Description
NPP-750 is a miniaturized dual-purpose charger and power supply. In addition to being used as a three- stage charger for lead-acid batteries, it can also be used as a constant voltage output power supply to drive general load. The operating mode can be quickly switched by plugging or unplugging a connector on the front panel. Other features include: ultra-wide voltage output, adjustable voltage via VR on the panel (10.5~21V, 21~42V, 42~80V), adjustable charging current (50~100%), built-in intelligent fan with variable speed based on temperature to reduce noise and extend fan lifetime, -30~+70° C wide operating temperature, suitability for use in different environments, built-in remote ON/OFF control, compliance to IEC/EN/UL62368-1 and household EN60335-1/-2-29 dual safety, multiple built-in protections, and 3-year warranty. The NPP-750 is truly an intelligent, safe, and reliable universal dual- purpose charger and power supply with outstanding cost performance.

NOTE
| 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. Float charge voltage(Vfloat) adjustable via potentiomerter in battery charger mode.
4. This is MEAN WELL’s suggested range. Please consult your battery manufacturer for their suggestions about maximum charging current limitation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. The efficiency is measured at 16.8V charge voltage(12V model), 33.6V charge voltage(24V model), 67.2V charge voltage(48V model).
7. This protection mechanism is specified for the case the short circuit occurs after the charger is turned on.
8. The charger 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.”
