In many homes and industries sometimes a fan does not turn ON immediately, here, a fan start delay timer is a circuit that delays the fan start. When we apply power, the fan remains OFF for approximately 10 seconds and then turns ON automatically. Also, we can easily adjust the delay time if required. This […]
