INVT GD27 frequency converter: calmly responding to the challenges of harsh industrial environments
The industrial production environment is often complex and variable, and factors such as high temperature, high humidity, dust, and power grid fluctuations can have adverse effects on the operation of frequency converters. The INVT GD27 flexible frequency converter fully considers various harsh environmental factors in its design, and through a series of targeted designs, ensures that the product can operate stably and reliably in various harsh environments.
1. Can operate reliably at full load under high temperature of 50 ° C
The ambient temperature in many industrial production workshops is relatively high, especially in summer, where the temperature may exceed 40 ° C. INVT GD27 adopts advanced heat dissipation design and high-quality power devices, which can operate reliably at full load in ambient temperatures ranging from -10 ° C to 50 ° C. Even in a high temperature environment of 50 ° C, there is no need to reduce the rating and it can fully meet the temperature requirements of most industrial applications.
2. Strengthen the coating to resist dust and corrosion
There are a large amount of dust and corrosive gases in the production environment of industries such as metallurgy, mining, and building materials, which can cause serious corrosion to the circuit board of the frequency converter and lead to equipment failure. INVT GD27 adopts a reinforced circuit board coating design, covering the surface of the circuit board with a special three proof paint, which can effectively isolate dust, moisture, and corrosive gases, protect the circuit board from corrosion, and greatly improve the product's adaptability in harsh environments.
3. Wide voltage input adapts to grid fluctuations
The voltage of the power grid in some industrial areas is unstable and fluctuates greatly, which can easily cause damage to the frequency converter. INVT GD27 adopts a wide voltage input design. The input voltage range of single-phase 220V models is 200V~240V, and the input voltage range of three-phase 380V models is 380V~480V, which can adapt to large voltage fluctuations in the power grid. At the same time, the product has an automatic voltage adjustment function, which can automatically maintain a constant output voltage when the grid voltage changes, ensuring stable operation of the motor.
4. Natural cooling models achieve noise free operation
For occasions with high noise requirements, such as laboratories, hospitals, precision machining workshops, etc., traditional air-cooled frequency converters often cannot meet the requirements due to the noise generated by fan operation. The INVT GD27 low-power model adopts natural cooling method, operates without fans, and has no noise pollution at all. The natural cooling design also avoids the risk of failure caused by fan damage, improves product reliability, and is particularly suitable for applications with high requirements for noise and reliability.
