AC-DC Power Supplies DIN Rail TypeInstruction Manual1.9 Derating for low temperature start-up!Derating shown in Table 1.2 is required for low temperature startup.Table 1.2 Derating for low temperature start-upNo. Model temperature range Load factor1 KLEA120F, KLNA120F-40C to -20C 75%2 KLEA240F, KLNA240F3 TemperatureMeasurement Point!Ambient temperature indicates the temperature of the inlet of the air.2 Series/ParallelOperation2.1 Series Operation!You can use a power supply in series operation. The output currentin series operation should be lower than the rated current of apower supply with the lowest rated current among the power suppliesthat are serially connected. Please make sure that no currentexceeding the rated current fl ows into a power supply.Power +Supply -Power +Supply -LoadPower +Supply -Power +Supply -(a)(b)Load LoadAmbient temperaturemeasurement pointAirflowFig.3.1 Ambient temperature measurement point!Temperature of Forced airUse the temperature measurement point as shown in Fig 3.2.Please use at the temperature does not exceed the values inTable 3.1.Please also make sure that the ambient temperature does not exceed70C.Temperature Airflowmeasureing pointFig.2.1 Examples of connecting in series operation2.2 Parallel Operation!There is no current balance function.When operating in parallel, such as diode-OR, please use on theoutput voltage was adjusted enough to balance the current.Exceeds the rated output current, the output is shut down.!Redundancy operation is available by wiring as shown below.PowerSupply+-I1I3AirflowFig.3.2 Temperature measurement point (Forced air)Table 3.1 Specifi ed temperature of the measurement pointNo.Modeltemperature measurement point1KLEA120F, KLNA120F75C2KLEA240F, KLNA240F75CPowerSupply+-I2LoadFig.2.2 Example of connecting in redundancy operationEven a slight difference in output voltage can affect the balancebetween the values of I1 and I2.Please make sure that the value of l3 does not exceed the ratedcurrent of a power supply.l3 [ rated current valueKL-11
