XH-M189 2x50W High-end Digital Amplifier Board DC24V TPA3116D2 Dual-channel Stereo E-892 Chip: TPA3116D2 Operating Voltage Range: DC 12V-24V Output Power: max 50W dual channel Working Frequency: 20Hz-20KHz Audio Type: dual channel stereo Signal to Noise Ratio-100db Output Power (W)- 2x50W

Module feature and performance: 5A high-power and high efficiency reduction voltage and low ripple High quality and good performance With power light and voltage display with self-correcting. Adopting advanced voltage microprocessor, and the voltmeter error ±0.1V, measuring range is 0~40V (Note: Please make sure input voltage more than 3.5V to make the voltmeter normal working) Touch the button to change input or output voltage, LED indicator light display is measuring voltage, and can autosave which one voltage, keep pressing the key can turn off the voltmeter Input voltage 4.0～38V (the input voltage must be higher 1.5V than output voltage) Adjustable output voltage range: 1.25V～36V (the input voltage must be higher 1.5V than output voltage) Output power can reach 75W. Output current can reach 5A, suggested use it less than 4.5A (note: Please add a cooling fin into power chip, if you use it with high-power)
