1. An undersea device being used in an undersea cable system, the undersea device comprising:
one or more temporarily energizer being a temporarily energized portion during use;
one or more memories storing instructions;
one or more processors configured to execute the instructions to:
detect a specific functional operation is executed, the specific functional operation being set in advance as an operation using the temporarily energizer;
detect the specific functional operation is completed; and
an energization switch configured to supply power to at least one of the temporarily energizer when the one or more processors determine that the specific functional operation is executed and terminate supply of power to at least one of the temporarily energizer when the one or more processors determine that the specific functional operation is completed; and
a voltage setter between an input power supply line configured to receive a current from a power supply source being a land device, and an output power supply line configured to transmit the current to another device, the voltage setter configured to set a supply voltage, based on the current flowing between the input power supply line and the output power supply line,
wherein the voltage setter executes a suppression operation for suppressing reduction of the supply voltage due to the supply when the supply is executed.
