PROBLEM TO BE SOLVED: To provide a power supply for an ultrahigh speed television camera, capable of suppressing the damage of an ISIS-CCD due to abnormality of power supply voltage. SOLUTION: The power supply supplies voltages, which are different from one another, to the ISIS-CCD mounted on a CCD board 10 and a power supply control circuit FPGA mounted on a control board 30 from DC/DC converters 201 to 207 of 7 circuits mounted on a power supply board 20. The power supply is provided with a plurality of monitoring parts 401 to 408 for monitoring voltages supplied from the plurality of DC/DC converters 201 to 207. When a DC/DC converter in which voltage becomes abnormal is detected among the plurality of DC/DC converters 201 to 207, all of the plurality of DC/DC converters 201 to 207 are simultaneously turned off to suppress the damage of the ISIS-CCD.
