Avoid using Hi-Pottester with timer because it may generate voltage a few timeshigher than the applied voltage at ON/OFF of a timer.3.8 PMBus interface?-I (CHS300,CHS400,CHS500)!This option is equipped with a digital PMBus interface.Please contact us about for details.4 Series and Parallel Operation4.1 Series operation!Series operation is available by connecting the outputs of two ormore power supplies, as shown below. Output current in seriesconnection should be lower than the lowest rated current in eachunit.(a)(b)Power +Power +Supply -Supply -Power +Supply -Load4.2 Parallel operationPower +Supply -Fig.4.1 Examples of series operation?-P (CHS400,CHS500)!This option is for parallel operation.!Sensing and adjustment of the output voltage are not possible atthe time of the use with this option.!As variance of output current drew from each power supply ismaximum 10%, the total output current must not exceed the valuedetermined by the following equation.(Output current in parallel operation)=(the rated current per unit) x (number of unit) x0.9When the number of units in parallel operation increases, inputcurrent increase at the same time. Adequate wiring design for inputcircuitry is required, such as circuit pattern, wiring and currentcapacity for equipment.!Total number of units should be no more than 3 pieces.!Thick wire should be used for wiring between the power supplyand load, and line drop should be less than 0.3V.!Connect each input pin for the lowest possible impedance.!When the number of the units in parallel operation increases,inputcurrent increases. Adequate wiring design for input circuitrysuch as circuit pattern, wiring and current for equipment is required.LoadLoadCHS-43
