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. This is the range when programming Vboost or Vfloat by using SBP-001, the smart battery charging programmer.
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. Each model incorporates a MCU-controlled dynamic over voltage protection, which is about 115% of Vboost over Constant Current stage and Constant
Voltage stage whereas 115% of Vfloat over Float stage.
8. The battery charger is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the
EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
