DC-DC Converters PCB Mount TypeInstruction Manual!If the distance between the output and the load is long and thereforenoise is created on the load side, connect a capacitor externallyto the load as shown below.4 Input Voltage/Current RangeInput+Vin +Vout-Vin -VoutFig2.4 Connecting ExampleCoLoad!If you use a non-regulated power source for input, please checkand make sure that its voltage fl uctuation range and ripple voltagedo not exceed the input voltage range shown in specifi cations.!Please select an input power source with enough capacity, takinginto consideration of the start-up current (Ip), which fl ows when aDC-DC converter starts up.3 Series/RedundancyOperation3.1 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.Input Current [A]Input Voltage RangeIpInput Voltage [V]Fig.4.1 Input Current Characteristics(a)PowerSupply+-(b)PowerSupply+-Load5 CleaningPowerSupply+-LoadPowerSupplyFig.3.1 Examples of series operation3.2 Redundancy Operation!Parallel operation is not possible.!Redundancy operation is available by wiring as shown below.+-Load!If you need to clean the unit, please clean it under the followingconditions.Cleaning Method: lmmersion, Ultrasonic or Vapor CleaningCleaning agent: IPA (Solvent type)Cleaning Time: Within total 2 minutes for lmmersion, ultrasonicand vapor cleaning!Please dry the unit suffi ciently after cleaning.!If you do ultrasonic cleaning, please keep the ultrasonic output at15W/ or below.PowerSupply+-I1I36 Safety StandardsPowerSupply+-I2Fig.3.2 Redundancy operation!Even a slight difference in output voltage can affect the balancebetween the values of I1 and I2. Please make sure that the valueof I3 does not exceed the rated current for each power supply.Load!To apply for a safety standard approval using the power supply,please meet the following conditions. Please contact us for details.?Please use the unit as a component of an end device.?Reinforced insulation (250 VAC or less) is provided between theinput and output of this power supply. Limited to use when the inputvoltage of the device is 250 VAC or less.?Safety approved fuse must be externally installed on input side.?MH series has 2MOOP medical isolation grade.I3 [ Rated Current ValueMH-16
