Note
Power losses are given for nominal supply voltage, default switching frequency, and rated
output current. Changing these factors may result in increased power losses.
Harmonic currents
In order that you may operate a V20 230 V converter in the first environment, Category C2,
you must observe the limit values for harmonic currents. V20 converters are not designed for
general use in residential areas. They are professional equipment for use in trades,
professions or industries and are not intended for sale to the general public. Please also
observe and adhere to the following notes and instructions when operating a V20 230 V
converter.
Note
Observing the limit values for harmonic currents
With respect to the compliance with limits for harmonic currents, the EMC product standard
EN 61800-3 for V20 230 V converters refers to compliance with standards EN 61000-3-2
and EN 61000-3-12.
Note
For unrestricted operation on public low-voltage grids further EMC measures may be
necessary. Compliance with harmonic emission limits (IEC 61000-3-12 and IEC 61000-3-2)
cannot be guaranteed.
● V20 230 V converters with the rated output power ≤1 kW and rated input current ≤ 16 A:
It cannot be guaranteed that the limit values are complied with EN 61000-3-2. The
installation person/company or company operating the professionally used device must
obtain authorization from the grid operator to connect the device regarding the harmonic
currents. For more information about typical harmonic currents of V20 230 V converters,
see the following table.
● V20 230 V converters with the rated output power > 1 kW and rated input current ≤ 16 A:
These devices are not subject to any limit values, and as a consequence can be
connected to the public low-voltage grid without any prior consultation.
● V20 230 V converters with the rated input current > 16 A and ≤ 75 A:
It cannot be guaranteed that the limit values are complied with EN 61000-3-12. The
installation person/company or company operating the professionally used device must
obtain authorization from the grid operator to connect the device regarding the harmonic
currents. For more information about typical harmonic currents of V20 230 V converters,
see the following table.
