Default New MFJ "MightyLite" Switching Power Supplies


I just got this press release about the new line of small form factor variable voltage switching power supplies from MFJ. The 30 amp supply is only 5 inches wide!



Here is the press release:

MFJ MightyLiteTM 30A Metered Switching Power Supply
MFJ-4230MV, $89.95

This is the world’s most compact switching power supply that also has a meter and adjustable voltage control. Just 5Wx21/2H x6D inches, 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. A whisper-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.

MightyLiteTM 28 Amp Switching Power Supply, (no meter), $84.95
MFJ-4128 can power your HF, VHF, or UHF mobile or base transceiver with an output of 28 Amps maximum and 25 Amps continuously at 13.8 VDC. This basic power supply has all of the output connectors you will ever need -- has five way binding posts for high current rigs and quick connectors for low current accessories. It also has a low 7 amperage cigarette lighter plug, perfect for powering small accessories. It is super lightweight (only 4 lbs.) and super-compact 7Wx21/4Hx71/2D inches, so it can still be carried on your business and vacation trips to far away and exotic locations. Features over-voltage and over-current protection systems and has a quiet internal cooling fan with “fan on” LED. Take it worldwide! MFJ-4128 features a selectable AC input voltage from 85 to 135 VAC or from 170-260 VAC -- take it around the world!

MFJ-4230MV and MFJ-4128 areprotected by MFJ’s famous NoMatterWhatTM one year limited warranty. MFJ will repair or replace (at our option) your MFJ antenna no matter what for one complete year.

When I was a child
I caught a fleeting glimpse
Out of the corner of my eye.
I turned to look but it was gone
I cannot put my finger on it now
The child is grown,
The dream is gone.
but I have become comfortably numb.

Could be the same manufacture building different brands, or supplying the cases that are used.
Just like many things.
I used to work for a Company called Hull`s Inc, building Aluminum Boats.
All built by the same people, but depending on the model, and the label put on in the paint shop, It was a Valco Boat, A WestCoaster Boat, Or a BayRunner Boat.

What do you mean "Better off with a regulated."? Both switching and linear type supplies are regulated.

I do love my DLS-55's (I have two of them). But you have to admit, adjustable voltage and a lighted meter would be nice to have. The IOTA's are soooo utilitarian.
