Packing: According to your order,we can provide different cartons for you.
1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25oCof ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Line regulation is measured from low line to high line at rated load.
5. Load regulation is measured from 0% to 100% rated load.
6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meetsEMC directives.

Notes on choosing a switching power supply?
To increase the reliability of the S.P.S., we suggest users choose a unit that has a rating of 30% more power than actual need. For example, if the system needs a 100W source, we suggest that users choose a S.P.S. with 130W of output power or more. By doing this, you can effectively boost the reliability of the S.P.S. in your system. Make sure that the model qualifies for the safety standards and EMC regulations you need.
What are switching power supplies?
Switching power supplies input a commercial AC power supply (such as 110 VAC or 220 VAC), uses a high-speed semiconductor switching process to convert the input to high-frequency electric power, and yields a direct current (such as 24 VDC).
What about production process of switching power supply?
Maker Industrial and Trading Company started to run businiess since 2006, which is located in Wenzhou Yueqing - The world-famous city for low-voltage electric apparatus. We owns followed subsidiary corporations:
Yueqing Maker electric Co., Ltd. concentrates on Import and Export.
Yueqing MINGWEI Switching power supply Factory More than 20 years of production experience,focus on production and research and development of switch power supply.
