Test conditions and notes5

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. Derating may be needed under low input voltages. Please check the derating curve for more details.
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. 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-1200-12 designed for?

The NPP-1200-12 is a 2-in-1 unit that can operate as either a battery charger or a power supply, depending on the selected mode. It is aimed at applications that need high output power in a miniaturized form factor. This model is also suitable for lead-acid battery charging.

What are the main output specifications of the NPP-1200-12?

This model is rated at 1176W with a nominal 14.4V output and 70A rated current. It also supports adjustable output voltage and output current via front-panel controls. That makes it useful where the load or charging profile needs some flexibility within the model's supported range.

Can the NPP-1200-12 be used only as a charger, or also as a power supply?

It is built for both roles. The unit supports battery charger mode with a 3-stage charging curve, and it can also be used as a standalone power supply. This dual-purpose design is one of the main differences between the NPP-1200-12 and a basic fixed-function supply.

What battery types is the NPP-1200-12 compatible with?

Based on the provided specifications, this model is suitable for lead-acid batteries. No other battery chemistries are stated in the product data. For that reason, buyers should match it specifically to lead-acid charging applications.

Is the output adjustable on the NPP-1200-12?

Yes. The product listing states that both output voltage and output current are adjustable, with current adjustable from 50% to 100%. The voltage adjustment ranges listed for the NPP-1200 series are ultra-wide and selected to suit the operating range of the unit.

Is the NPP-1200-12 suitable for demanding temperature environments?

Yes, this model is rated for operation from -30°C to +70°C. It also includes a thermal-controlled cooling fan to help reduce noise while supporting thermal management. Output derating applies at higher temperatures, so check the derating curve for your installation.

What protection and compliance features does the NPP-1200-12 include?

The NPP-1200-12 includes protection for short circuit, overload, over voltage, and over temperature conditions. It is also described as compliant with IEC/EN/UL 62368-1 and EN60335-1/-2-29 related safety standards, with approvals including CB, UL, DEKRA, and EAC. The unit is backed by a 3-year warranty.
