Test conditions and notes7

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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ

What is the Mean Well NPB-240-12AD1 used for?

The NPB-240-12AD1 is an AC-DC battery charger designed for 12V battery charging applications where up to 205.2W of charging power is needed. It is suited to buyers looking for a cable-type charger with an Anderson-style connector and controlled 2-stage or 3-stage charging behavior.

What are the output rating and charging capacity of this model?

This model is rated for 205.2W maximum power and provides a 14.4V DC default boost charge voltage at 13.5A. Those ratings make it a higher-capacity option for 12V battery charging compared with lower-wattage chargers in the same category.

Does the NPB-240-12AD1 support multi-stage charging?

Yes, the product description specifies 2-stage or 3-stage charging. That makes it relevant for buyers who need a charger designed specifically for battery charging rather than a basic fixed-output power supply.

What input power range does this battery charger support?

The NPB-240-12AD1 has universal AC input, specified as 90-264VAC (or 127-370VDC). This is useful for commercial and industrial buyers who need the same charger model across different AC supply environments.

Is this charger suitable for demanding environments?

It is rated for operation from -30°C to +70°C, with output derating at higher ambient temperatures (see the derating curve), which is a wide working temperature range for industrial use. Buyers evaluating environmental durability should also note that the unit weighs 1.3 kg, supporting portable use cases without being overly bulky.

What connector type does the NPB-240-12AD1 include?

This specific model includes an Anderson connector as stated in the product name and description. That is an important compatibility detail for buyers who need this exact connector style on the charger side.
