About Power Conditioners

Power conditioners are isolation transformers in enclosures assembled with a variety of associated electronic components to provide high levels of noise attenuation over a broad spectrum of frequencies. The main transformer design and selected components are chosen depending on the required level of noise attenuation. These are often combined with circuit protection, GFI's and/or any number of other electromechanical components.

Equipment manufacturers find it advantageous to add line (power) conditioning to their systems in order to protect against the instability of global power sources. Line conditioners protect against voltage spikes that can damage sensitive electronics.

QT&E power conditioners work to both protect systems from voltage spikes and increase throughput on yield by reducing electrical interference that can disrupt equipment functions and production processes.
