Measure the output voltage by using theaverage mode of the tester to deal with the burst operation at low (Io=0～20%Atyp) load.*2 This is the result of measurement of the testing board with capacitors of 47μF and 0.1μFplaced at 150 mm from the output terminals by a 20MHz oscilloscope or a ripple-noisemeter equivalent to Keisoku-GikenRM104.When the load factor is low (Io=0～20%Atyp), the switching power loss is reduced by burstoperation, which will cause ripple noise to go beyond the specifications.*3 Output power derating is required. Refer to "Derating"*4 Please contact us about another class. When two or more units are operating it may notcomply with the IEC61000-3-2. Please contact us for details.WMA-4*5 Consult us about details.*6 The listed options may affect the published standard specifications. Please contact us fordetailed product specifications and safety approvals.* All parameters not specially mentioned are measured at ACIN 230V, rated load and 25℃of ambient temperature.* Do not use the power supply in overcurrent conditions or in unspecified input voltageranges. Otherwise the internal components may be damaged.* Parallel operation is not possible with this model.* Acoustic noise may be heard from the power supply when used for pulse load.May ? 732 09, ? 2025
