DC EMI Filter 50V 9A DCNG5009

This filter qualifies for UL 508A panels by being low voltage, low energy device

This DC EMI filter provides substantial reduction of electromagnetic interference on DC power lines of up to 50V 9A.  Filter provides noise suppression in both directions protecting your DC lines from noise generating by a particular piece of equipment, or protecting your sensitive equipment from noise coming from DC power supply or other loads.  Other applications include reducing EMI in LED lighting and alike.


DC filter DCNG5009 provides EMI suppression for both polarities - positive and negative, plus common-mode noise vs. ground.  Filter uses plug-in terminal block for connections and mounting flanges for easy installation.  Its rugged construction makes it easy to fit in many industrial tools.
