For the EC350 and LC350 HMS recommends that you size your power supply to provide at least 24W of power to each Netbiter device.
While the average power consumption is typically much lower, around 6W, the peak power consumption can be around 17W. This high peak consumption can be seen when the device is operating on 2G cellular networks with poor signal strength.
Reference the label on the back of the device for the voltage range. We have updated the internal supply to work as low as 9v. This is to allow the device to stay active during voltage drops seen on some devices such as a starting generator. The total voltage range for newer devices is 9-32v vs 12-48v on older models.
We’ve provided feedback to the product development group that the documentation in the installation guide, the manual, online and on the product are providing different numbers and we hope to see that information corrected in the near future.
