Mean Well NPB-750-48 Battery Charger 759.4W 48V - Suitable for Lead...
Overview
NPB-750-48 is the model of this series: typical efficiency 93%.
NPB-750 is a miniaturized, versatile, and ultra-wide voltage intelligent charger. It utilizes a fully digital control design with automatic battery voltage detection technology, with five key features including intelligent, versatile, user friendly, safe, and compact. The series have four models with output voltage ranges of 10.5~21V, 21~42V and 42~80V respectively. The charging voltage range of each model is wide enough to cover a variety of different battery voltages and battery chemistries, and there is a built-in intelligent voltage detection charging mode (Note this mode is set to OFF by factory default and is suitable for lithium batteries with BMS only). The NPB-750 can pair with MEAN WELL’s SBP-001 programmer for digital configuration, such as adjust charging voltage/current, and set charging cycle time to protect battery lifetime. Through the user-friendly DIP S.W. on front panel, user may also directly adjust the 2/3 stage charging, current (50~100%), and select between the 4 types of preset charging curves. In addition, a CANBus communication protocol is built in to meet professional applications, which allows remote controlling and monitoring for the status of the charger. In terms of safety, it has intelligent detection for proper battery voltage and connection as well as protection from reverse polarity. It passes ITE IEC/EN/UL62368-1 and household appliances EN60335-1/-2-29 dual safety and 3-year warranty to guarantee reliable operation. The NPB-750 is truly an intelligent, safe, and reliable universal charger with outstanding cost performance.

NOTE
- 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. This is the range when programming Vboost or Vfloat by using SBP-001, the smart battery charging programmer. 4. Refer to derating curve. 5. This is MEAN WELL's suggested range. Please consult your battery manufacturer for their suggestions about maximum charging current limitation. 6. Derating may be needed under low input voltages. Please check the derating curve for more details. 7. The efficiency is measured at 16.8V charge voltage(12V model), 33.6V charge voltage(24V model), 67.2V charge voltage(48V model). 8. This protection mechanism is specified for the case the short circuit occurs after the charger is turned on. 9. Each model incorporates a MCU-controlled dynamic over voltage protection, which is about 125% of Vboost over Constant Current stage and Constant Voltage stage whereas 125% of Vfloat over Float stage. 10. 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. 11. 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).
