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)
