Description
NPP-450 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, 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 IEC/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

-
Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.
-
All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
-
Float charge voltage(Vfloat) adjustable via potentiomerter in battery charger mode.
-
This is MEAN WELL’s suggested range. Please consult your battery manufacturer for their suggestions about maximum charging current limitation.
-
Derating may be needed under low input voltages. Please check the derating curve for more details.
-
The efficiency is measured at 16.8V charge voltage(12V model), 33.6V charge voltage(24V model), 67.2V charge voltage(48V model), 84V charge voltage(72V model).
-
This protection mechanism is specified for the case the short circuit occurs after the charger is turned on.
-
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 “EMI testing of component power supplies.” (as available on http://www.meanwell.com) -
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).
