I can’t determine the difference between the pm3 & pm4 versions.

LOL me either.

I believe the PM3 is the old version, PM4 is the new version. I think someone said the 3 is 3 stage charger and 4 is 4 stage charger. There should be a switch on the side to switch between battery charger mode and fixed output. Checkout the reviews on Amazon, several hams are using these. eHam has a good review too.

So it was fast shipping but no email notice of shipping, it just showed up. Good thing it wasnt raining.
Definitely will have to be a little creative with these small terminals.
I have a little 2 pill ill try it out with later today or tomorrow. Been busy putting a new roof on the house this week. Still have to finish screwing it down. New siding is next.

Did you order them directly from MegaWatt? I have three of them ordered at different times. I received an email each time thanking me for the order. The next day I would receive a second email showing the USPS Tracking Number.

This seems like a cheap deal for a 60 amp $43 canadian on amazon but probably load for fans as I notice of this type ps, I have to ebay 30 amp units and fans are loud.

Fan on the megawatt is very quiet and the unit seems well filtered. I like this model better than the s-1200 I had.
This was the best I could do after filtering thru my junk pile(s)

What wire gauge and what size lug are you using on the black and yellow wire?

Tokin - where did you get those connectors for the bigger wire?

Those connectors actually came with the unit.

As far as the gauge wire I havent a clue and the lugs came with the unit. I know they were a little too big for my crimper

Those same red connectors came with my S-700-12 MegaWatt power supply.

I had to place the crimper one handle down on the workbench and push hard on the other handle but I got them to crimp.

Was going to say my 30/33 didn't include them. I'm stuck running 10ga for about 2' to my Palomar 4 pill (as a base setup). But think I should be good for now.

I also have two S-400-12 MegaWatt power supplies.

I zapped one of those power supplies with a 4-pill TNT amp. Got carried away talking SSB skip put TNT on high setting & turned up power slightly on AT-6666. I new better. That was not enough power supply for the 4-pill.

The radio and the 4-pill were running off two different S-400-12 power supplies. Radio and Amp are OK....power supply, nope.

probably going to get a PowerMax 100 supply.

How are you to connect 8g wire to these megawatt s-700-12
