  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-1700-24 designed for?

The NPP-1700-24 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 higher-power 24V applications where buyers want one model that can support charging mode or regulated DC output mode. This makes it relevant for commercial and industrial use cases that need flexibility within a single platform.

What are the main output ratings of the NPP-1700-24?

This model is rated for 1680W output power and 50A rated current. The listed output voltage for this version is 28.8V, which aligns with 24V system applications. It also features adjustable output voltage and output current via front-panel controls.

Can the NPP-1700-24 be used with different battery chemistries?

The product description states that it is suitable for lead-acid batteries, including flooded, Gel and AGM types; other chemistries such as li-ion are not listed. It also includes a 3-stage charging curve when used in charging mode. Buyers should confirm their battery's charging requirements with the battery vendor and Mean Well.

How adjustable is the NPP-1700-24 for different output requirements?

The NPP-1700 series offers ultra-wide output voltage ranges, with front-panel adjustment ranges of 10.5 to 21V, 21 to 42V, and 42 to 80V depending on the version. This NPP-1700-24 version is the 24V class model with a listed 28.8V output, adjustable from 21 to 42V. Output current is also adjustable from 50% to 100% (25 to 50A), which helps buyers match the unit to their application requirements.

Is the NPP-1700-24 suitable for harsh or demanding environments?

This model is specified for operation from -30°C to +70°C (with derating per the derating curve), which is a wide operating temperature range for demanding environments. It also uses a thermal-controlled cooling fan to reduce noise while supporting thermal management. For buyers evaluating durability, the unit also includes built-in protections for short circuit, overload, over voltage, and over temperature.

What certifications and warranty does the NPP-1700-24 include?

The NPP-1700-24 is described as complying with IEC/EN/UL 62368-1 and household EN60335-1/-2-29 safety standards. The listed approvals include CB, UL, DEKRA and EAC. Mean Well also specifies a 3-year warranty for this model.
