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-1700-12 designed for?

The NPP-1700-12 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 built for high-power 12V applications that need up to 1428W output in a single unit.

Can the NPP-1700-12 be used with different battery types?

Mean Well specifies this model as suitable for lead-acid batteries, including flooded, Gel and AGM types. It also includes a 3-stage charging curve when used in charging mode.

What are the main output ratings of the NPP-1700-12?

This model is rated at 1428W with a nominal output voltage of 14.4V and a rated current of 85A. It is part of the NPP-1700 series, which provides high-output performance for demanding DC power and charging applications.

Is the output adjustable on the NPP-1700-12?

Yes. The product description states that both output voltage and output current are adjustable via front-panel controls. Output current can be adjusted from 50% to 100% (42.5 to 85A), and output voltage from 10.5 to 21V on this 12V model.

What protection features are built into the NPP-1700-12?

The NPP-1700-12 includes multiple built-in protections for short circuit, overload, over voltage, and over temperature. These protections help support reliability in industrial and commercial power applications.

Is the NPP-1700-12 suitable for demanding temperature environments?

Yes. Mean Well rates this model for operation from -30°C to +70°C (with derating per the derating curve), which makes it suitable for a wide range of environments. It also uses a thermal-controlled DC fan to help reduce noise while managing cooling.

How does the NPP-1700-12 differ from a standard fixed-function power supply?

Unlike a standard single-purpose power supply, the NPP-1700-12 can serve as either a battery charger or a power supply in one unit. It also adds adjustable voltage and current, support for lead-acid batteries, and a built-in 3-stage charging function.

What safety approvals and warranty does the NPP-1700-12 include?

This model is listed with CB, UL, DEKRA and EAC safety approvals, including IEC/EN/UL62368-1 and EN60335-1/-2-29 coverage. Mean Well also backs the NPP-1700-12 with a 3-year warranty.
