There is a possibility that an internaldevice is damaged when the specification is exceeded. Pleasecontact us about the detail.*6 Applicable when remote control (optional) is added.*7 Please contact us about dynamic load and input response.? 226 ?Example recommended EMI/EMC filterNAC-06-472High voltage pulse noise type : NAP seriesLow leakage current type : NAM series* A higher current rating EMI/EMC filtermay be recommended in view of theother devices that could be connectedin parallel with the power supply.*8 Please contact us about another class.* To meet the specifications. Do not operate over-loadedcondition.* Parallel operation is not possible.* Derating is required when operated with chassis and cover.* Sound noise may be generated by power supply in case ofpulse load.
