Line Current Harmonics
The product standard EN 61800-3 refers to EN 61000-3-2 which specifies limits for harmonic
current emissions for equipment intended to be connected to public low-voltage distribution
systems.
Low-Voltage Public Supply Network
The limits and requirements of the EN 61000-3-2 apply for equipment with rated current ≤ 16 A. The
ACS 160 is a professional equipment to be used in trades, professions, or industries and is not
intended for sale to the general public.
The ACS 160 with a total rated power greater than 1 kW conforms with EN 61000-3-2. Below 1 kW,
use the following units to comply with class A limits of EN 61000-3-2: ACS163-1K1-3-B, -S, -E, -V
and ACS163-1K6-3-B, -S, -E, -V.
Industrial Networks
If ACS 160 is used in an industrial installation for which the EN 61000-3-2 is not relevant, a
reasonable economical approach which considers the total installation shall be used.
Typically a single low power equipment like ACS 160 does not cause a significant voltage distortion
to network. However, the user shall be aware of the values of the harmonics currents and voltages
occurring within the power supply system before connecting the ACS 160, as well as the internal
impedance of the supply system. The current harmonic levels of the ACS 160 under rated load
conditions are available on request and the assessment procedure given in appendix B of the
EN 61800-3 may be used as guide.
Distribution Networks Isolated from Earth
ACS 160 types 163-xKx-B, S,-E, -V cannot be used in an isolated, or high impedance earthed
industrial distribution networks.
