Product Description

MFJ 4230MV 30 Amp Switching Power Supply

This is the world’s most compact switching power supply that also has a meter and adjustable voltage control.

Just 5" W x 2 ½" H x 6" D, it weighs only 3 lbs. -- it is the perfect pack-n-go power supply for field day, DXpeditions, camping, hiking or to pack for your next business trip or vacation to some far away place.

MFJ-4230MV gives you 25 Amps continuously or 30 Amps surge at 13.8 VDC. The voltage is front-panel adjustable from 4 to 16 Volts. MFJ-4230MV also has a selectable input voltage: choose from 120 or 240 VAC at 47 - 63 Hz.

A simple front-panel push-button switch lets you choose either Ampmeter or Voltmeter -- allows you to select Amps or Volts as you wish to read them.

MFJ-4230MV has an excellent 75% efficiency and extra low ripple and noise, < 100 mV. Awhisper-quiet fan cools by convection and forced air cooling.

Normal air-flow around the power supply is continuous and a heat sensor increases the fan speed when the temperature rises above 70 degrees celsius.

DC output is five way binding posts on the back of the MFJ-4230MV so you can power your dedicated HF, VHF or UHF transceiver with ease.

All MFJ switching power supplies are protected by MFJ’s famous NOMatterWhat™ one year limited warranty.

MFJ will repair or replace (at our option) your switching power supply no matter what for one complete year

  3. VERY Quiet 5 Star Review

    Posted by on 19th Apr 2018

    I bought this power supply originally to store for when I get my HF rig put together. I decided to give it a try just to see what kind of noise it puts out during normal (to me) use of my dual band radio. I ran a local net here this past Tuesday (4/17/17) and this power supply never made a sound. My previous power supply would have made it much more difficult to hear incoming transmissions to the net. I think instead of saving this one for my HF rig, I'll just get a new one for it. Also, as always the good folks at MTC made my purchase seem effortless on my part and the power supply was at my door a day prior to when it said it would be! Thanks Richard and Christine for another great buying experience!

  7. Absolutely Silent 5 Star Review

    Posted by on 20th Apr 2015

    I bought this to power an Icom 7100. This power supply is ABSOLUTELY SILENT! It's only been in severe for a month, but I am very pleased with this purchase.


  8. very good supply 5 Star Review

    Posted by on 11th Dec 2014

    I purchased a second power supply.
    However the second one was very RF noisy.
    If this was my first one I would have been disappointed and not bothered to buy another. But because I know my first one was very RF quiet I new this one was noisy. a quick msg to MFJ, they immediately replaced it and the new one is as quiet or better than the first. these are good supplies. although I suspect every so often one is noisy.
