Mean Well NPP-1200-48 1209.6W 48V Battery Charge& Power Supply 2-in-1, Selectable via Jumper

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.

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.

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.

The NPP-1200 series includes a very wide adjustable output voltage range, with front-panel potentiometer adjustment across 10.5 to 21V, 21 to 42V, or 42 to 80V ranges depending on model setting. Output current is also adjustable from 50% to 100%, which helps match the unit to different system requirements.

Yes. This model is specified for operation from -30°C to +70°C, 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.

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, EAC, CE, and UKCA.

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 wider operating temperature range than many general-purpose desktop supplies.

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.
