NOTE

Modification for charger specification may be required for different battery specifications. Please contact the 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.
Float charge voltage(Vfloat)is adjustable via a potentiometer in battery charger mode.
This is MEAN WELL’s suggested range. Please consult your battery manufacturer for their suggestions about the maximum charging current limitation.
Derating may be needed under low input voltages. Please check the derating curve for more details.
The efficiency is measured at 16.8V charge voltage(12V model), 33.6V charge voltage(24V model), and 67.2V charge voltage(48V model).
This protection mechanism is specified for the case the short circuit occurs after the charger is turned on.
The charger is considered a component that will be installed into the final equipment. All the EMC tests are been executed by mounting the unit on a 600mm*900mm metal plate with 1mm of thickness. 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitudes higher than 2000m(6500ft).
