BitShield’s power line EMI filters are a flagship product family developed for protected facilities, sensitive electronics, and demanding electrical environments.
Designed for practical integration and strong attenuation performance, these filters support resilient power system operation where electromagnetic interference must be controlled with confidence.
Our EMI filter family is one of the products that helped establish BitShield in the market, and it remains an important part of our broader engineering and technology platform.
AF4x160AR
High Attenuation Performance: Delivers 60dB attenuation from 100 kHz to 6 GHz, operating at AC 110–400V with 5W power dissipation. Ideal for server rooms with electromagnetic shielding.
Optimized Design: Supports simple connections using 1.8–16 mm2 wires and single or twin 80A terminals.
AF4x640AR
Exceptional Load Capacity: Designed for 4x320A filtering with only 11W power dissipation, offering outstanding stability for critical infrastructure.
Robust Configuration: Features MAA2150 terminals to accommodate cables up to 150 mm2.
AF4x490AR
High Power Capability: Supports 4x245A per line with 60dB attenuation from 100 kHz to 6 GHz and 8W power dissipation. Achieves 100dB attenuation up to 40 GHz.
Streamlined Installation: Equipped with MAA2095 terminals, allowing easy use of cables up to 95 mm2.
AF4x160ALL
Wide Application Versatility: Functions as both a two-phase and four line three-phase mains filter, meeting EMC standard requirements for electrical and electronic equipment. Handles up to 160A per line at AC 110–400V in industrial environments.
Compact Design: Features a small footprint with extremely low power dissipation of 2W, compliant with electrical safety standards at minimal leakage current.
Durable & Reliable: Operates eectively across a temperature range of -25°C to +85°C.
These EMI filters enhance power system eliability, reduce electromagnetic nterference, and ensure full compliance with industry standards.
