NOTE | 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. Refer to derating curve. 4. This is MEAN WELL's suggested range. Please consult your battery
manufacturer for their suggestions about maximum charging current
limitation. 5. Derating may be needed under low input voltages. Please check
the derating curve for more details. 6. This protection mechanism is specified for the case the short
circuit occurs after the charger is turned on. 7. 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
