Switching landscape LED loaded transformers with HAI UPB

[CanuckAutomator]

This is my first post so go easy on me.  I’ve inherited an HAI Lumina system in my home and am in the middle of expanding the automation to landscape lighting.  I’m looking at ways to control about 5 zones of LED landscape lighting.  For flexibility I’m considering each zone to be powered by single circuit transformer.  My question is, can the zones be switched by a 15A Relay UPB (40A00-1) or a 600W UPB Non Dimming Switch (35A00-3) if I am using 300 watt transformer with around 200 watts of connected load?  I like the idea of being able to manually turn the zones on and off with a switch if desired plus the usual codes for automated control.  Feedback is appreciated.

The relay switch for sure. The dimmer IF it supports magnetic loads AND the transformer is spec'ed to be dimmable, some are, some aren't.
 
Then there are things called LED drivers which are basically power supplies designed for powering LEDs and these come in a variety of types, some of which are dimmable using a 0-10 volt DC signal.

Here I converted some 10-12 12VAC LV lighting zones to LEDs.  Just this past weekend changed 16 deck lamps from single bayonet LED lamps to 4 LED per lamp bayonet mounts.  They are spaced evenly on the railings and I have installed them on the two sets of stairs to the deck.  They are brighter but its indirect lighting facing down small footprint "sconce like" housings.  Single LEDs were some 1/10 of one watt (10Mw) and these are a bit under 1 watt- with total being under 16 watts.
 
I went to DIN mounted Meanwell 3 120 & 1 75 watt 12VDC power supplies using the 15A Relay UPB (40A00-1).   I divided up all of the zones per DIN DC PS.  They are not individually fused though; but the PS have protection circuits built in.  I didn't see much of a difference between these and the propietary lower wattage 12VDC for LED power supplies.  These now have been "online" for over a year.  The setup has a more industrial look to it rather than a residential look.  I did get "bit" by that whole DIN rail thing methodology.  I am beginning to utilize these DIN rails and mounting things for other stuff lately.  IE: like mini PC mounting stuff.
 
I did have issues with switching on and off the larger 1000 watt toroidal transformers.  I even ran separate breakers for each one and connected each one to separate automated switch.  Whatever switch I tried to use it would throw the breaker.  Funny though the last one that worked and didn't throw the breaker was X10.  Insteon, Z-Wave and UPB still would throw the breakers.
 
Playing with cantex boxes lately; I will most likely just put a DIN rail inside of a cantex box and put a clear plastic window on it such that I can see the LED status lights on the Meanwell power supplies.
 
I do not plan on dimming any of the 12VDC powered LED lamps at this time.
 
I am looking though to move the power supply to 12VDC storage batteries and utilize solar panels to charge the batteries.
 
I would like to continue to control them with the HAI OPII panel but do some 12VDC per zone RF switching if I can.
 
I am playing now though with multicolor remote control LED lamps; just one for now.  It does work fine outside.  These are programmable and dimmable.  I am amazed so far.
 
I can change the color of the single LED lamp and dim it with the remote control.
