3.3.10 Service Conditions - The equipment shall operate satisfactorily
under any of the environmental service conditions or reasonable combination of
these conditions as specified in Specification MIL-E-5400 for Class 2 equipment.
3.3. 10.1 Acoustical Noise - The equipment shall operate satisfactorily
after being subjected to an acoustical noise sound pressure level of 140 dB for
a period of 30 minutes.
3.3.11 Reaction or Warm-Up Time - The time required for the system to
operate shall be kept to a minimum and shall not exceed 1.0 minute under
standard conditions and 1.5 minutes at extreme service conditions.
3.3.12 Input Electrical Power -
3.3.12.1 Operating Power - The equipment shall meet all applicable
requirements of MIL-STD-704 and shall give specified performance when energized
from the following power sources having characteristics and limits as defined in
The power required shall not exceed the specified amounts.
MIL-STD-704.
Alternating Current Power (3-Phase, 4-Wire), 115/200 volts,
Category B, 300 volt-amperes maximum, 200 volt-amperes after 90 seconds.
3.3.12.2 Lighting Power - Input power for lighting shall require not more
than 1.5 amperes at 5 volts. (7.5 volt amperes)
3.3.12.3 Degarded Performance. Degraded performance will be permitted for
voltage transients only as specified in MiL-STD-704 (Category B). System
operation shall return to normal with no resulting damage to the equipment.
3.3.13 Cooling -
3.3.13.1 Thermal Conditions - The system shall operate satisfactorily under
the thermal conditions specified in MIL-E-5400 Class 2.
3.3.13.2 Operating Temperature Check Point - The Electronic Control
Amplifier (ECA) shall have a point accessible on the outer surface of the
equipment for monitoring the temperature(s) of the most critical part(s) inside.
The operating temperature(s) of the part(s) selected for the check point shall
be determined from the evaluation by MIL-T-23103. This check point shall be
clearly marked and shall be incorporated into equipment delivered not later than
45 days after the procuring activity's approval of the cooling design data.
