DC POWER INPUT
The FLEX-6400/FLEX-6600 is designed to operate from a 13.8 volt nominal DC supply
capable of supplying 25 amps of continuous current to the radio.
!
–
This unit must only be operated with the electrical power described in this manual.
NEVER CONNECT THE +13.8VDC POWER CONNECTOR DIRECTLY TO AN AC OUTLET. This
may cause a fire, injury, or electrical shock.
Δ –
The FLEX-6400/FLEX-6600 requires 13.8 VDC @ 25 amps measured at the radio in
order to transmit maximum wattage. Multiple power cable connections between the
power supply and the FLEX-6400/FLEX-6600, a poorly regulated power supply,
undersized power cable and very long power cable lengths will result in a voltage drop,
especially under load. Any voltage deviation from 13.8 VDC will result in lower power
output that the 100W nominal specification.
