Technical characteristics There are few external components. The external power supply has a wide voltage range and its value is 4 to 11V. The SAA3004P is a 20-pin dual in-line plastic package. The SAA3004T is a 20-pin small plastic package. The matching models are TDA3048, SAA3009 and SAA3049. High voltage slip ring is also called high voltage slip ring,high voltage resistance slip ring, high voltage collector ring, high voltage convergence ring and so on. High voltage usually refers to the alternating curred by the slip ring, and the voltage to the ground exceeds the conventional 380V AC/DC path.
