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-1200-24 designed for?
The NPP-1200-24 is a 2-in-1 unit that can operate as either a battery charger or a power supply, with the mode selectable via jumper. It is intended for lead-acid battery applications and also suits systems that need a high-power 24V-class DC output from a single compact unit.
What are the main electrical ratings of the NPP-1200-24?
This model is rated at 1209.6W with a nominal output voltage of 28.8V and a rated current of 36A. It also supports adjustable output voltage and adjustable output current from 50% to 100%, which gives buyers more flexibility within the product's supported range.
Can the NPP-1200-24 be adjusted for different output voltage ranges?
Yes, within its own range. The NPP-1200-24's output voltage is adjustable from 21 to 42V via the potentiometer on the panel, with a default output of 28.8V. The 10.5 to 21V and 42 to 80V ranges belong to the 12V and 48V models of the NPP-1200 series.
What battery type is this model suitable for?
The NPP-1200-24 is specified as suitable for lead-acid batteries. It also includes a 3-stage charging curve in charging mode, which is a key feature buyers often look for in lead-acid charging applications.
Is the NPP-1200-24 suitable for demanding industrial or commercial environments?
Yes. It has a wide operating temperature range of -30°C to +70°C (output derating applies at higher temperatures, per the derating curve) and includes a thermal-controlled cooling fan to help reduce noise while managing heat. The unit also includes built-in protections for short circuit, overload, overvoltage, and overtemperature conditions.
What safety approvals and warranty does the NPP-1200-24 have?
This model is listed with CB, UL, DEKRA, and EAC approvals, including compliance with IEC/EN/UL62368-1 and EN60335-1/-2-29. It is backed by a 3-year warranty.
How does the NPP-1200-24 differ from a standard fixed-output power supply?
Unlike a standard fixed-output power supply, the NPP-1200-24 can serve as either a battery charger or a power supply in one unit. It also offers adjustable voltage and current, plus a 3-stage charging function for lead-acid battery applications, which makes it more versatile than a basic DC supply.
