Silent transfer switch?
So the oft recommended Progress Dynamics PD52DCS is going through production changes and there's no update on when they'll be available for purchase. I'm looking for alternatives to the original one under my bed. Has anyone purchased one recently...

Probably not what you want to do, but I completely eliminated the ATS.  Now we have total silence.  See post linked below and following posts:

Thanks Michelle,
I haven't had any dealings with that one , yet, and have never heard anything humming.

Hum is eliminated when shore-power contactor relay coil is powered with DC instead of AC. Hum is a natural byproduct of AC relay coils, although most AC coils are pretty quiet.

Chuck after doing a bit of research on the manual switches, I'm pretty blown away by how much they cost.
Yes, Blue Sea Systems products are pricey.  People who buy them obviously believe they...

Chuck, i think the DC powered coil transfer switches are more money.

Amazon.com: Progressive Dynamics PD52V 5200 Series Automatic Transfer Switch...

The Progressive Dynamics PD52DCS with 12v coils is sold out almost everywhere.  It was more $.

Yes, but probably less than a $300 manual switch?  I haven't priced them, so I don't know (and don't really care).

Can anyone confirm their DC powered ATS is truly silent? I keep reading that it "reduces hum" in the descriptions but I want zero hum. Need to be able to hear a mouse fart outside.

Also, if anyone has installed one I'd love to hear where you...

Elliott,
I believe the Progressive DC unit create their own DC power inside the box; so you don't need supply it with power.

Just a couple months ago I helped another Foretraveler replace his "AC" progressive transfer switch.  It buzzed when...

I have a transfer switch that is silent.  When I plug in it does not appear to energize a relay - i.e. no click.
John,

That is an interesting ATS.  From the photo it doesn't appear to have any...

All I see in the photo is a terminal strip with three feeds coming in and going out the back of the box to "somewhere"?  Not sure what the blue leads are for as they don't appear to be connected to anything.

More photos or info is...

There are two relays under the terminal strips.
The blue wires appear to be for a 4th switched wire (AUX N2) - typically not used.
There appears to be a bridge rectifier to create a (poor quality) DC from the AC.  There's another quad thing in...

What are the wires connected to that go out the back of the J-box? I see what appears to be a couple of solid state (crydom maybe?) relays under the terminal strip. The actual transfer switch must be behind the J-Box?

Thanks..

I decided to go with the guaranteed silent option and bought a manual transfer switch. I was able to get the Blue Sea 9093 new off eBay for $235 so I saved a bit. Once I get my DC2DC charger installed the switch will spend most of it's life set...
