POWER SUPPLY SYSTEM FOR MOTOR-DRIVEN BED

摘要

PROBLEM TO BE SOLVED: To provide a power supply system for a power-saved motor-driven bed by minimizing power wasting. SOLUTION: This power supply system is constructed as two circuits having respective transformers, and an electric motor 80 is connected to the secondary circuit (electric motor side secondary circuit 63) of one of the circuits while a CPU90 is connected to the secondary circuit (controller side secondary circuit 73) of the other of the circuits. When the electric motor 80 is not actuated, the supply of power to the transformer (electric motor side transformer 62) intervening in the secondary circuit (electric motor side secondary circuit 63) to which the electric motor 80 is connected can be stopped whereby power can be saved.
