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, CEFD PN CN/CA3106E2222SB) is provided. The pinout specifications for J10

The power connection for the optional –48V DC supply is located on the power supply itself. A
cap (CEFD 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.
