Parallel Filters

Enerdoor three-phase parallel filters reduce electrical noise generated by devices such as variable frequency drives, SCRs, controllers, and other high-commutation electrical equipment.  They also protect against overvoltage spikes coming from the main power line which may damage devices inside an electrical cabinet.

Only one model is needed for any current range as it is not current dependent and works with any amperage. This filter is unique because it is compact and attenuates RF noise in lower frequencies than other EMI filters.

This line provides high attenuation in the frequency range of 10 KHz to 6 MHz offering a solution for applications with low to medium frequency concerns. When used in conjunction with other Enerdoor series, this combination ensures EMI-RFI protection for equipment in any environment. Many Enerdoor customers use this affordable solution to avoid equipment malfunctions and production downtime; which reduces technical service costs and increases profits.

This series offers a unique solution available with nominal voltage up to 750 Vac and any current level due to the parallel connection to the line. Offered in 3 phase and 3 phase plus neutral, this line carries CE and UL approvals and features panel and DIN rail mounting for fast and easy installation.

The FIN230SP.001.M Parallel Filter is the most general-purpose filter recommended by Enerdoor for OEM equipment. The FIN230SP family is affected starting at 70 kHz to 6 MHz and reduces interruptions due to quick spikes and dips. 

The FIN730.001.M Parallel Filter is a more specific design for regenerated systems and OEM equipment.  This filter is best utilized in the low frequency range of 10 kHz to 4 MHz.
