MQME-28E-T6

Technical Specification

INPUT OVER VOLTAGE SHUTDOWN: To protect itself from

damage due to sustained excessive power dissipation, the filter will

shut down if the input voltage versus time exceeds the envelope in

Figure E.

During this shutdown, power flow to the load is interrupted and

the filter’s ENABLE OUTPUT pin is pulled LOW. When the input

voltage returns to normal limits (and a Soft-Start Recycle Period has

elapsed), the filter automatically begins a Soft-Start cycle.

All of the surges listed in the VOLTAGE SURGE AND SPIKE

COMPLIANCE MATRIX on page 11 fall below the Figure E envelope.

Only the DEF STAN 61-5 (Part 6)/6 DIT08.B surge exceeds this

envelope. During a DIT08.B surge the filter will shutdown and

then automatically restart once the surge passes. This meets the

requirements of DEF STAN 61-5 (Part 6)/6 at Performance Criterion

C while the DIT08.B test requires only Performance Criterion D.
