Description

This power supply is ideally suited for use with amplifier projects. The regulated 12 VDC, 4.2A design is capable of delivering 50watts of output. Overload, over voltage, and short circuit protection is built-in, shutting down the power supply to prevent damage and then restoring power upon recovery.

NOTE 1. All parameters NOT specially mentioned are measured at 230VAC input,rated load and 25℃ of 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. For the request of GB4943.1, the power supply is only suitable for use in the altitude 2000m below and the non tropical climate condition. 7. 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 meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)
