PS Comparison: Powerwerz SS-30DV vs. MFJ-4230MVP

Greetings all,
I am in the market for a compact power supply. The fact that Elecraft suggests/sells a third-party unit (SS-30DV) provides an automatic sense of comfort. However, always trying to complicate life I was also looking at the MFJ-4230MVP. Same dimensions, weight, power connections. I do like the variable voltage control on the MFJ. Not sure why I would need it, but seems useful. I doubt if anyone has BOTH units, but even your impressions of either of them would be very helpful. Thanks and 73, Bob KA2TQVKX3 #9842 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Bob,
I use an IOTA DLS-55 SMPS power supply ( https://www.iotaengineering.com/dls55.htm). It provides 55 amps, doesn’t produce RFI, is audibly quiet, and rugged. Mine is on 24/7/365. Iota also makes them in other output currents.

I've had an MFJ-4125 in the closet since I purchased my first K3. Given the experience with that product and it's flaws, I would not trust another MFJ power supply for any reason. It says everything that Elecraft resell the SS-30DV. They have obviously tested and stand behind that unit - that's all the recommendation I need. 73, ...

I use Astron SS-30M. This supply has both volt and current meters where
as the MFJ has one meter plus a switch. I see no need for an adjustable supply for the station. Set it at 14.0 volts and forget it. I do like to see both voltage and current indicated simultaneously. 73 Bob, K4TAX On 3/13/2019 12:08 PM, krug261--- via Elecraft wrote: > Greetings all, > I am in the market for a compact power supply.

I have the Powerwerx, relegated to the closet. One year after I got it
the fan became very loud to the point of being obnoxious. Easy enough to replace but unfortunately it isn't available anywhere. BTW, I didn't get this one from Elecraft. Now a nice quiet Astron RS-50M. 73, Dennis NJ6G On 3/13/2019 10:08, krug261--- via Elecraft wrote: > Greetings all, > I am in the market for a compact power supply.

Could the Powerwerx SS-30DV be the same supply as the Tekpower TP-30SWI minus the meter and a few dollars more? Anyone measure the efficiency of the Powerwerx, AC input vs. DC output power?

Hi Bob,
I have a Powerwerx supply, but my model is the SPS-30DM. Variable voltage, useful digital meter displaying voltage and current, and I've had no noise problems with it. It's another $50 above the SS-30DV's price, but I have no doubt noise will not be an issue with the model you listed. With best regards, Pete -- Peter N.

I've had the SPS-30DM for 7 or 8 years. I use it to power a K2/10 and
K2/100 plus all the external accessories. Quiet, absolutely solid as a brick. It replaced an old Astron RM-20A which would make a nice foot warmer and massager. Very happy the the SPS and Powerwerx in general. I buy nearly all my 12v power connectors from them.

I have both. Internally, the main circuit card is the same in both supplies. Hence, the similar packaging and form factor. There are places on the main board for different options, like the metering, voltage adjustment, etc. and that’s how they get the different models and brands. I’ve had no noise problems with either one. I have replaced a couple of fans on my Powerwerx supplies.

PS Comparison: Powerwerz SS-30DV vs. MFJ-4230MVP

In reply to this post by Elecraft mailing list
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.

> * The fan became very noisy. This was fixed by relaxing the securing bolts and placing thin spacers between the fan and the rear panel. Better solution: Get an ultra-quiet fan. I’ve replaced every fan in every power supply, computer, and piece of test equipment that I own. Totally inaudible, and cheap. They come in all sizes and various airflows and include compliant mounts.
