DESCRIPTION

The 3EXM4S is a high-performance slim power entry module featuring a three-element differential circuit EMI filter with extended attenuation suitable for bringing digital equipment and switching power supplies into compliance with FCC Part 15J Class B conducted emissions limits. This module includes a DPST on/off switch, four-position voltage selector (100V, 120V, 230V, 240V), and accepts either single 3AG fuses or dual metric fuses for flexible protection options. The compact design consumes minimal depth behind the panel, with flange mounting configuration and IEC 60320-1 C14 line inlet connector. Key performance characteristics include common-mode attenuation of 46 dB at 0.5 MHz and differential-mode attenuation of 62 dB at 0.5 MHz, providing robust EMI suppression across the frequency spectrum. The module is UL recognized, CSA certified, and VDE approved, making it ideal for industrial equipment, medical devices, and consumer electronics requiring stringent EMI compliance and compact panel integration.
