The PMU-DD-52V-400W 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. This results in significantly reduced network complexity, smaller footprint, and greater network resilience.
Whether enabling free WiFi for buses, or maintaining surveillance on maritime deployments, you need to rely on battery power. Any battery-powered deployments will face challenges such as voltage fluctuation, the inability to troubleshoot, and battery drainage. The PMU-DD-52V-400W can solve these issues. The device 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. It 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. And 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.
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.
