According to the embodiments of the present invention, a power supply remote control system for a variable information sign comprises: an electronic sign which displays traffic information; a DC power supply which, as an SMPS providing driving power in the form of DC to the electronic sign, detects an SMPS operation status and provides the result to a site monitoring PC, and performs power control according to a power remote control command received from the site monitoring PC; a site monitoring PC which relays the SMPS operation status received from the DC power supply to a VMS operation server, and if receiving a power remote control command from the VMS operation server, relays the received power remote control command to the DC power supply; and a VMS operation server which monitors the SMPS operation status of the DC power supply received from the site monitoring PC, and transmits the power remote control command including power on, power off and power reset according to the received SMPS operation status to the site monitoring PC. According to an embodiment of the present invention, it is possible to reduce maintenance manpower and cost by remotely controlling the power to the DC power supply for supplying the DC power to the VMS operating on the national highway and expressway.
