VOLTAGE SURGE AND SPIKE COMPLIANCE MATRIX

These tables show the Voltage Surge and Spike requirements/limits that have been met* by a stand-alone setup comprised of:

- MQME-28-P (or –T) Filter

- MQFL-28-05S DC/DC Converter

- 120W Resistive Load

- Metal Chassis Plane

* 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.
