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-1700-48 designed for?

The NPP-1700-48 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 intended for high-power 48V-class applications where flexibility between charging and DC output use is valuable.

What are the main output ratings of the NPP-1700-48?

This model is rated for 1680W output power with a nominal output voltage of 57.6V and rated current of 25A. It also supports adjustable output voltage (42 to 80V) and output current (12.5 to 25A) via built-in potentiometers.

Can the NPP-1700-48 be used with different battery chemistries?

Mean Well states that the NPP-1700 series is suitable for lead-acid batteries, including flooded, Gel and AGM types. Li-ion batteries are not listed, so check with Mean Well and your battery vendor before using other chemistries.

How does the NPP-1700-48 differ from a standard fixed-output power supply?

Unlike a standard power supply, this model supports both power supply mode and battery charging mode in a single unit. It also includes a 3-stage charging curve for charging applications, which is a key distinction for battery-focused use cases.

Is the NPP-1700-48 suitable for demanding temperature conditions?

Yes. The specified operating temperature range is -30°C to +70°C (with derating per the derating curve), which suits use in a wide range of environments. It also includes a thermal-controlled cooling fan to help reduce noise while managing heat.

What protection and safety features does the NPP-1700-48 include?

This model includes built-in protection for short circuit, overload, over voltage, and over temperature conditions. It is also listed with multiple safety approvals, including CB, UL, DEKRA and EAC, with compliance to IEC/EN/UL62368-1 and EN60335-1/-2-29.

Is the output adjustable on the NPP-1700-48?

Yes. Mean Well specifies adjustable output voltage via the front-panel potentiometer and adjustable output current from 50% to 100%. This helps buyers fine-tune the unit for application needs within the supported NPP-1700 series ranges.

What warranty is provided with the NPP-1700-48?

The NPP-1700-48 includes a 3-year warranty. That coverage aligns with the product's positioning as a high-power industrial battery charger and power supply solution.
