Overview

When designing a remotely operated and controlled power supply IoT device, working with AC power can be an obstacle. Implementing electrical isolation boundary technology allows the usage and monitoring of AC while simultaneously creating DC transformation space. That isolation also enables the on/off gateway and a TRIAC phase dimmer to vary the current. 

Another issue with remote power supply IoT control is the distance between devices and the facilities center. In a smart network, communication among devices — and between devices and the controller — can be done through cellular, Wi-Fi or long-distance radios. 

To ensure product maintenance, it is necessary to monitor the health of the input device along with the monitored system. Sensors and IoT monitoring devices — a term encompassing onboard circuitry that processes data, communicates with onboard sensors and provides connectivity to the onboard wireless devices — report readings, trigger outputs and make reports using a cloud-based network. 

A final design challenge is to guarantee ongoing data collection and communication, even in the event of a power outage. Attaching a rechargeable onboard battery device, capable of running the monitor without the AC power source, covers that need.

This white paper by Sealevel reviews solutions used to make an IoT power supply monitoring and control device. Covering AC monitoring, output voltage control and operational feedback, the paper details techniques that created a dimmable, remotely operated lighting device capable of communicating with other devices in its network and being monitored for preventive maintenance.
