- DC Power Distribution PanelsDC Power Distribution Panels Reduce Unnecessary Site Visits And Increase Quality Of Service To Your Customer What if you could do this without physically visiting the site? What if you could do this from the comfort of your office, from your laptop, from your smartphone? Our DC Power distribution panels offer this flexibility.One of the key advantages of wireless broadband – providing high-bandwidth internet access to remote customers – can also present challenges, especially when a remote site experiences a technical issue. This often necessitates a visit to the site by a technician to troubleshoot the problem. In some instances, the issue can be resolved simply by power cycling power to a troublesome device. Ethernet communication options, which allow users to remotely monitor DC power conditions at a site, and if needed, remotely power cycle the connected devices. Our Smart DC Distribution panels also allow you to disconnect non-critical devices in order to preserve battery life in the event of an AC mains failure. All this can be done manually via a desktop PC, laptop or smartphone, or can be preconfigured to occur automatically based on parameters you set. No additional software is required, just a standard web browser. And…
