Power conditioner

Power supplies are available to meet the power demands. AC power, although highly controlled, still produces significant fluctuations, transients and electrical noise. The AC power that is provided by the electric utility for the home or business is often fraught with noise, distortions, and other electronic pollution due to its proximity to industrial equipment, street lights, transformers, elevators, radio stations and home appliances. The advent of sensitive electronic devices in the consumer market has created a need to protect such devices from spurious and potentially damaging electrical spikes. Consumer electronics, such as computers and televisions and their associated peripherals, contain microcircuit electronics which are readily damaged by out-of-specification electrical power. A power conditioner is a circuit that connects between a power supply and the network connecting the process devices and controller to create the impedance needed to allow communication and power to co-exist on the same pair of wires. Power conditioning circuits have long been used to protect sensitive load equipment from transients caused by lightning strikes, noise and other power line disturbances. AC power conditioning is most often provided through a separate power conditioning device, commonly referred to as a surge and spike protector. AC power conditioners protect sensitive circuits from voltage spikes caused by lightning, electrostatic discharge and power surges caused by power grid interruptions and other potentially dangerous live transients. Power conditioning circuits used in two-wire networks are commonly broken down into two categories, passive power conditioners and active power conditioners. Multi-outlet power conditioners provide high purity electrical power to multiple electronic devices powered using a single wall outlet. Such devices often contain surge protection circuits for protecting consumer electronics, such as computers, televisions and other audio/visual equipment, from damage resulting from random power surges and voltage spikes. Power conditioners also typically contain filtering elements for reducing AC power line noise.
