SD-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:

3 Devices in 1

SD-PMU low voltage disconnect dc-dc converter distribution panel

The SD-PMU can reduce setup costs, operational complexity, and maintenance expenses by performing the functions of three devices: a low-voltage disconnect monitor, a DC-DC converter, and a DC distribution

panel. Rather than installing three enclosures and connecting them through cables, installation now simply involves connecting the batteries and an Ethernet connection to the SD-PMU.

Vehicle Deployments

SD-PMU deployments

Connect the SD-PMU to your car battery to deliver reliable 52V power. Connect the LAN port to your router in order to remotely monitor battery output via the IoT Cloud.

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.
