Product Overview
The CUI VFM-30 is a DC power line filter designed to ensure surge compliance to IEC/EN61000-4-5 standards and reduce emissions to meet CISPR22 / EN 55022 Class B. It accepts up to 1.5 A (rms) of nominal input current across a wide input voltage range (10-36 Vdc) and operating temperature range (-40 to +85 C). Available in board-mount, chassis-mount, or DIN-Rail mounting options, it is designed for use with PYBE30-Q24 DC-DC converters, providing enhanced protection and compliance for power systems.
