Speed control for three phase 400 VAC motors - 3x 400 VAC supply
The key advantage of a three-phase 400-volt system lies in its higher voltage, which translates to greater power capacity and efficiency. In a three-phase electrical system, the power transmitted is proportional to the square root of three times the line-to-line voltage. Therefore, the higher voltage of a 400-volt system results in increased power delivery compared to a 230-volt system. This higher power capacity is particularly advantageous for industrial applications with larger machinery and heavy loads.
Higher power capacity results in reduced current
The elevated voltage in a three-phase 400-volt system allows for more efficient power transmission over longer distances, minimizing energy losses. It is commonly used in industrial settings where substantial power is required for motors, pumps, and other equipment. Additionally, higher voltage systems often lead to reduced current, which means smaller conductors and less heat dissipation, contributing to improved safety and cost-effectiveness.
Three-phase 400-volt frequency inverters are typically used in industrial and commercial applications. They combine energy efficiency and smooth control over electric motors, allowing precise adjustment of motor speed to match specific requirements. Three-phase 400-volt frequency inverters are well-suited for applications with higher power demands. They are commonly used in industrial machinery, pumps, fans, and other heavy-duty equipment. The enhanced power capacity of three-phase systems ensures that these inverters can effectively handle the requirements of larger and more demanding tasks, making them essential for powering critical equipment in diverse industrial settings.
Different enclosure types
FI-E44 frequency inverters are available in an IP20 enclosure and an IP66 version. The choice between both enclosure types depends on the environmental conditions and the specific application.
IP20 enclosures should be installed in an electric cabinet. They are suitable for indoor environments where the electrical equipment is protected from dust and limited moisture exposure. They are cost-effective and allow for easy access to the internal components for maintenance or adjustments. These inverters are ideal for controlled environments where the risk of water and dust ingress is minimal.
IP66 enclosures offer a higher degree of protection against harsh environmental conditions. They are dust-tight and provide complete protection against powerful water jets, making them suitable for outdoor use or locations with high levels of dust and moisture. The sealed design prevents damage from external elements, ensuring the reliability and longevity of the frequency inverter in challenging settings. However, to ensure sufficient cooling and heat dissipation, it is important to protect them from direct sunlight.
IP66 versions are available with standard analogue and digital inputs or with integrated control switches.
