源装置。[Scope of Claim for Utility Model Registration] A main power supply circuit that supplies predetermined voltages to control units such as a numerical control unit and a relay control unit, respectively, and a first relay that cuts off and on the supply of commercial power to the main power supply circuit. , an auxiliary power supply circuit that supplies voltage to the coil of the first relay, and a voltage monitoring circuit that monitors the output voltage from the main power supply circuit and outputs a permission signal to the control unit if the voltage value is a normal value. and excitation means, which is located within the control unit and excites the second relay only when the permission signal is input and the operation within the control unit is normal, and is supplied with voltage from the auxiliary power source and is powered on. A self-holding circuit that energizes the first relay when the push button switch is pressed and allows the first relay to hold itself only when the second relay is energized. Power supply equipment for numerically controlled machine tools.
