PURPOSE: A multi-channel blast power supply system is provided to enable successive blasting at a specific blasting region regardless of place or time. CONSTITUTION: A multi-channel blast power supply system comprises a variable transformation and rectification unit(120), a time interval input and display unit(130), a control unit(140), and a blast power output unit(150). The variable transformation and rectification unit transforms AC according to a winding ratio input by the operation of a rotary switch by a user and rectifies the transformed AC to output DC. The time interval input and display unit inputs a signal for setting the time intervals and starting output of blast power according to a button operated by the user and displays the set time interval and blast power output count. The control unit receives the signal from the time interval input and display unit to set a time interval, outputs a blast power output signal at the set time interval, and displays the time interval and blast power output count set in the time interval input and display unit. The blast power output unit outputs the DC provided from the variable transformation and rectification unit successively through multiple channels whenever a blast power output signal is provided from the control unit.
