Met by an MQME Filter having the
Transient Suppression and Reverse
Polarity Protection Features
* Requirement is deemed to have been met as long as transient deviations in the converter’s output voltage remain within ±10% of
its initial value.
† For these waveforms at Level 3 and above, an external transient suppressor of sufficient energy rating must placed across the filter’s
input pins to keep the differential transient input voltage below +200V/-50V. Negative polarity waveforms may cause power flow to
the converter to be interrupted long enough to cause a graceful shutdown and restart of the converter. Also, the reverse voltage pro-
tection feature of the -T filter is required to protect the converter (but not the filter) from negative polarity waveform.
** For this waveform at a Level 4 and above, external transient suppressors of sufficient energy rating must be added between the fil-
ter’s input power pins and its case to keep the common-mode transient input voltage below +800V.
