  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-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.
