Harmonics

Suppressing high-frequently reverse currents is explained in the EN 61000-3-2 standard.

This standard is valid since January 1st, 2001, and is based on the predecessor standard

EN 60555-2. EN 61000-3-2 is part of the basic EMC standard EN 61000-6-3 (noise

emission) (see also section 3.18, "Harmonics").

This standard contains limit values for harmonic currents, which are determined with

reference to the input network current. It is valid for all electrical devices that are intended

for use on the public low-voltage network. The standard is only valid for 75 W to 1000 W

devices used within the European Union.

With regard to noise emission, primary-switched mode QUINT POWER, MINI POWER and

STEP POWER devices may be used in domestic applications as well as in industrial

applications. Concerning noise emission this means that the limit values for harmonic

currents must not be exceeded. A decisive factor for noise immunity is that interferences

of any kind do not affect the function of a power supply unit.

3.12

Pollution Degree

Depending on their load and use, power supply units are exposed to certain environmental

influences such as dust, humidity and aggressive substances. The resistance of an

electrotechnical component to these influences is described by the pollution degree. The

pollution degree is divided into classes from 1 through 4. For industrial use, power supply

units with class 2 have proved to be effective. Non-conducting pollution may occur with

class 2 devices. In the event of condensation, this pollution may temporarily become

conductive.

Fields of application for class 2 devices are, for example, the domestic, sales and office

areas, precision engineering workshops etc.

If class 2 power supply units are to be used in applications in which a higher degree of

pollution must be expected, the power supply units are installed in a distribution cabinet

with an appropriate degree of protection (see section 2.1, "Mechanical Structure").
