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.
Software Interface:

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)

The LED will flash with the red light when the internal temperature reaches 95; under this condition, the unit still operates normally without entering OTP. (In the meantime, an alarm signal will be sent out through the CANBus interface.)

Description
A1
CANBus interface address line(A1). Referenced to GND(Signal) Pin4.(Note.1)
A0
CANBus interface address line(A0). Referenced to GND(Signal) Pin4.(Note.1)
+3.3V
+3.3V voltage output, referance to GND(pin 4).
GND(Signal) CANBus interface address lines GND.
Battery Full Signal, referenced to GND-AUX(Pin 9 & 10).
Battery Full
The Signal is a TTL level signal. The maximum sourcing current is 10mA and only for output.(Note.2) Low (-0.5 ~ 0.5V) : When the battery is charging.
High (4.5 ~ 5.5V) : When the battery is full.
Charger OK Signal, referenced to GND-AUX(Pin 9 & 10).
Charger OK The Signal is a TTL level signal. The maximum sourcing current is 10mA and only for output.(Note.2) Low (-0.5 ~ 0.5V) : When the charger fails or the protect function is activating.
High (4.5 ~ 5.5V) : When the charger is working properly.
Remote ON-OFF
Remote charger ON/OFF Function. The charger can turn the output ON/OFF by dry contact between Remote ON-OFF and +12V-AUX.(Note.2) Short (10.8 ~ 13.2V) : Charger ON ; Open (-0.5 ~ 0.5V) : Charger OFF ; The maximum input voltage is 13.2V.
+12Vaux It is controlled by the Remote ON-OFF control.
GND-AUX The signal return is isolated from the output terminal. (+V & -V)
CANH
For CANBus model: Data line used in CANBus interface. (Note.2).
CANL
For CANBus model: Data line used in CANBus interface. (Note.2).
NTC(RTH+) Temperature sensor(NTC, 5KOhm) comes along with the charger can be connected to the unit to allow temperature
NTC(RTH-) compensation of the charging voltage for lead-acid batteries. Temperature compensation range is 0 ~ 40(3 stage only).
Note1: Non-isolated signal, referenced to [GND(signal)]. Note2: Isolated signal, referenced to GND-AUX
