Power line filters for shield class facility
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.
