1. INTRODUCTION
SD700 low voltage drives by Power Electronics is the most extensive product family with a power range
from 1.5kW to 2000kW. It has been designed focused on maximum motor care, components durability and
easy maintenance. SD700 portfolio is divided in 3 products series that comply with specific demands and
standards in worldwide installations thanks to its own specific features: SD700, SD700KOMPAKT,
SD700FREEMAQ (SD700FR & SD700FL).
The Freemaq consist of a Notch Filter connected to the input of the SD700 drive in order to reduce the grid
current Harmonic Distortion (THDi). SD700FL drive is not built-in a common passive filter because the grid
impedance modification, the connection of multiple systems or the grid expansion will not reduce the
filtering features and will never cause resonance. Its design is based in the parallel connection of unitary
filter modules. Each module is smartly designed to optimize the space and the internal cooling system. All
of them are managed and controlled without additional hardware by the SD700 drive. SD700 FL is a
compact solution for installations willing to reduce the harmonic distortion. This robust design reduces the
grid current Harmonic Distortion below the 5% as requested by the regulation IEEE519.
