Frequently Asked Questions

What is the primary benefit of the Active Front End (AFE) technology in this Danfoss inverter?

The AFE technology actively manages harmonic distortion, feeding it back to the grid. This ensures near-unity power factor, reducing energy waste.

It also significantly lowers harmonic pollution on the power supply. This compliance is crucial for many industrial sites and grid operators.

This leads to reduced electricity bills and avoids potential penalties for poor power quality, enhancing overall cost-effectiveness.

How does the IP55 rating impact the installation and application of the FC-302P37KT5E55H2XGCXXXSXXXXAXBXCXXXXDX?

The IP55 rating signifies protection against dust and low-pressure water jets from any direction. This makes it suitable for challenging environments.

It allows for installation in areas prone to dust, moisture, or light splashing, common in manufacturing plants or outdoor installations.

However, it does not protect against high-pressure jets or submersion, so careful placement is still necessary.
