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-360-12TB designed for?
The Mean Well NPB-360-12TB is an NPB-360 series AC-DC battery charger built for 12V battery charging applications, with 304W maximum output power. It provides a 14.4V DC output at up to 20A, which makes it suitable for commercial and industrial battery charging use cases where a higher-power 12V charger is needed.
What are the main electrical specifications of the NPB-360-12TB?
This model is rated for 304W maximum output power and delivers 14.4V DC at up to 20A. It also features power factor correction and accepts universal AC input, which helps it fit a wide range of AC power environments.
Does the NPB-360-12TB support staged battery charging?
Yes. The NPB-360-12TB is described as supporting 2-stage or 3-stage charging, which is useful in battery charging applications that require a more controlled charging profile than a basic fixed-output supply. This makes it more application-specific than a standard AC-DC power supply.
Is this charger intended for demanding temperature environments?
Yes, this model has a specified operating temperature range from -30°C to +70°C, with output derating at higher ambient temperatures per the datasheet derating curve. That wide range makes it a strong fit for industrial or commercial environments where ambient conditions may be harsher than typical indoor electronics applications.
How does the NPB-360-12TB compare with a general-purpose 12V power supply?
The NPB-360-12TB is specifically identified as a battery charger rather than only a general-purpose DC power supply. Its 2-stage or 3-stage charging capability and 14.4V output make it better suited to battery charging applications than a standard fixed 12V supply.
What should buyers know about the physical details of this model?
The unit weighs 1.3 kg and measures 182.7 x 96 x 49 mm, which is useful when planning for panel, enclosure, or equipment integration. An optional mounting bracket is available separately for installation.
