Comprehensive AC EMI Filter Product Range

DOREXS offers a comprehensive portfolio of AC EMI filters to meet different electrical, mechanical, and environmental requirements.

Single-Phase AC EMI Filters

Single-phase AC EMI filters are designed for standard AC power systems and applications with moderate electromagnetic compatibility requirements. They feature a rated voltage of up to 250VAC and a rated current range of 1A to 200A (custom options available), with a compact design suitable for space-constrained installations. They are commonly used in household appliances, office equipment, power adapters, and light industrial electronic equipment.

Medical AC EMI Filters

Low leakage current AC EMI filters designed for medical and healthcare equipment requiring strict EMC performance.

Multi-Stage AC EMI Filters

Multistage AC EMI filters provide enhanced attenuation performance over a wider frequency range, suitable for more stringent EMC standards. They effectively suppress common-mode and differential-mode noise, with an effective filtering frequency range of 10kHz to 30MHz, stable insertion loss, and low leakage current. They are widely used in industrial automation systems, medical equipment, precision power supplies, and communication equipment.

IEC Inlet AC EMI Filters

Integrated IEC inlet filters combining AC power entry and EMI suppression into one compact module.

Three-Phase AC EMI Filters

Three-phase AC electromagnetic interference filters are designed for high-power industrial applications operating on three-phase AC power grids. They have a rated current range from a few amperes to several hundred amperes (customizable up to 2000A), a robust and durable structure suitable for harsh industrial environments, and high reliability under continuous operation. They are suitable for motor drives, industrial inverters, renewable energy systems, and large machinery.

Custom AC EMI Filters

Customized AC EMI filter solutions designed according to electrical specifications, installation environment, EMC standards, and application requirements.
