Power Supply

For the RCI-2970DX, a recommended power supply is the Astron RS-20A or equivalent.
CAUTION: Please be aware some "switching power supplies" can generate noise that will get into the receiver.

there you go. so the answer is yes. set the voltage between 13.8 and 14.2. i wouldnt go any higher than 14.2.

well while I agree that my astron 20A should run my 2970dx ...it doe not...
I use the astron 50A and it does fine...

a good 20 amp power supply should do the job..
however i always ran mine on a Iota 45 amp supply
i do not recomend setting supply to 14 volts
when i used mine i set to 13.4
(even though manual called for 13.8 volt setting...my iota supply was only able to be set to 13.4 or 14.2 volts)
if you are using a 30 amp or better GOOD QUALITY switching power supply...then set it to work at 13.8 volts
(setting it higher or lower can cause problems for your 2970DX even though i ran mine on 13.4...i figured 13.4 was better then 14.2 volts)
anyways
any good power supply 30 amps or more will work fine
if you use a stronger supply it is ok
for radio will only draw what it can use
but to have not enough power can indeed cause problems for both radio and supply and could actually be a fire hazard if used regularly (although would have to be a bad power supply to be so dangerous)

i also had a 2970 and a 25amp pyrmid p/s and it did the
but not very good lights dimmed when transmitting
so answer your question yes it will be fine to run a 50amp p/s
on it.i wouldnt exceed 13.8 volts.

Yes, that's 3100 degrees F. Nine yrs of hard work.
undertaker,
It kinda depends on how the radio has been tuned.
I have had 6 of these radio's over the years and they do run just fine on a 36 amp supply. But they will tax a 25 amp for sure.
I run mine on 14.1 and a couple of the radio's that I've had, would put a strain on the 36. Have seen a couple of the radio's pull down 26 amps.
So YES to question...52 amp supply will work just fine.

Power Connection
The transceiver operates off of any 12 to 13.8 VDC source. Beware of
voltage drops caused by operating from Cigarette Lighter Plugs or long
DC wire runs. Sometimes it is best to connect direct to the battery for
best RF output and Tx audio quality
If an AC power supply is used with your radio, it must be regulated and
rated for at least 7 Amps continuous for the RCI-2950DX and 20 Amps
continuous for the RCI-2970DX-150. Low voltage while under load will
cause reduced receiver gain and low transmitter output with possible
distortion and splatter.
Voltage above 15 VDC will damage the unit. Be sure to check the
source voltage before connecting the power cord.

a 20 amp supply should be all that is needed
often though the radio will pull more then 20 amp is designed to deal with
is best to get a 30 amp or higher (Good Quality) power supply
i use a 45 amp
again if supply has more continual power ability then is needed
then radio will only draw what it needs
while the extra power not used is simply a less stressed power supply
oh and the 52 supply should indeed be plenty

i think ranger says 20 amps based on a stock factory radio. so once its tuned up you probly would need mroe than 20 but 50 amps should be more than enough.
yes ranger states 20 amp draw
but ranger is not continually acurate
i have found even bare bone stock can need more then 20 amps

ditto me to ive owned 3 of them only 1 did fair at best with only 20amps the radio was bare stock and lights still dimmedKingCobra_CDX882 said:
