Product description
Power amplifier board power and power supply description:
The power supply of this power amplifier board requires 12-24V3A DC regulated switching power supply (please do not use battery and charger, transformer and AC switching power supply for testing)
12V3A (above) power supply. The maximum output power is 20W 8 ohms. 20W bass + 5W treble can be connected (full volume may be distorted)
24V3A power supply. The maximum output power can reach 30W8 ohms. 30W bass + 10W treble can be connected (4 ohm speakers may be protected) (full volume may also be protected)
After the test is completed, the battery can be connected to the power supply after receiving the goods (the 24V battery is not allowed, because the battery may exceed 25V after being fully charged, and the capacitor on the board is 25V, there is a risk of explosion!)
24V batteries of large trucks are not allowed. Because the charging voltage reaches 28-32V when the large truck is on fire, it will burn!
