In view of the above, the present invention provides a zero crossing detection means for an input voltage, a control means for controlling a load drive according to phase control, a power relay for driving a load by a load drive signal of the control means, and a contact between the power relay A phase controlled load driving device comprising a contact signal feedback means for sensing this operation and feeding it back to the control means, wherein the control means obtains the relay operation time, and the delay time obtained by subtracting the relay operation time from the zero crossing point. After obtaining and setting, the control method is configured to output the load driving ON signal by delaying the delay time set at the zero crossing point at the time of load driving. The cause of defect was eliminated.
