| Notes & safety | |
| Notes: | 1. Products with a shell are also available. To indicate a product with shell, add “-C” suffix to model number. 2.Under any conditions, the total power of the product should not exceed the rated power. When the output voltage is increased, the total output power cannot exceed the rated output power, when the output voltage is decreased, the output current cannot exceed the rated output current. 3. When measuring the full load efficiency, the fan should be connected to an external power supply. Fan loss is not included in the input power. 4. Output voltage accuracy: including setting error, line regulation, load regulation. 5. For fan power connection method, please refer to pin 6, 7 of the dimension drawing. 6. The “tip and barrel method” is used for ripple and noise test, output parallel 10uF electrolytic capacitor and 0.1uF ceramic capacitor. Please contact factory for more information. 7. This product is Listed to applicable standards and requirements by UL. 8. The power supply is considered a component as part of a system. All EMC items are tested on a metal plate (360mm x 360mm x 1mm). Power supply should be combined with final equipment for EMC confirmation. 9. Category I products with PE, category II products without PE. 10. Ambient temperature derating of 5°C/1000m is needed for operating altitude greater than 2000m 11. In order to improve the efficiency at light load, there will be audible noise generated, but it does not affect product performance and reliability 12. Product customization service is available. Contact factory for more information. 13. The output voltage can be adjusted by the ADJ, clockwise to decrease. 14. Warning: Use double fuses, please disconnect the power before maintenance and replacement 15. Products should be classified according to ISO 14001 and related environmental laws and regulations and should be handled by qualified units. 16. Power supply is considered a component which will be installed into final equipment. All EMC tests should be confirmed with final equipment. Contact factory for more information. 17. The surface of the product should be kept a safe distance from the customer system (recommended ≥3mm), if not please contact factory. *Due to advances in technology, specifications subject to change without notice. |
