Post Subject: The PurePower and … a compressor.Posted by Romy the Cat on: 11/20/2013

It was an interesting event today. I have a big air compressor home that got broken, so I borrowed a portable electric compressor from my neighbor. I plug it in outside the house and blew up the irrigation system, preparing it for winter. Then I brought the compressor in Opera Room as Amy wanted me to put some trim in the wall. The compressor did not start. I figured that I broke up the neighbor compressor. The thing did juts 2-3 puffs and choked. Interesting that as it tried to start it sunk the voltage in the whole house, the room lights went very dim and the PP2000 that powers Opera Room equipment switched to battery operation.

I was trying it a few times and then my 20A fuse went off. OK, I figured, the motor or compressor is cooked. I brought the compressor to the neighbor telling him that I broke it and now I owe him a compressor. It was my surprise when the neighbor informed me that the compressor works just fine.
Well, to make the long story short and after many experiments I concluded that the compressor sucks over 35 and not willing to start only if it plugged into the same circuitry where my PP2000 plugged. Of cause I do not plug the compressor into PP2000 but rather use the same wall outlet, of the wall outlets of the same AC phase. As soon I unplugged PP2000 from the wall, of use another AC side the compressor starts and works just wonderfully.

This is an interesting observation. It might be that the compressor is defective and has some strange start up electronics that somehow interact with AC noise that PP2000 injects back to the wall.
