CUI’s Power Group has announced the addition of AC/DC power filters, designed to accompany its existing portfolio of low power embedded AC/DC power supplies. The EMC‑20 and EMC‑30 series offer 20 and 30dB of AC-line noise filtering at 150kHz to 1GHz, respectively.

Available in compact board mount, chassis mount, and DIN rail configurations, the models ensure surge compliance to the IEC/EN61000-4-5 standard and reduce conducted and radiated emissions to help designs comply with CISPR22/EN55022 Class B limits.

CUI’s AC/DC EMC filters further feature a wide input voltage range from 85-305VAC and accept up to 1.5A of nominal input current.

A 2,000VAC isolation voltage and wide operating temperature range from -40 to +85°C affords additional ruggedness in harsh environments. These AC/DC power filters ultimately provide engineers with a convenient modular solution for addressing EMC and surge challenges, while reducing the need for additional external components.

The EMC‑20 and EMC‑30 series are available immediately with prices starting at $6.95 per unit at 500 pieces through distribution.
