TRANSOMIK U2 Frequenzumrichter sind für den Anlauf, das Bremsen, die Drehzahlverstellung, das Regeln und Positionieren von Drehstrommotoren ausgelegt.
TRANSOMIK U2 Frequenzumrichter arbeiten nach dem Prinzip eines Umrichters mit fester Zwischenkreisspannung und eines Wechselrichters mit Pulsbreitenmodulation.
Die feste Zwischenkreisspannung wird mit einem 2Q-Drehstromgleichrichter erzeugt. Eine nachgeschaltete Drehstrom-Brückenschaltung aus IGBT-Transistoren, wandelt wiederum die Gleichspannung in ein Dreiphasensystem mit einstellbarer Frequenz und Spannung um.
Aufgrund dieser Konfiguration wird eine 4Q-Antriebsregelung möglich, ähnlich der Eigenschaft von Gleichstromantrieben, jedoch ohne deren Nachteile.
TRANSOMIK U2 ist deshalb auch für dynamische Anwendungen geeignet.
Beim Bremsen wird die Antriebsenergie ins Netz zurückgespeist. Ein Brems-Chopper wie bei normalen Umrichtern üblich, ist nicht mehr notwendig.

The RM 220E regulator is an electronic speed variator for the MINI MOTOR single-phase asynchronous motor of the ACR / ACER / PAR / PAER / MCR / MCER series. Speed variation is obtained by varying the power supply voltage to the motor at the right moment. The retroaction control makes it possible to maintain a constant rotation speed of the motor in line with the variation of the load applied. Speed regulation is obtained by means of a potentiometer fitted on the front panel of the unit, and 4 incorporated trimmers are used for regulating: The acceleration and deceleration ramps, the response time and maximum speed, and master or slave selection. This speed regulator can be supplied in the RM 220E panel version with the possibility of inserting an ID speed indicator as an option. It is also available in the open version RM 220E/G for electrical board or cabinet fitting. The RM 220E regulator conforms to tests prescribed by product standard CEI EN 61800-3 dated 09/96 and has been designed to operate in industrial environments. It is not therefore suitable for use on low-voltage public networks supplying power to homes.
