Ls Electric - FEP Series

The Ls Electric FEP series is a line of high-performance input EMC filters designed specifically for three-phase variable frequency drives. These filters help keep your electrical systems clean and compliant with strict electromagnetic compatibility standards. Whether you are working on industrial machinery, conveyor systems, or pump stations, the FEP series gives you the protection you need without adding unnecessary complexity to your panel.

Why Choose EMC Input Filters for Your Drives

Variable frequency drives generate electrical noise that can interfere with nearby control circuits, sensors, and communication lines. Without proper filtering, this noise can cause false trips, data errors, and equipment damage. The FEP series filters block high-frequency interference at the source, ensuring your drive operates smoothly while meeting Class B emission limits. This means fewer site visits, less troubleshooting, and a safer working environment for your entire system.

Key Features and Benefits for Installers

Installers love the FEP series because it is built for real-world conditions. The filters come in a compact, robust housing that fits easily into standard control cabinets. They are pre-tested for Class B compliance, so you do not need to run extra tests on-site. The straightforward wiring layout and clear terminal markings speed up installation time. Plus, the durable construction handles heat, vibration, and dust, making them ideal for demanding factory floors and outdoor enclosures.

Product Range Overview

The FEP series covers the most common drive power ratings to match your project needs. The FEP 3180 supports 90 kW inverters, the FEP 3250 handles 110 kW, and the FEP 3400 is rated for 180 kW. All three models are three-phase and designed for direct input connection to the drive. You can pick the exact filter that matches your motor power, avoiding over-specifying or under-specifying your setup. This modular approach keeps your inventory simple and your installations consistent.

Easy Installation and Reliable Performance

Getting started with the FEP series is straightforward. The filters connect directly to the line side of the frequency inverter, requiring no extra programming or configuration. Once wired, they work silently in the background to suppress electromagnetic interference. Their reliable design means long service life and minimal maintenance. For electricians and automation technicians, this translates to faster commissioning, fewer warranty claims, and happy end users.
