Description

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 intelligent, versatile, user-friendly, safe, and compact. The series has 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 adjusting charging voltage/current and setting charging cycle time to protect battery lifetime. Through the user-friendly DIP S.W. on the front panel, the 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 to meet professional applications, which allows remote controlling and monitoring of 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 a 3-year warranty to guarantee reliable operation. The NPB-750 is truly an intelligent, safe, and reliable universal charger with outstanding cost performance.

Programmable charging curve

Charging Curve can be set via SBP-001 with a computer

Step 1
Hardware configuration

Step 2
Connect to software for setting

Function Description:
SBP-001 is a programmer, particularly for MEAN WELL’s various programmable battery charger models to program the parameters of charging curves, such as Constant current (CC), tapper current(TC), Constant voltage (CV), float voltage (FV), Charging time out and so on, to accommodate the diversified battery specification in industry. With the design accounting for simplicity and convenience, users can easily configure MEAN WELL’s programmable battery chargers with the SBP-001 programmer and the computer; all of the setups can be finished eausingns of the specific software.

Note:

1. The Tapper current(TC) default is 10%, which can be fine-tuned from 2% to 30% by SBP-001 with a computer or CANBus Interface.
2. Please contact MEAN WELL for more details.

Software Interface

Auto Ranging for Charging (Default non-auto ranging)

• Function Description:
  • NPB-750 has a built-in auto-ranging mode. (Note this mode is set to OFF by factory default and is suitable for lithium batteries with BMS only)
  • When operating in auto-ranging mode, NPB-750 will automatically detect the voltage of the battery that is connected and adjust the charging voltage accordingly. It will not start charging unit the appropriate battery voltage is detected.
  • While under the auto-ranging mode, NPB-750’s built-in MCU will adjust the charging voltage. There is no potentiometer for voltage adjustment on the front panel.
  • While und auto-ranging ranging mode, the charging current can be adjusted between 50~100%. (The charging current can not be adjusted via potentiometer while not operating in auto-ranging mode)
• When using the auto-ranging charging curve function, please pay attention to the following:

1. The default factory setting is OFF via DC output side DIP S.W., Follow steps A1~A6 below to enable the setting.
2. (Battery M (2) Auto ranging function should be used together with Lithium batteries and BMS Management System).
3. Do not exceed the output voltage and current ranges as specified in the NPB-750 specifications (please refer to page 2).

• Auto Ranging function by DIP S.W Setting (Please make sure that the battery is lithium battery and must be matched with BMS before using. Auto ranging function is prohibited for non-lithium batteries)

Back to non-auto ranking as follows:

Auto Derating function

• Covered by over-temperature protection, the auto de-rating function works under operation either in the charging curve (2 or 3 stages) or under control by communication protocol(CANBus).
  • T1(Typ.): Maximum ambient temperature of 100% output current.
  • T2(Typ.): T1+5℃.
