MFJ-4275MV 75 Amps Switching Power Supply Review

Does anyone know where the internal voltage adjustment is on the MFJ-4275MW power supply? The voltage on mine is a bit low at 13.2 volts at the detent setting. When I put about 45 amp load the voltage drops to 12.9 to 13.volts.
 
It's not that unusual for a little voltage drop on these supplies when under load. It's not ideal, but it doesn't hurt anything.
 
An update on this power supply: It's developed a strange problem where the output voltage is completely random and is dropping voltage pretty too much under load. It's become particularly annoying: one day the voltage output will be 15 volts; the next day it will be 12v without adjusting anything and without a change in load. I'm going to start moving stuff over the MegaWatt supplies and use this supply as a general garage unit.
 
my jetstreame is doing similar . when i turn it on it reads differently than last time i used it. but when under load it doesnt move . those mega supplies i know nothing about other than pics on web. but got lotta quedtions
1/wheres power cord connection at for 110v
2/wheres power poles for hooking up devices to it

There is good information on this site about the Megawatts and you can do a Google search as well or start a thread.

    Good day, I have an Icom IC910H radio. I want to program a memory with split frequency tone on TX only and NO tone on RX,. Is this possible to do from the face of the radio? I don't have the interface to connect to a computer.
  • @ crappykraco:
    @Deon very unlikely to get a response here. You are better off starting a thread on the topic.
