The FLEX-1500 can operate off of direct current (DC) power supplies or battery backs. Below are the voltage and amperage specifications when operating the FLEX-1500.
Power Requirements
Receive Amperage @ 13.8
VDC
:
Typical 450
ma
/ maximum 500
ma
Transmit Amperage @ 13.8
VDC
:
Typical 1500
ma
/ maximum 2000
ma
(full power: 5W nominal
CW
keydown)
Recommended Operating Voltage:
13.8
VDC
Minimum Operating Voltage:
8.0
VDC
(receive) / 11.0
VDC
(transmit)
Maximum operating Voltage:
15.2
VDC
NOTE: External power is required when operating the FLEX-1500. The
USB
connector can not provide enough voltage needed to operate the radio. The radio will not power up
if
there isn't a 13.8
VDC
voltage source supplied to the FLEX-1500.
WARNING: Exceeding 15.2
VDC
will damage the FLEX-1500 and void the warranty. Using a laptop power supply that exceeds 15.2
VDC
is not a suitable power source.
Power Supply Requirements
Any power supply using an AC source to produce 13.8
VDC
will need to be well regulated and filtered. The main concern with any power supply is AC ripple. "Wall-warts" with unregulated or unfiltered power output will
NOT
be suitable for transmitting.
Fusing Requirements
The FLEX-1500 has an internal 3 amp ATO type
fuse
on the
PA
board which provide voltage to the TRX board. There is a power diode to ground which will deliberately blow this
fuse
if
the power leads to the radio are reversed. It is recommended that you
fuse
the
VDC
input with at least a 3 amp
fuse
but no higher than 5 amps.
