Abstract
Provided is a power supply system in which two or more power supply units are optionally connected and used in any operation mode. A power supply systemincludes two or more power supply unitsto, the power supply unitstocooperating to supply DC power to a shared load, the power supply unitstoincluding a power supply main circuitthat converts AC power inputted from the outside into DC power; a control unitthat controls the power supply main circuit; a pair of synchronous terminals Z, Zrespectively connected to a pair of synchronous signal lines ZCL; a transmission unitthat outputs an error signal ER by establishing conduction between the pair of synchronous signal lines ZCL upon detection of an abnormality; and a reception unitthat detects a conductive state between the pair of synchronous signal lines ZCL and that receives the error signal ER, wherein the power supply main circuitstops outputting based on timing of receiving the error signal ER.
