#29 Electricity Massage

Good morning!

Hope everyone sprung forward and is as tired as I am. My main PC had the Microsoft Patch and leaped without incident. We'll see how many calls I get today to keep the PCs in step.

Electric utilities do a fine job of providing power to us 24/7. They aren't real big on quality control. The variation of power provided can be harmful to your technology items that feed on pure electricity. Optimally, in the US, you want 120 volts of alternating 3 phase electrons heading your way. Note that most gadgets take that 120 volts and transforms them into direct (DC )current. I've seen as low as 103 volts and as high as 132 volts coming out of wall sockets. The transformers don't like that range of power and can do some interesting (read expensive) tricks when not fed their required 120volts.

We keep all of our valued electronics on UPS (uninterruptible power supply ). These black boxes have batteries that let them provide pure 120volt power no matter what is coming in to them. They also can provide power for a limited time should your faithful utility become unfaithful (read blackout). The price on UPS is pretty low ($49-$99) for most electronics. they need to be sized to match what they are protecting. Oh, and did you know that PCSS sells these gems? Go Figure. Have a great week.
