MegaWatt Power Supply for Ham Radio CB Radio set up

[@radio429]

Just an additional observation for people who use these: 14.4 volts is generally the max an alternator charges a vehicle at these days. Therefore I understand wanting to set it at that point. It should be noted that most equipment is usually specified at 13.8 volts for the unit to operate as advertised, some vary a little on their spec sheet. A lot of folks buy these and set them to about 15 volts when they are using them with an external "CB" type RF amplifier as most will easily handle that voltage and it also helps keep the maximum peak power available out of the amp. These are great working power supplies and are as about RF noise free as you will find out there! I highly recommend them. The Duracomm's and Iota branded ones appear to be nice and clean also from my past experience with them. Have fun!!

Your vehicle charges at approx 14.3 to 15 volts setting these to 14.3 or 14.5 is fine.

Nice lesson I just ordered mine from Amazon... Thanks

[@adonikam1]

Late comment but EXCELLENT VIDEO THANK YOU!!

[@joemason9187]

Nice vid

same is sold as MeanWell. Their model number are --

[@ValenteEspinosa]

Loved your rack where you placed the osciloscope

[@CinematicTouchProductions]

Thank you very much for this video, I cut open my three prong computer cable to connect to my MEAN WELL switching power supply similar to the one you have here and my three wires inside are color BLUE BROWN AND GREEN/YELLOW STRIPE, so which one is ground, neutral and positive?

[@DAVE_WHITE]

Use your ohms meter and figure it out.

[@CinematicTouchProductions]

@@DAVE_WHITE I did figure it out

[@aaronparris8591]

Great video. Can you make a video to show how to wire 4 of those together?

[@DAVE_WHITE]

megawatt has one but to make more then one you only can set them to exactly 14 volts not 14.4

[@DAVE_WHITE]

here is their video kzbin.info/www/bejne/e4qomouvlLmiipI

[@AlexCausey]

I use one of these for my Icom ic706..!

[@xXxWoNdEreR7XxX]

@@DAVE_WHITE could I ask you a question....what size potentiometer is that your turning my friend that's disabled broke his and wants me to replace it but it's gone off the board..any help would be greatly appreciated'

[@seanrose1252]

Thanks, Dave. I bought one of these and I'm getting ready to wire it up, but the terminals on the radio wire are too large for the small connector on the power supply. I can cut them and crimp on some smaller, forked terminal ends, but I'm concerned I'm downsizing the ends too much. I skipped circuits in college and I don't understand why the wires and terminals are so much larger than the computer cord wire that's supplying the power. Can you include a pic of the radio power lines actually connected to the power supply, or simply comment on connectors. Thanks much.

[@DAVE_WHITE]

Ac and dc require different wires. Dc needs bigger multi stranded wire to carry current whereas ac can use thinner lower strand or even solid conductors.

What do you think of the 700-12 50amp thinking of getting one for my 98vhp

[@miguelsalami]

The Megawatt S-700-12 runs my 98VHP perfect👍👍

[@KevinModz65]

I just ordered 2 of the 50 amp and want to run them in parallels. I have a new Delta Electronics 60 amp power supply on a Texas Star DX500 and it all dims when I key up, I’m hoping this will remedy it

[@miguelsalami]

@@DAVE_WHITE 100 amps should run a TS500 no problem they draw about 65 amps of current @ 13.8 volts.

[@ilfilmsofficialchannel8085]

hello I have the same power supply, or rather the voltage from this series of power supplies is adjusted to 13.8v, the power supply works ok, it works fine with the president lincoln1 but when he charges the smartphone listen to the interference power supply, did you have it like yes say please how to eliminate this problem from disruptions ..

[@DAVE_WHITE]

contact john @ megawatt off of the website he will probably have solutions. you can also try ferrite beads on the cell phone cable?

[@carolinapirate2830]

Are the MegaWatt power supplies noisy (rf noise)? My Radio Shack 25 amp switching power supply is very noisy on my HF receive radios. It's noisy even on the HF radio sitting on the next desk connected to a different analog power supply.

[@johnbigbooty]

Pirate, I have a MegaWatt 36 Amp and also an Astron VS-50M (50 Amp) Linear Power Supply. I've been impressed with the MegaWatt. Works great.

[@DAVE_WHITE]

megawatt on his site has a video of a noise test that was done comparing these to the cheap knock offs..

[@jackrider57]

You never see a review where Megawatt vs. Meanwell,that would be interesting! Maybe same company.

[@eddiedowning2571]

Do they come from the factory at 12volts or they have to be turn up

[@DAVE_WHITE]

the video shows it from the factory so yes you have to adjust it

[@royrodriguez8856]

THANX 👍QUESTION ANOTHER YOURUBER PLAED A JUMPER CABLE ???Why?

[@paulshockieuk2651]

13.8 people your equipment will last longer

[@ejbeekeeper4360]

Hi Dave, in a video from Fred in the Shed I read some comments about these power supplies saying they can blow up your rig. What's your experience? kzbin.info/www/bejne/qKrdlJ-vd7acrqs

[@DAVE_WHITE]

I have 5 of them here total since 2016 nothing has blown up, fred might be sniffing some glue
