NOTE	Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature. Refer to derating curve. This is MEAN WELL’s suggested range. Please consult your battery manufacturer for their suggestions about maximum charging current limitation. Derating may be needed under low input voltages. Please check the derating curve for more details. This protection mechanism is specified for the case the short circuit oocurs after the charger is turned on. The charger 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) Product Liability Disclaimer : For detailed information, please refer to https://www.meanwell.corn/serviceDisclaimer.aspx
