A-A-50764
c. Voltage Stability. The ripple and noise of the output voltage shall not vary more than 1mVRMS with 10mV P-P to 10MHz periodic and random deviation.
d. Temperature Coefficient. The power supply temperature coefficient should be 0.03 percent per degree C.
e. Operating Temperature. The operation temperature of the power supply is -20oC to +50oC rated current to 60oC derated 10% to 71oC derated supply 25%.
f. Storage Temperature: The storage temperature of the power supply is 55oC to +85oC.
g. Collateral Power Output Indicator: A collateral power output indicator shall be provided for monitoring the output voltage and current. This output power indicator shall be required to provide a relative, convenient, monitor to directly track the output power within an accuracy of ± 10 percent.
h. Recovery Time: The recover time for the power supply to go from no-load to within 50 mV of full-load is a maximum of 50 microseconds.
i. Remote Sense: The power supply has terminal sensing to provide correction up to 0.5 volt load lead drop.
2. Type and Size.
a. Design and Construction. Unless otherwise specified herein, the equipment shall comply with the type III design and construction requirements specified in MIL-T-28800.
b. Solid State Construction. The equipment shall be of solid-state modular miniaturized construction. Electron tubes shall not be used, except that high power RF signal production may necessitate the use of electronic vacuum tubes in the output states.
c. Receptacle and Connector Mounting. The connections are provided on barrier strip for jumper wire assembly. The connectors shall comply with MIL-T-28800 3.4.1.5.2.
d. Voltage Adjustment. All output voltage shall be externally adjustable + 10 percent. The ± 15 VDC and the ± 5 VDC shall have a single tracking adjustment for each.
e. Accessibility. The equipment shall be constructed so subassemblies and chassis components can be removed without removing other hardware subassembly, printed circuit card or component.
