EMI Filters for Industrial Electrical Measuring Equipment

EMI power line filters solve EMC challenges for both common and normal mode RF noise.

Electromagnetic Interference (EMI) is an electromagnetic emission that can destroy electrical measurement equipment. APITech power line EMI filters are ideal for filtering the AC or DC power entering these instruments, preventing EMI from causing damage. They are designed to attenuate all radio frequency emissions or energy above the applicable electromagnetic compatibility (EMC) specification.

 

 

APITech’s power line EMI filters provide excellent attenuation of high voltage impulses. Available with fast-on, bolt-in terminals, or wire leads. Single-stage and dual-stage products, and high performance in both metal and plastic cases. They are ideally suited for products that must conform to FCC part 15 regulations.

 

DC - High Current EMI Filter
12-PMF/PMB Series

 

This series of EMI filters feature space-saving, compact construction. They are ideal for applications with higher current designs, up to 260A rated current, and the structure of these EMI filters provides effective shielding for noise generated externally and internally.

 

 

AC - Appliance EMI Filter
11-MPC Series

 

This series of EMI filters is an economical option for a PCB-mounted option. The availability of up to 16A rated current allows it to run cooler than lower amp products. Its metal case option is better for grounding and shielding than plastic.

 

 

 

AC - Dual Stage, High Performance EMI Filter
12-MMF/MMB Series

 

APITech offers a wide variety of dual-stage filters with rated current products up to 50A. The two stages with this product provide excellent filtering characteristics and are epoxy molded for reliability.
