mobile and fixed site applications.

DC Power

The MCC-545C requires a power source that can deliver up to 25 amps

of pulsed power (100 msec) out of a +12 VDC to +14VDC power source.

The 25 amp power demand will cause a voltage drop to occur at the

transmitter input, resulting in reduced transmit power, unless the

power cable to the source is sized appropriately. MCC recommends

using two #16 AWG wires for both the power and ground, with a cable

length that does not exceed 10 feet. If a longer cable is required use

#14 AWG. MCC provides a standard 6-foot power cable with lugs for

connecting to a 3/8" battery post.

The power connector pins are shown in Figure 3.6:
