MIL-PRF-19500/483D
4.5.4 Operational thermal cycling. This test shall be performed by connecting a three phase 60 Hz sine wave input
of 10 to 20 V rms to the ac terminals of the bridge. The resistive load or input voltage shall be made variable in order
to maintain a rated bridge output current of 25 A dc. Bridge case temperature shall be maintained at +55C except
during the cooling cycle when case temperature shall be permitted to drop 20C maximum. Life-test duration shall be
2,000 cycles with a heating time of 8 minutes, +2, -0 minutes and a cooling time 2 minutes.
4.5.5 Pulse measurements. Conditions for pulse measurements shall be as specified in section 4 of
MIL-STD-750.
