Product Overview
The CUI EMC-20 series AC Power Line Filter is designed to reduce AC-line noise and emissions, helping equipment comply with stringent EMC standards such as CISPR22 / EN 55022 Class B. It ensures surge compliance to IEC/EN61000-4-5 standards and accepts a wide input voltage range (85~305 Vac) with a nominal input current of up to 1.5 A (rms). This filter is ideal for protecting AC-DC modules and other sensitive electronics from power line disturbances, operating effectively across a wide temperature range (-40 to +85 C). Available in board-mount, chassis-mount, or DIN-Rail mounting options, it offers flexibility for various integration needs.
