(1) Output-Temperature: We need to reduce the output power depending on the operating temperature and the direction that the S.P.S. is allocated. Example: If the S.P.S. is vertically installed, output power can be 100% between 0 ~ 50℃, and between 50 ~60℃ the output power should be derated. At 60℃ we need to reduce the output power to [...]
