Hauj lwm

NPB-450 is a miniaturized, versatile, and ultra-wide voltage intelligent charger. It utilizes a fully digital control design with patented 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, 42~80V, and 54~100V 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-450 can pair with MEAN WELL’s SBP-001 programmer for digital configuration, such as select 2/3 stage charging, 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 IC/EN/UL62368-1 and household appliances EN60335-1/-2-29 dual safety and 3-year warranty to guarantee reliable operation. The NPB-450 is truly an intelligent, safe, and reliable universal charger with outstanding cost performance.

Muaj nuj nqi Piav Qhia:

SBP-001 is a programmer, particularly for MEAN WELL’s various programmable battery charger models to program the parameters of charging curves, such as the 2 or 3 stage selectable, 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 SBP-001 programmer and the computer; all of the setups are able to be finished easily by the means of the specific software.
Note:(1) Tapper current(TC) default is 10%, can be fine tuned from 2% to 30% by SBP-001 with computer or CANBus Interface.
(2) Please contact MEAN WELL for more details.

3. Auto Ranging for Charging (Default non-Auto ranging)

※ Function Description:

a. NPB-450 has built-in auto ranging mode.
(Note this mode is set to OFF by factory default and is suitable for lithium batteries with BMS only)

b. When operating in auto ranging mode , NPB-450 will automatically detect the voltage of battery that is connected and adjust charging voltage accordingly. It will not start charging unit appropriate battery voltage yog kuaj pom.

c. While under auto ranging mode, NPB-450’s built-in MCU will adjust charging voltage. There is no potentiometer for voltage adjustment on the front panel.

d. While under auto 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:

Input-Output Side

  1. Default factory setting is OFF via DC output side DIP S.W, Follow steps A1~A6 below to enable the setting.
  2. Auto ranging function should use together with Lithium batteries and BMS (Battery Management System).
  3. Do not exceed the output voltage and current ranges as specified in the NPB-450 specifications (please refer to page 2).

4. Auto Derating function

※ Covered by over temperature protection, auto de-rating function works under operation either in charging curve (2 or 3 stage) or under control by communication protocol(CANBus).

T1(Typ.): Maximum ambient temperature of 100% output current.
T2(Typ.): T1+5℃.
