Met by an MQME Filter having the
Transient Suppression and Reverse
Polarity Protection Features
Met by any MQME Filter
* Surge/spike requirements/limits are deemed to have been met as long as transient deviations in the converter’s output voltage
remain within 10% of its initial value.
† For the DEF STAN 61-5 specification:
1) Negative surges require reverse voltage protection circuitry to protect the converter (but not the filter) from a negative input.
This circuitry is included in the MQME-28-T and MQME-28-HT filters but not the MQME-28-P filter.
2) The negative surges may cause the converter to shut down unless additional holdup capacitance is included.
3) Maximum spike voltages are assumed to last <1µs.
