The MFJ-4230MVP, Powerwerx SS-30DV, and Powerwerx SPS-30DM appear to be three of many variants of the same basic power supply. I have the Jetstream JTPS31MB which seems to be one of the same family. It has several different "punch-outs" to allow it to be produced in several different configurations. I expect they all come off the same production line.
I have been running this power power for over 6 years to power my TS-590S and a few ancillaries. It was worked well but there have been a few issues: * The fan became very noisy. This was fixed by relaxing the securing bolts and placing thin spacers between the fan and the rear panel. * There is also no provision for isolating the negative side of the supply from ground. My attempts to provide that isolation had unintended consequences so I removed the mod. My guess is they are all the same inside and the choice should be made based on preference for metering, voltage adjustment, and terminal configuration.
