Power amplifiers are suitable for all of our single color & RGB controllers to expand power output,
it supports PWM control and can connect one to three times more circuits by adding one more power amplifier,
and unlimited power amplifiers can be connected together theoretically.
The constant voltage power amplifier and constant current power amplifiers can be connected together,
which is convenient for controlling circuits with different voltage and power.
Signal input and output of power amplifiers have security protection function with photoelectricity isolation of 5KV.
