SIDAC reactors

It is well-known that faults in the supply network can be extremely expensive. Against the background of the liberalization of the energy market and the increasing number of non-linear consumers in the network, supply problems have increased over the last years.
Loads such as automation systems or data processing systems are extremely sensitive to radio interference voltages or deviation of the line voltage from a sine wave.

The availability of these plants is increased with reactors and fil­ters, which are adapted to the requirements of the in the plant optimally. SIDAC reactors and filters are used throughout industry to reduce harmonics and increase the availability of plants and devices.

Single-phase commutating reactors for DC operating mechanisms

Single-phase 4EM commutating reactors for converters are used in double-way circuits from converter assemblies as line reactors into the line-side infeed. They are connected such that alternating current flows through them.

It is their task to limit the line-side voltage dips during commutation of the converter. Also, by limiting the current rise rate di/dt the reactors limit the voltage rise rate du/dt at the thyristors used.

There are various series of reactors in the version Standard (Catalog  60):

u D ~ 2 % for following supply voltage:
230 V AC

u D ~ 4 % for following supply voltage:230 
V AC, 400 V

The figures are based on a frequency f = 50 Hz.

If these do not meet your requirements, versions in Standard modified or customized solutions are available. For more information contact "mdexx GmbH" in Bremen:

Terminal covers for protection against inadvertent contact
with exposed bar connections (DIN VDE 0106 Part 100/EN 50274)

The covers are suitable for all reactors and filters with 1-hole flat connectors. Assignment of the covers to the reactors and filters can take via the connection hole diameter.

If no other information is provided in the technical specifications, touch protection for the backs of hands against unintentional contact with live components can be created according to BGV A2 by using the covers.

The following applies to the versions (see ordering data):
