SELENIUM SURGE SUPPRESSORS
steadystate power dissipation up to 40 times that of an MOV. For a 130V suppressor, the selenium product allows steady-state dissipation of 2.5W to 80W, compared with an MOV that allows only 0.1W to 2.5W. Typical applications for selenium suppressors include: ? On the DC side of a rectified generator output. ? Across the SCRs on large controllers. ? Across DC motors. ? On transformers (for line-to-line suppression). ? Power conditioning (i.e. from power strips to service entrance). For some devices... (read more)

What is an Electrical Transient?
is internally generated. Copiers and laser printers, for example, are notorious transient generators - as are heating and air conditioning systems. Any time an inductive load, whether it is a vacuum cleaner or a heavy duty variable speed drive, is either powered on or off - it generates a low magnitude surge
