Filnor has a Flash version of our industrial electrical products listing with interactive display of knife switches, power resistors, grid resistors, load banks, and more.

Filnor will be launching a new website in 2007 complete with a more seamless quoting process, customer quote tracking, PDF downloadable and emailed quotes, eNews Signup, a new Tech Center with engineering drawings and online product catalogs, all in your private Filnor Customer Account!

Also new for 2007 will be our full color Filnor Knife Switch Product Catalog, and all of these products will be listed in the online quoting system too. Neutral Grounding Resistors brochure, manuals, drawings, and hopefully everything engineers require for their project quoting process will be made available as downloadable and printable literature.

Thank you for your patients.
Topic: Braking Resistors for Variable Frequency Drives

Application: Regeneration of Variable Frequency Drives

When a drive unit is attempting to rapidly brake a motor "Deceleration Braking Cycle" or when an "overhauling load" condition exists, the spinning motor acts as a generator. This freewheeling condition will force some voltage back into the drive unit (regeneration) which may cause an over voltage condition if the energy is not absorbed somewhere else.

Solution: Braking Resistors

Braking resistors are used to absorb energy that is being regenerated back into a drive unit by a freewheeling motor. The energy is released in the form of heat.

Visit our Braking Resistor page for more information, or contact Filnor.

Filnor can provide you with a complete list of standard braking resistors and electrical products or quote you per your requirements.
