Passive harmonic filter DX-PHF

Passive harmonic filters reduce harmonic currents (THDi) so that limits required by standards can be met. They protect the connected electrical power network from the effects of line side harmonics and improve the system's interference immunity. The THDi for the typical operating range can be reduced to less than 8% with a harmonic filter. The value will drop as low as 5% above speeds of 50%.

Active harmonic filter ADF

The state-of-the-art technologies and the complex processes of today's industry place high demands on the power grid, which means that companies are sensitive to numerous factors:

Overheated transformers
Missing standards Comformity / exceeding of default values
Shorter equipment life
Production errors and failures

These problems are caused by numerous electrical disturbances that reduce the quality of the electricity.

Minimised operational downtimes

Common electrical disturbances can be solved with the help of ADF active filters

Safe and Reliable

Reliable protection by complying with the standards.

Main choke DX-LN

Mains choke damps any harmonic distortion (THD) that occurs as well as current spikes and limit inrush currents (the link capacitor's charging current). In addition, it protects the mains rectifier from voltage peaks coming from the supply mains.

(All pole) sine filter DX-SIN3 & DX-SIN3-A

Sine filter is used with variable frequency drives require the frequency to be set to a fixed value within a range of 4 - 8 kHz. The Sine filter DX smooths the output voltage sinusoidally and reduces motor noise through du/dt reduction, thereby increasing the motor insulation’s lifespan. Reduction of the leakage currents to allow better motor performance at improved EMC values.
