Description
The FME270 Series EMI filters are specifically designed to reduce the reflected input ripple current of Interpoint’s high frequency DC/DC converters. FME270 filters minimize electromagnetic interference (EMI) for the MHP270 Series of converters. These filters are intended for use in 270 volt applications which must meet MIL-STD-461C CE03 levels of conducted emissions. One filter can be used with multiple converters up to the rated output current of the filter.
Place the filter as close as possible to the converter for optimum performance. The baseplates of the filter and the converter should be connected with the shortest and widest possible conductors.
Transients
A transient of -500 to +500 V for up to 100 ms will not damage the filter but will be passed on to the converter:
Input Ripple and EMI
Switching DC/DC converters naturally generate two noise components on the power input line: differential noise and common mode noise. Input ripple current refers to both of these components. Differential noise occurs between the positive input and input common. Most Interpoint converters have an input filter that reduces differential noise……
