Instruction Manual AC-DC Power Supplies Enclosed type 1 Terminal Block 2 Function lUAW125S 2.1 Input voltage range The range is from AC85V to AC132V/AC170V to AC264V which is automatically selected internally. But after the input voltage is applied, avoid changing AC100V/AC200V. AC input voltage must have a range from AC85V to AC132V/AC170V AC(N) to AC264V for normal operation. -
