PM 0005

50W Audio Power Amplifier
PM 0005 allows continuous output of 50W in 4ohm/8ohm loads. With its compact size, it has a dual channel stereo output of 50W, which can be used to drive passive speakers, artificial mouths, vibration tables, and other devices.
PM 0005 has overcurrent, overvoltage, overheating, and short circuit protection. When the device triggers protection, the alarm indicator light will light up and the internal signal output will be cut off to ensure that the audio or other load devices will not be damaged.
