Connecting An External Dc Power Supply; Connecting The Antenna Tuner - Icom IC-7300 Basic Manual

Connecting an external DC power supply

Confirm that the transceiver is OFF before connecting
the DC power cable.
L We recommend using Icom's optional PS-126
(DC 13.8 V/25 A) power supply.
L When connecting a non-Icom DC power cable, the
transceiver needs:
• DC 13.8 V (Capacity: At least 21 Amps)
• a power supply with an over current protective line and
low voltage fluctuation or ripple.
