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 radiation tests require an additional 13*26*30 NIZN magnetic clasp or magnetic ring to the output line for CLASS B and without NIZN magnetic clasp or magnetic ring for CLASS A. 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-750-48 used for?

The NPP-750-48 is a dual-purpose unit that can operate as either a battery charger or a power supply, with the mode selectable by jumper. It is aimed at professional and industrial use cases such as electric scooters, mobile robots, floor scrubbers, security systems, communication equipment, and industrial control systems.

Is the NPP-750-48 a battery charger, a power supply, or both?

This model is designed to serve both roles in a single product. It can be used in charger mode for supported battery-charging applications or in power supply mode when regulated DC output is needed for equipment.

What output does the NPP-750-48 provide?

This model is a 48V-class unit with a listed output voltage of 57.6V and a rated current of 11.3A. It is rated at 759.36W and includes adjustable output voltage and output current controls.

What battery type is the NPP-750-48 suitable for?

Based on the provided product data, the NPP-750-48 is suitable for lead-acid batteries. It also includes a 3-stage charging curve for charging-mode operation.

Can the NPP-750-48 be used in demanding environments?

Yes. The unit has a wide operating temperature range of -30°C to +70°C (with derating per the derating curve), which makes it suitable for tougher indoor or protected equipment environments. It also uses a built-in cooling fan controlled by internal temperature for thermal management.

What protection and compliance features does the NPP-750-48 include?

The NPP-750-48 includes built-in protection for short circuit, overload (in power supply mode), over voltage, and over temperature conditions. It is also listed with multiple safety approvals including CB, UL, Dekra, J62368-1, and EAC, with compliance to 62368-1 and 60335-1/-2-29 standards.
