- SynQor®
When it comes to operating in a railway environment, SynQor’s solutions are best-in-class. Their rail converter products have high performance and zero derating, without the use of heat sinks and fans.
They are also composed of one or more switching stages containing both pulsed voltages and currents, which generate a broad noise spectrum resulting in electromagnetic interference (EMI).
The RailQor series of EMI filters brings SynQor’s field-proven technology and manufacturing expertise to the industrial power applications marketplace with the focus of reducing undesired noise.
