## ※ **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 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/NPB-450-xxNFC 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/NPB-450-xxNFC'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)

MEAN WELL **450W High Reliable Ultra Wide Output Range Intelligent Battery Charger NPB-450  series** ~~ee~~ 

※ When using the auto ranging charging curve function, please pay attention to the following:

(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).
