Centralized power management PMU701 handles the specific power requirements of the sensors, making sure that each sensor receives steady and suitable power at all times. PMU701 is also responsible for charging the internal backup battery inside the RWS200 enclosure. If an external DC power supply is used with the road weather station, the power is routed through PMU701. In total, PMU701 provides 1 external DC input, 2 solar panel inputs, 4 inputs for analog sensor communications, and 14 inputs for serial communication, 8 of which can be Ethernet-based communication. Surge protection All sensor communication lines and DC power lines route through PMU701 to provide surge protection between the station, the DC power supply, and the individual sensors attached to the weather station. As the RWS200 weather station enclosure is typically mounted to a pole or a metal lattice mast, lightning strikes are a real danger for the weather station. Proper power protection ensures that power disruptions are kept to a minimum, which increases the overall reliability of the system. Power control Continuous and steady power is a luxury for a roadside station. Power Management Unit PMU701 meets the challenges posed by power interruptions and surges caused by, for example, lightning. PMU701 provides surge protection and power to the sensors, including heating power when needed. Intelligent battery management PMU701 automatically detects if the backup battery is faulty, missing, or disconnected and reports it. PMU701 stops charging when the battery is faulty, the ambient temperature inside the enclosure exceeds the battery operating temperature, or PMU701 self-diagnostics detect an internal failure. Simplified configuration PMU701 is designed for simplified configuration and wiring during initial setup or when adding new sensors. Grounding each sensor cable shield is simple and easy, and a quick reference card is provided to ensure that each sensor is connected correctly; once again, to add system reliability. Simplified maintenance PMU701 has the ability to control and cycle the power of each sensor remotely, making it possible to perform some technical services remotely, such as powering down and restarting individual sensors.
