Jrifedptry 600W High-Power Amplifiers Speaker Amplifier Board 12V to 45V 48V 50V for Tpa3255 Tas5630 Board

Output voltage: This machine is a shallow closed-loop circuit. The output voltage change with the input voltage. It is about 44.5V at 12V input and about 50V at 13.5V input. The output voltage is an approximate value and have a deviation of 1-5V. The power supply of the power amplifier is a wide voltage. , it doesn't have to be an exact value. If you mind about this, please don't ! Input voltage: 10-15V, if it is lower than 9.6V, it enter the protective shutdown state; The power supply requires tens of amps, so please use thick wires! Thick line! Thick line! Avoid loss leading to insufficient power supply. REM is the control terminal, where a switch or the car's ACC terminal can be connected to control the power on and off.
