2.4.3 'J10' Connector: Optional -48V DC Power Supply
WARNING! Before applying DC power to the unit, make sure the waveguide
output of the amplifier is properly loaded or terminated. Failure to do so could
lead to equipment damage and excessive RF radiation levels.
The 'J10 | DC' prime power input connector is a 4-pin circular connector. A mating connector
(CA3106E2222SB, Comtech PN CN/CA3106E2222SB) is provided. The pinout specifications
for J10 and its mate are shown in Table 2-4.
The power connection for the optional –48V DC supply is located on the power supply itself. A
cap (Comtech PN HW/CAP-5015) is provided with the supply that must be installed on the 'J3 |
AC' Power Connector located on the amplifier.
The prime power input requirements are:
-36 to -72 VDC
Careful consideration must be given to the choice of input wiring because of the
current draw requirements of the HPOD. Wire that is 8 AWG or larger will be
required for most installations.
The total power required from the prime power supply depends on the model used.
Please refer to the respective data sheets.
