File Name:NPB-450-SPEC 2023-01-16 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 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. 450W High Reliable Ultra Wide Output Range Intelligent Battery Charger NPB-450 series ※ Function Description: Charging curve adjustable 2 or 3-stage selectable Model selection Charging timeout setting ※ ft are So w Interface: NPB-450 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 is detected. 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)

(1) Default factory setting is OFF via DC output side DIP S.W, Follow steps A1~A6 below to enable the setting. (Battery Management System).(2) Auto ranging function should use together with Lithium batteries and BMS (3) Do not exceed the output voltage and current ranges as specified in the NPB-450 specifications (please refer to page 2). File Name:NPB-450-SPEC 2023-01-16 ※ 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 battery) Set DIP S.W all in the "OFF" position(Default). Applying AC main and swith on under remote OFF. Within 15 seconds , set DIP S.W, all in the "ON" position and all back in the "OFF" again. The green LED flashes 3 times means the process is successfully done. Restart the NPB-450 to load smart charging curve setting. (AC input on/off or swith on/off on AC input side) Pin 7 & 8 put on jumper.

Applying AC main under remote OFF condition. Switch the DIP switch from all ON to all OFF, and then again, back to all ON in 15 seconds. If LED flashes in GREEN for 3 times, it means the setting is succeeded. Remote ON the unit, and it's now back to factory setting. ※ When using the auto ranging charging curve function, please pay attention to the following: Step Action Step Action AC INPUT AC INPUT or Note Note
