## **SPECIFICATIONS**
- *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%typ) load.
*5 Dimensions below PCB are not included.
- *6 Consult us about details.
- *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.
*7 The listed options may affect the published standard specifications. Please contact us for detailed product specifications and safety approvals. * All parameters not specially mentioned are measured at ACIN 230V, rated load and 25℃ of ambient temperature.
- When the load factor is low (Io=0~20%typ), the switching power loss is reduced by burst operation, which will cause ripple noise to go beyond the specifications.
* 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.
- *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 not comply with the IEC61000-3-2. Please contact us for details.
- Acoustic noise may be heard from the power supply when used for pulse load.

## **SPECIFICATIONS**
- *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=0～10%typ) load.
- *5 Dimensions below PCB are not included.
- *6 Consult us about details.
- *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.
*7 The listed options may affect the published standard specifications. Please contact us for detailed product specifications and safety approvals. * All parameters not specially mentioned are measured at ACIN 230V, rated load and 25℃ of ambient temperature.
- When the load factor is low (Io=0～10%typ), the switching power loss is reduced by burst operation, which will cause ripple noise to go beyond the specifications.
- 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.
- *3 Output power derating is required. Refer to "Derating"
- *4 Please contact us about another class.
- Acoustic noise may be heard from the power supply when used for pulse load.

## **Assembling and Installation Method**
- ■When the power supply is used with natural convection cooling, the standard mounting position is horizontal.
- ■AC voltage exists on the primary side. Therefore, in order to prevent electric shock, or to meet the leakage current requirements of the safety standard, you need to ensure the proper insulation distance.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
