD330 series frequency converter has built-in multi pump control function, which can achieve automatic switching and rotating operation of multiple water pumps or fans. The frequency converter can automatically control the number of water pumps or fans put into operation according to actual needs, ensuring that the system operates at the optimal efficiency point. At the same time, the rotation operation function can balance the running time of each device and extend the overall service life of the equipment.
