New energy regulation standards force 24VAC Transformer change

zoning supplyComment

As of RIGHT NOW, ZoningSupply transformers will no longer have LED indicators or "resettable" fuses built in.  This is due to some new governmental regulations that apply to all power supplies less than 250W.  They must have lower power usage (wattage) when not in use.

You can thank the Department of Energy (DOE) for this rule they implemented back in 2012 that is just now taking effect.  A few milliamps to power an LED seems like a lot of effort for not much gain... however, anything that reduces energy usage is ok with us.
