DC Filters
-
This DC filter provides substantial noise reduction 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. DC filter provides noise suppression for both power lines – 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.
