Q: what is the use of relay?

Задавает rajan11021987 на 2018-03-20 06:41:27

child_john I have used one of these units with great success! if the power is lost ie supply failure, it turns down volume before resuming so works fine the relay function is and open collector which means you can connect to a relay driver of a stand by power supply this unit needs to be run from standby always on supply , it can then turn on and off the main heavy duty power supply to your amplifier
