Some UPSes such as the Best FerrUPS series and other voltage regulators and line conditioners that use a ferro-resonant transformer where there's an L-C tuned circuit as part of the power transformer. Other motor loads may care to some extent. Analog electric clocks will run slow or fast, no big deal. Lower freqencies are harder on marginally designed transformers which may not have enough core material. -- Jay Hennigan - CCIE #7880 - Network Administration - [email protected] WestNet: Connecting you to the planet. 805 884-6323 WB6RDV NetLojix Communications, Inc. - http://www.netlojix.com/
