I recommend you to make a Simple speaker delay circuit. Imagine you finished a normally OCL power amplifier. Every time you turn on within the first 3 seconds. You may…
This circuit prevents surges. From the opening is switched off or power failure. The damage to electrical appliances.
Power failure, voltage drop, power surge, but do not worry when has this circuit.
This is Simple monitor turn on delay circuit, by use contact of relay acts as a switch. When entering an AC main to this circuit. The circuit will delay while Reduce the surge current protection with fuse.
