4.1.1 DC Power
The MRC-565 requires a power source that can deliver up to 20 amps of pulsed power (100
msec) from a +12 V
DC
to +16V
DC
power source.
The 20 amp current draw 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. MRC
recommends using two #16 AWG wires for both the power and ground and a cable length that
does not exceed 10 feet. If a longer cable is required, use #14 AWG. MRC provides a standard
6 foot power cable with lugs for connecting to a 3/8" battery post (Part No. 14001350-01).The
power connector pins are shown in Figure 6 as follows:
