I'm having some difficulty figuring out when an AC line filter would be appropriate for an application. What exactly is being filtered, the amplitude? How does the filter protect against low-level transients as well as high-level transients... does it have an internal capacitor or battery to store a charge?
It sounds very similar to a UPS... how does it differ?
We have a customer who is convinced that the line power coming in is "dirty" and therefore we require an AC Line Filter ahead of our PLC and temperature controllers.
How do you determine if a customer has "dirty line power". Some sort of meter or device which can monitor a power line for an extended period of time?
Is it:
1) Based on the quality of the power coming in and the type of hardware being controlled? (i.e. if you have a microprocessor/PLC and your incoming power is off by "x" Volts, then you need a line filter?)
2) Based on the requirements of the equipment being powered? (i.e. the manual specifically recommends installing with the use of a line filter, and because of this you use one).
