1. Full range of models: GDL series filter options use new models for easy selection. The addition of dv/dt filters and passive harmonic filter completes the range of filter options and provides a one-stop solution for low voltage VFDs.

2. Better matching: GDL series filter options match INVT low voltage VFDs better, making system more reliable and reducing customer system life-cycle costs.

3. Excellent design: The product temperature rise keeps stable thanks to precise thermal loss design, which uses the calculation of iron core loss caused by dv/dt due to output cable distribution capacitance, of magnetic flux density oscillation caused by input ripple current, and of skin effect thermal loss caused by high frequency ripple current.

4. Extra long warranty: A 24-months warranty on GDL series filter options ensures stable and reliable product quality.
