4.1
Power consumption of NM350
The device uses power supply voltage in the range from +9 V to +36 V from PWR connector.
Consideration should be given to certain requirements, which are essential for ensuring
stability and reliability. In Table 4-1 and Table 4-2 contain values of the maximum allowable
voltages and currents, which if exceeded, could lead to module damages. Power supply sources,
which are to be used with NM350, should be checked in order to meet these requirements.
