While Low-Voltage BMS is designed for an input voltage of 11–60 V DC, testing has
confirmed that the unit experiences no degradation when using an input voltage up
to 68 V DC. However, for applications that exceed 60 V DC, please consider Nuvation
Energy High-Voltage BMS or contact support@nuvationenergy.com.
The +VPOWER input current depending on the loads the Low-Voltage BMS is driving.
Without contactors, the Low-Voltage BMS draws approximately 70 mA at 48 V DC.
With all contactors connected and energized, it can draw up to 1.25 A at 48 V DC.
Nuvation Energy BMS does not include an internal free-wheeling protection diode on
contactor coil-driver circuits, as it has been found to cause premature contactor
failure.
