Product Usage Instructions

AC Input Side
The AC input side of the NPB-1700 series is where the charger is connected to the power source. Ensure that the charger is plugged into a compatible AC power outlet.

DC Output Side
The DC output side of the NPB-1700 series is where the charger connects to the battery. Make sure to connect the charger’s output terminals to the appropriate terminals on the battery, ensuring correct polarity.

Charging Parameters Adjustment
The NPB-1700 series charger allows for adjustable charging parameters. This can be done in two ways:

• Programmable: Connect the charger to a computer and use the SBP-001 software to set the constant current (CC), taper current (TC), constant voltage (CV), and float voltage (FV).
• Manual Setting: Use the DIP switches on the panel to select one of the four built-in charging curves. Refer to the function manual for more details on each curve.

Auto Ranging for Function Charging
The NPB-1700 series charger supports auto-ranging for function charging. Please refer to the function manual for detailed instructions on how to use this feature.

CANBUS Interface
The charger is equipped with a CANBUS interface for control, setting, and monitoring. The charging current can be adjusted between 50% and 100% using the potentiometer on the panel. This feature is only available in auto-ranging mode.

SPECIFICATION

NOTE

1. Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.
2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
3. This is the range when programming Voost or Viloat by using SBP-001, the smart battery charging programmer.
4. Refer to derating curve.
5. This is MEAN WELL’s suggested range. Please consult your battery manufacturer for their suggestions about maximum charging current limitation.
6. Derating may be needed under low input voltages. Please check the derating curve for more details.
7. The efficiency is measured at 16.8V charge voltage(12/ model), 33.6V charge voltage(24V model), 67.2V charge voltage(48V model).
8. This protection mechanism is specified for the case the short circuit occurs after the charger is turned on.
9. Each model incorporates a MCU-controlled dynamic over voltage protection, which is about 125% of Voost over Constant Current stage and Constant Voltage stage whereas 125% of Vfloat over Float stage.
10. The charger is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 600mm*900mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)
11. The ambient temperature derating of 3.5 C/1000m with fanless models and of 5 C/1000m with fan models for operating altitude higher than 2000(6500ft).

• 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 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.

Auto Ranging for Charging (Default non-Auto ranging)

• Function Description:
  • NPB-1700 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)
  • When operating in auto ranging mode , NPB-1700 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.
  • While under auto ranging mode, NPB-1700’s built-in MCU will adjust charging voltage. There is no potentiometer for voltage adjustment on the front panel.
  • 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. (Battery M
2. Auto ranging function should use together with Lithium batteries and BMS anagement System).
3. Do not exceed the output voltage and current ranges as specified in the NPB-1700 specifications (please refer to page 2).

• 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)
