[sdiy] DIY Sequenced Power?

[Dave Magnuson]

Hi Joel,

 

I’m a mechanical (HVAC) engineer for my day job.   Look for DIN rail time delay relays.  We use them all the time in high voltage / amperage situations (triggering a fan to start 1 minute after the hot water valve opens, etc)

Here’s Eaton brand.   There are many others, and there are many options

 

Maybe these will work?

 

Dave

Thanks for these suggestions... none look like they are designed for the kind of power draw that I would put through them, I was thinking more of a DIY project with relays or something, maybe IR controlled... interested in suggestions on component parts that could pass a lot of power without melting or shorting out.

A more expensive approach (if you need more channels) is the "smart home" WiFi market, e.g.:

But these would probably add up very quickly to be more than a decent sequencer.

Here's one from a local hardware store:

They are no doubt plentiful online.

 

Meets the low cost part of the requirement (if you don't mind manually pressing buttons in order), but this type only has 4 channels.

Maybe a few of those remote control (RF) outlets? You can use a few outlets off the same remote, just set the right channel for each.

 

Check output rating vs load.

Hi SDIY, I have a pile of power conditioners in my studio and have to walk around crawl under various things to power it all on and to power it all off. The idea of putting them all on one sequential power box on one outlet seems pretty dangerous, not to mention $250-650 for a power sequencer that the 6 conditioners could hang off...

Any ideas for sequentially turning on 6 separate power supplies in a room, each on a separate outlet? What parts would you choose to build such a thing?
