|  MIL-C-70942 (AR)
converter located in the M90 data unit and provides all of the
regulated and unregulated voltages for both the antenna and the
data unit.
3.2 Components and assemblies. The components and
assemblies shall comply with all requirements specified on
Drawing 12922112, all associated drawings, and with all
requirements specified in applicable specifications and
standards. Where applicable, the CCA shall meet the requirements
of MIL-F-13926 and MIL-STD-454 as follows :
Dimnensions and tolerances
Inorganic protective surface finishings
b.
Part identification and marking
Workmanship
d.
e.
Soldering electrical connections
3.3 Performance requirements
3.3.1 Input Power. The CCA shall be capable to operate and
withstand minimum 18 VDC to 30 VDC input voltage at 4.5 ADC
maximum input current on the pins indicated in TABLE I.
3.3.2 Output Power. The CCA shall provide the following
output power requirements to the pins indicated on TABLE I.
3.3.2.1 Antenna Power. Power line output for the M90 antenna
unit. The voltage level is unregulated and shall be 26 VDC
minimum when input power (see 3.3.1) is 18.0 VDC and 55 VDC
maximum when input power is 30.0 VDC. Ripple shall be 2Vptp
maximum. This output shall be protected by a fusistor.
3.3.2.2 Internal Power (+12 VDC).
The CCA shall provide +12
+/- 0.6 Volts while output current is 150 mA maximum and ripple
is 200 mVp-p maximum.
3.3.2.3 Internal Power (-12 VDC). The CCA shall provide -12
+/- 0.6 Volts while output current is 150 mA Maximum and ripple
is 200 mVp-p maximum.
3.3.2.4 Internal Power (+5 VDC) . The CCA shall provide +5
+/- 0.25 Volts while output current is 2.0 A maximum and ripple
is 100 mVp-p maximum.
3.3.2.5 Internal Power (-5 VDc). The CCA shall provide -5
+/- 0.5 volts while output current is 30 mA maximum and ripple
is 200 mVp-p maximum.
