Monitor DC voltage and current into the switch from your batteries. Monitors the DC power supply temperature with auto and programmable thermal shutdown. Program the switch to shut down lower priority POE ports when batteries get low and to restore them when sufficient reserves return or when it detects charging has resumed from solar or wind.If power gets too low it can be configured to shut down all POE ports and hibernate your remote site until it detects solar or wind charging has resumed and sufficient reserves are generated. You can chose to run your batteries all the way down to 9V to keep the tower up or have it shut down in stages to preserve your energy. Since we designed the power supply to have its own micro processor and to communicate to the switch itself we have full control over the power supply and all relative telemetry generated by sensors built into the power supply.
