Function Manual

1.Manual setting

1.1 2 or 3-stage selectable via DIP S.W on panel

1.2 Charging curve can be adjustable via DIP S.W on panel

◎ Suitable for lead-acid batteries (flooded, Gel and AGM) and Li-ion batteries (lithium iron and lithium manganese).
◎ Suitable for lead-acid batteries (flooded, Gel and AGM) and Li-ion batteries (lithium iron and lithium manganese).

※ The default curve is programmable, whereas other pre-defined curves can be activated by the means of the DIP S.W; This series provides 2 or 3 stage charging curve please refer to the table below and the Mechanical Specification.

2.Programmable charging curve

Charging Curve can be set via SBP-001 with 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 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 CAN Bus Interface. (2) Please contact MEAN WELL for more details.

※ Software Interface:

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

※ Function Description:
a. NPB-1200 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-1200 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-1200’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:

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-1200 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(CAN Bus).
T1(Typ.): Maximum ambient temperature of 100% output current. T2(Typ.): T1+5.

5.CANBus communication interface

CAN Bus 2.0B version, Can control, setting and monitoring that including output charging voltage, output charging current,internal temperature and DC output ON/OFF……and so on, please refer to the user manual for more details.

6.Charger OK Signal

Charger OK signal is a TTL level signal. The maximum sourcing current is 10mA.

7.Battery Full Signal

Battery full signal is a TTL level signal. The maximum sourcing current is 10mA.

8.Remote ON-OFF Control

The NPB-1200 can be turned ON/OFF by using the “Remote Control” function.

9.Temperature compensation(3 stage only)

Temperature compensation function to prolong battery life for lead-acid batteries. Temperature compensation range is 0 ~ 40. The battery temperature sensor comes along with the charger can be connected to the unit to allow temperature compensation of the charging voltage.
If the sensor is not used, the charger works normally.

10. DC Output Side LED Indicators & Corresponding Signal at Function

Pins

Mechanical Specification
※ Intelligent Battery Charger model

Note1: Non-isolated signal, referenced to [GND(signal)].
Note2: Isolated signal, referenced to GND-AUX

Accessory List
※ NTC Sensor and Remote Control mating along with NPB-1200 (Standard accessory)
