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:
The vast majority of automobiles, trucks, boats, and yachts typically make use of a 12- or 24-volt power system. Even though the battery is designated to operate at a specific volt, the actual voltage is fluctuating depending on its lifespan, loading, and state-of-charge.
Pepxim’s PowerFusionTM technology allows vehicle and vessel power systems to achieve uninterruptible, reliable, and stable electrical power supplies. Using our voltage regulation circuit, you can aggregate multiple DC power sources with a wide voltage range from 12 to 56 volts, and transfer to a constant voltage power supply.
Our PowerFusionTM system maintains the safety of your portable power system by monitoring the voltage, converting the fluctuating voltage into an optimum value, and protecting your devices from overvoltage. Depending on model, Pepxim’s Power Management Units can output designated voltage values according to usages. For instance, sensitive onboard telemetry, surveillance cameras, and Power over Ethernet appliances.
3 Devices in 1
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.
This results in significantly reduced network complexity, smaller footprint, and greater network resilience.
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.
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 . With 52V power delivery, the SD-PMU can support switches with 802.3at PoE output.
PEPXIM IoT Cloud
The Pepxim IoT cloud provides a number of tools for remote troubleshooting. On the network level, the dashboard displays the connectivity status and power usage of all your devices on a single screen. On the individual device level, the Pepxim IoT cloud stores comprehensive information on the voltage, wattage, and current of each port, as well as device temperature. This view contains historical data from months ago, making troubleshooting significantly easier. The real-time monitor updates every 5 seconds, enabling instant feedback on any network changes.
The Pepxim IoT Cloud enables you to perform configuration that would otherwise require a trip onsite. From any web browser, you can set voltage, current, and temperature thresholds. If a threshold is reached, the port or device will shutdown. In addition, the IoT cloud also enables you to configure and schedule firmware updates for your Pepxim devices. You can make these configurations upon multiple devices simultaneously, saving significant time.
