MIL-P-48606B(AR)
3.3.4 Humidity (non­operating)
The power supply assembly
shall meet the requirements of 3.4 and 3.5 after exposure to an
atmosphere with a relative humidity in excess of 95 percent for a
period of 10 days.
3.3.5 Immersion (non-operating)
The power supply assembly
shall meet the requirements of 3.4 and 3.5 and shall have no
evidence of water penetration within the case after being immersed
in water and subjected to a positive pressure equivalent to 3 head-
feet of water (approximately 1.3 psi) for a period of two hours.
The power supply assembly shall be immersed with its case closed, an
equivalent dummy load, and a sealed plug in place of the pressure
release valve.
3.4 Electrical.  Each conductor shall be electrically
continuous as specified on the schematic diagram of the power supply
assembly.
3.5 Performance.
3.5.1 Initial voltage adjustments.  The power supply assembly
shall produce the following output voltages and currents as shown in
Table I (Power supply output voltage) when operating from a primary
power source of 24 + 1 Vdc.
TABLE 1.
Power supply output voltages.

NOTE:
The voltages shall be initially adjusted to the requirements
of Table I and shall not require further adjustment during
any subsequent performance and/or environmental tests unless
specifically indicated.
3.5.2
Power drain.The power supply assembly shall require no
more than
14 amps (steady state) from the primary power source when
operating
under loads that produce the maximum load currents
specified
in Table II and minimum primary input voltage of 18.1 +
0.1 Vdc.
