FLT: Filter Module

The internal operation of DC/DC converters utilizes pulsed voltages and currents, which can generate broad-spectrum noise that results in electromagnetic emissions. To ease the task of meeting International Standards that limit emissions, GE offers a range of input filter modules with current ratings of 5, 7, 10, 12 and 20 A. One properly sized filter module can be used with one or multiple DC-DC converter modules.

Our filter modules reduce the levels of conducted common-mode and differential-mode noise, providing high insertion loss throughout the frequency range regulated by such bodies as the International Special Committee on Radio Interference (CISPR) and the U.S. Federal Communications Commission (FCC). All of our filter modules are rated for differential input voltages up to 75 V DC and common-mode input voltages up to 1500 V DC.
