  1. 1. Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.
  2. 2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  3. 3. Derating may be needed under low input voltages. Please check the derating curve for more details.
  4. 4. The PSU is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 600mm*900mm metal plate with 1mm of thickness. 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 )
  5. 5. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

What is the Mean Well NPP-1200-48 designed for?

The NPP-1200-48 is a 2-in-1 unit that can operate as either a battery charger or a power supply, selectable by jumper. It is intended for applications that need high-output DC power and support for lead-acid battery charging in a single model.

What are the main output ratings of the NPP-1200-48?

This model is rated for 1200W class output, with a listed power rating of 1209.6W. It has a 57.6V output voltage and a rated output current of 18A.

Is the NPP-1200-48 suitable for battery charging as well as continuous DC output?

Yes. Mean Well specifies this model as a battery charger and power supply in one unit, with selectable operating modes. In charging mode, it uses a 3-stage charging curve and is stated to be suitable for lead-acid batteries.

How adjustable is the output on the NPP-1200-48?

The NPP-1200-48 has a wide adjustable output voltage range of 42 to 80V, set with the potentiometer on the panel (the 10.5 to 21V and 21 to 42V ranges belong to the 12V and 24V models). Output current is also adjustable from 50% to 100% (9 to 18A), which helps match the unit to different system requirements.

Can the NPP-1200-48 be used in demanding temperature conditions?

Yes. This model is specified for operation from -30°C to +70°C, with output derating at higher temperatures per the derating curve, which makes it suitable for challenging industrial and commercial environments. It also includes a thermal-controlled cooling fan to reduce noise when full cooling is not needed.

What protection and safety features does the NPP-1200-48 include?

The NPP-1200-48 includes built-in protection for short circuit, overload, over voltage, and over temperature conditions. It is also described as compliant with IEC/EN/UL62368-1 and EN60335-1/-2-29 related safety standards, with approvals including CB, UL, DEKRA, and EAC.

How does the NPP-1200-48 compare with a standard fixed-output power supply?

Compared with a basic fixed-output supply, the NPP-1200-48 stands out by combining charger and power supply functions in one model. It also offers adjustable voltage and current, lead-acid charging support, and a wide -30°C to +70°C operating temperature range.

What warranty is offered with the NPP-1200-48?

Mean Well lists this model with a 3-year warranty. That can be an important advantage for buyers specifying power equipment for long-service commercial or industrial use.
