Notes

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
2. Ripple & noise are measured at 20 MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1 uf & 47 uf parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360 mm x 360 mm metal plate with 1 mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to "EMI testing of component power supplies." (as available on www.meanwell.com)
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m (6500 ft).
7. Product Liability Disclaimer: For detailed information, please refer to MEAN WELL Service Disclaimer.

Derating Curve

The derating curve shows the relationship between ambient temperature and the maximum allowable load percentage. The power supply can operate at 100% load up to an ambient temperature of 50°C, after which the load capacity decreases linearly to 0% at 65°C.

Static Characteristics

The static characteristics graph illustrates the relationship between input voltage and output load percentage. The power supply maintains 100% load capacity across the input voltage range of 90-264 VAC (at 60Hz).

Function Manual: External Voltage Control

The output voltage can be trimmed externally using a DC control signal. The relationship between the external voltage (DC) and the output voltage (%) is shown. A 1-5.5V DC external voltage signal applied to the PV and -V terminals allows for output voltage adjustment from 20% to 110% of the rated output voltage.

The graph shows that an external voltage of 1V DC corresponds to 20% output voltage, and 5.5V DC corresponds to 100% output voltage. The relationship is described as non-linear.

Another graph illustrates the output current (%) versus output voltage (%). This indicates that as the output voltage increases beyond a certain point (approximately 105-110% of rated), the output current is limited to protect the unit.
