Spike and Surge

[p2gee]

Got my BlueSpray up and running and it is fantastic.  Looking forward to any improvements down the road. I have a question......the power supply unit seems to be pretty robust, does it have spike/surge suppression built in to protect itself and the unit or something else required?

The controller does have a 1A fuse which will blow if there is a surge or short in the AC line, which should be good for normal use.  But nothing will stand up the power of a lightning unless you have a lightning arrestor.
