Harmonics
The PCS100 AVC-20 is designed to tolerate disturbances such as voltage and current harmonics in the load or
supply. Excessive distortion can lead to the stressing of components leading to reduction in the lifetime of the
rectifier and inverter modules.
ABB recommends the harmonic contents on the input and the output of the system to meet IEC 61000-2-4 Class
2, THD
V
up to 8%.
Contact the factory for THD
V
> 8% as the lifetime of components may be affected.

Downstream Capacitor Banks
A care must be taken when installing the PCS100 AVC-20 with a capacitor bank downstream of the system. ABB
recommends the capacitor bank to be installed upstream of the PCS100 AVC-20. Contact ABB for more
information.
