Motor drive output sine and noise filter with DC link function
The sinus filter "FN 530" converts the output voltage of PWM-controlled inverters into a pure sine wave. It effectively protects the motor. It suppresses common mode noise in the output cables. It has an improvement effect on the overall EMC environment. It prevents damage to motor bearings. It allows the use of unshielded long cables. It enhances the overall reliability of the system. It has obtained international patents. The safety standards comply with UL 1283, CSA 22.2 No. 8 1986, and IEC/EN 60939. For more details, please download the catalog.

basic information
**Features** - Converts the PWM output voltage of the motor drive (normal mode, common mode square wave) to a sine wave. - Reduces motor stress caused by dv/dt noise, overvoltage, motor heating, eddy current losses, and bearing damage. - Prevents noise propagation to neighboring equipment. - Provides the general effects of an LC sine filter. - Allows the use of unshielded long cables without considering radiated noise. - Limits pulse current to ground and leakage current to the earth line. - Facilitates noise countermeasures on the line side. - Enables the use of long cables with low-rated motor drives by reducing losses in the IGBT and cables.
