Description
NPP-450 is a miniaturized dual-purpose charger and power supply. ln 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, 54~100V), 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 lEC/EN/UL62368-1 and household EN60335-1/-2-29 dual safety, multiple built-in protections, and 3-year warranty. The NPP-450 is truly an intelligent, safe, and reliable universal dual-purpose charger and power supply with outstanding cost performance.

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

voltage(72V 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 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 “EMl testing of component power supplies.”
