Three-phase static switching units for 6-terminal capacitors

Description

The static switching modules of the EM Series are the basic building block for the construction of static capacitor banks for Power factor correction purposes. These capacitor banks use thyristors instead of the classic contactors for the connection of each large group of capacitors and they are ideal in installations where the leakage current suffers quick and large fluctuations (load changes in intervals that can range from split seconds to 8 or 10 seconds).

Applications

The static switching units of the EM Series have been designed to connect and disconnect capacitors in milliseconds. They can be used to build capacitors with various steps, or for the individual compensation of a load that must be compensated instantly due to connection / disconnection deficiencies, for example, in welding units, cranes, lifts, etc.
