Got a new Nema 4, 16" X 14" X 6" control box for free from a friend that works for an institutional greenhouse contractor. I wanted just a box, but all he had was a leftover shade control box fully wired. The whole thing is brand new and the box is nice. I am wondering what use I can get out of the guts.
It has a fan and vents installed in it, so that will work for my SSR's.
It has 3 din mount 24 volt relays that are for 1/6 hp 120 v motors or 1/3 hp @ 240 V - possibly pump control instead of SSR's ?
There is a 1 amp supplemental circuit breaker
There is also a Telemechanique variable speed drive for an asynchronous motor. Here are a couple of links...
It sits on a heatsink with its own separate fan and is programmable for speed settings. I don't think its any good for heating elements since it does not have the amp rating and its for inductive and not resistive loads.
Its new, so I guess I could sell it on ebay. there is also a circuit board that controls the operation of the shade to open, close, off and auto which operates at 24 volt.
I have an electric herms system that i just finished, but I am always looking for better ways to do things especially when they are free.
thanks for any ideas.
