- *1 Consult us about dynamic load and input response. Measure the output voltage by using the average 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 0.1μF placed at 150 mm from the output terminals by a 20MHz oscilloscope or a ripple-noise meter equivalent to Keisoku-GikenRM104. 

   - When the load factor is low (Io=0~20%Atyp), the switching power loss is reduced by burst operation, which will cause ripple noise to go beyond the specifications. 

- *3 Output power derating is required. Refer to "Derating" 

- *4 Consult us about details. 

- *5 The listed options may affect the published standard specifications. Please contact us for detailed product specifications and safety approvals. 

- *6 Please contact us about another class. When two or more units are operating it may not comply with the IEC61000-3-2. Please contact us for details. 

- *7 Dimensions below PCB are not included. 

- 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 voltage ranges. 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.
