the impact of current large capacitor C1 affect the power supply itself; Second: Power-up the load eligible for a few seconds. In this process, due to the output of the relay J pull-in voltage of less than 12, from limiting the role of blood pressure combined R access to the circuit, with the power to C1, C3 is fully charged, the relay J pull short-circuit the contacts R, then, before the power supply into the normal working condition.
