MegaWatt S-350-12 30 Amp 9.5-15 Volts Adjustable Ham CB Radio Power Supply 13.8V 12V 33A Peak Not a Clone Real MegaWatt MW

The product delivered a solid voltage and amperage for what I needed. I was running it at 14.6-14.8 volts. System uses about 25amps I saw peaks over 30. The adjustment is very sensitive. The fan is fairly loud when its cranking out 25Amps. Its is pretty quiet when its not doing much. Wish it would sleep if current is lower than .5amp. Its nice to have the extra power for my 12 volt charging/power system. Application is a 12Volt LiFePO battery pack with a DC/DC charger. I swap input from a vehicle starter battery/alternator and this power supply. Works great and I only need a single "expensive" charger.The terminal strip is very tight. 10awg wire barely fit.I wish there was a "table top" model with a simple enclosure for applications where the box in a closet or on a table top.So far I am happy.

Very happy with it, Have a Rostock Max V2, 2 in fact, they are 3D kits, was having issues with power not stable, took some time to catch on to that, but caught power loss from the power supply itself, it is most critical to have no voltage loss at all or the print-head will not do a great job. To make it clear, a 1 volt drop can lower the wattage / heat to the plastic by 20 degrees C. I was having that kind of issue, since computer power supplies have a tendency to drop some voltage at any time, have noticed up to 1.5 volt drip that only cleared once the power supply is reset, did not know that was possible, but saw it happen twice, and lost 2 prints I was working on, and set me back a couple days, luckily, I was wanting a power supply that could go over 12 volts, and found this great deal and very stable power supply. Am replacing my other power supply as soon as my second order gets in, shipping was fast, 3 days, and prints look great again.

The purchase was a speculative buy. There are other power supplies out there that have a big name brand and price. I wanted something of lower cost that would fit my needs and the MegaWatt has not disappointed me. I use it to run a mobile ham radio as a base station (2 meter). There is little noise from the fan and no one has reported any static or interference in my broadcasts. If you are on the fence about a power supply, give this one a try. You will save a ton of money and it will meet your needs (within designed specs for the radio and the power supply). The power supply average about 3-4 hours a day during the week and runs almost non-stop during the weekends. If I needed another power supply, I would not hesitate to buy one of these again.

General class using it to power a Kenwood TS-430 S at a selectively dialed in 13.8 volts.The dial-a-voltage adjuster is VERY sensitive. Took me about 7 minutes of microscopic adjustments with multimeter leads clamped to the output watching it swinging wildly past my target voltage with the teeniest amount of pressure before I finally got my 13.8v target. But it’s a “set it and forget it” item. One time pain, and then perfect function from there in. Delivers what it says, when it says, at the rate it says.Good quality, and clean. No issues on 40m and 20m. Hear CW clearly. No interference. I don’t bounce much past those. But I can say it runs an HF rig, with Signalink data modes too, quite well. :)

My RF transmissions had an annoying problem with the DC power sources' transferring a buzz into the transmitting signal. Ordered the MegaWatt power supply and upon arrival connected the power supply to the transmitter and the transmitting signal was clear and clean. Setting the power supply to my voltage requirement was a breeze. Therefore, I highly recommend the MegaWatt power supply and only wish I had ordered the unit sooner.

1/2017 Update: I bought this in 2014. I was re-arranging my station and saw the power cord that shipped with it sitting in a parts box. I decided to put it on so I could switch unit off if I wasn't using it. This "cheap" power supply has been putting out a constant 13.6V for three years no movement on voltage. I hear no noise on my radio. I do wish the fan was quieter, but I am very happy with my MegaWatt. And it is made in the USA. I would buy another if needed. Still 5 Stars.I found power cord in shipping box. The cord even has a switch on it. I upped my rating to 5 stars, working great after three months.No power cord. Works great after I found and used power cord from old printer.

I love it! It is a nice unit and works as expected and advertised.UPDATE: I bought this unit 3-yrs ago and have used it well for my Amateur Radio 80-Meter band. Over the last 6-months I have been troubled by RFI and recently traced it to this supply. I replaced it with a linear supply and the noise went away. Otherwise, this is a great supply and very reliable and easy to use. Since this supply is a switcher, I have learned that switcher supplies are not recommended by some hams for Amateur Radio.

OK - I have bought the cheapo import power supplies and they are hit and miss but the DC power is always drifting and yes the noise is a bit much so I decided to buy a US made version DC power supply and all I can say is - No Voltage drift at all - no noise, this thing is rock solid and strays that way when fully loaded - no load is needed to start - for a few bucks more this power supply is miles ahead of the cheap imports - also the fan actually works! - Yes I would recommend.
