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. Float charge voltage(Vfloat) adjustable via potentiomerter in battery charger mode. 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.
7. This protection mechanism is specified for the case the short circuit occurs after the charger is turned on. **
