Product Classification

Precision EMI/EMC Control Systems: Military-Certified Filters, HEMP Shielding & Industrial-Grade Solutions for Critical Facilities

Power line filters for shield class facility

These specialized EMI/RFI filters are engineered to maintain electromagnetic isolation in high-precision shielded environments such as anechoic chambers (10KHz-40GHz), TEMPEST-grade shielded rooms, and communication cabinets. Key products include anechoic chamber power filters with >100dB insertion loss for radar testing, shielded room feedthrough capacitors compliant with GJB6190-2008 for 500A current loads, and ground wire signal filters that eliminate 30MHz-1GHz interference in control systems. Designed to meet MIL-STD-461G and IEC 61000-4-5 standards, they ensure signal integrity in defense labs and industrial EMC testing facilities.

Power line filters for industrial system

Engineered for harsh operational environments, these robust filters effectively mitigate harmonics across a wide range of machinery—from 250V single-phase food processors to 480V three-phase CNC systems. The product lineup includes IEC connector filters designed for robotics, as well as military inverters certified to both MIL-STD-1275 for hybrid energy systems. Typical applications include high-efficiency (up to 98%) solar and wind converters, naval power units, and industrial automation equipment compliant with EN 55011.

HEMP power line filters

Designed as critical infrastructure guardians against electromagnetic warfare, HEMP filters are capable of withstanding transient electromagnetic fields up to 50 kV/m, in full compliance with MIL-STD-188-125. These rugged filters ensure uninterrupted system operation through zero-downtime failover during high-energy EMP events. Validated by China’s State Key EMC Laboratory for shielding effectiveness up to 40 GHz, they are trusted to protect high-stakes environments such as nuclear power plant control systems and satellite ground stations. Their dual certification to both MIL-STD and GJB standards guarantees reliability for military EMP protection and the hardening of essential civilian infrastructure.

Shielding materials and equipments

Complete electromagnetic sealing systems featuring waveguide ventilation windows (40dB@18GHz hexagonal design), aerospace-grade fingerstock gaskets, and 316L stainless steel knitted mesh (1,000-hour salt fog resistance).14KHz-40GHz shielding rooms, this range serves 5G base stations, automotive test labs, and electronic warfare enclosures with end-to-end shielding integrity.
