Software-Defined Power Management Unit

Whether enabling free Wi-Fi for buses, or maintaining surveillance on maritime deployments, you need to rely on battery power. Any battery-powered deployments will face the following challenges:

Voltage Fluctuation
Battery power does not provide stable voltage, this could make devices function unreliably or shut down altogether.

Inability to Troubleshoot
In the event that devices lose power, there is no information on how the battery has been performing up to that point.

Battery Drainage
If batteries are excessively drained, they will be unable to start up the vehicle. Overdraining batteries will also damage them.


Voltage Regulation

The SD-PMU can take power from sources with low or fluctuating voltage and turn them into a reliable streams of 52V power. Each device can support 2 power inputs and 4 power outputs.

Remote Voltage Monitoring

The SD-PMU records battery voltage information and sends it over the IoT Cloud for remote monitoring. In case the SD-PMU cannot reach the IoT Cloud, it will locally store voltage records until it can upload the data.

Voltage Sensing Capabilities

The Low Voltage Disconnect function shuts off access to the battery if the voltage level falls below a defined threshold. The Ignition Sense function shuts off power to connected devices when the vehicle ignition is turned off.

Sequential Boot Up

With the SD-PMU, you could determine which port receives power first upon boot up. This is useful for deployments where the operation of the second device is dependent on that of the first. Use the IoT Cloud to remotely determine the boot up sequence.
