1. Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.

2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.℃

3. Derating may be needed under low input voltages. Please check the derating curve for more details.

4. PSU The is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on

600 900 For guidance on how to a mm* mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives.

perform these EMC tests, please refer to EMI testing of component power supplies. (as available on http://www.meanwell.com)

5. The ambient temperature derating of 3.5 /1000m with fanless models and of 5 /1000m with fan models for operating altitude higher than 2000m(6500ft).℃℃
