October 21, 2016 -- Magnum Energy Solutions introduced a product to the Magnum OPUS line of wireless lighting controls with their metering relay, called the Mx-USR-LM. This relay is an enhancement to their single channel, 0-10V high voltage relay pack and now includes both metering and temperature sensing capabilities. The metering chip utilized can be used to monitor and meter an entire circuit at 120 or 277 or utilized on a per-fixture basis.
When paired with a sensor, such as Magnum’s Mx-ML2, this lighting relay can provide occupancy-based on/off as well as daylight harvesting functionality. The relay can also be paired with a wireless, battery-free light switch for localized control as well as dimming.
The thermistor, which can be modified to accommodate different lengths, can be used to monitor the temperature of the fixture, ceiling temperature, and/or the temperature data from surrounding equipment. This data could be used to more efficiently trigger airflow or fans inside of a manufacturing facility or warehouse, for instance.
The metering and temperature sensing data can be visualized and utilized in a variety of ways. If a building automation platform exists, Magnum’s Mx-EBOX can convert the relay data to BACnet IP objects and then bi-directionally control with the system’s logic. If no building automation platform exists, the data can be delivered through Magnum’s new Mx-CBOX to an Amazon IoT platform for visualization and analytics.
For building level metering, Magnum also offers a meter, which measures electric AC power up to 12 circuits and has a built-in web server and a solid-state memory to retain up to 30 years of data. This Magnum meter supports a wide range of current transformers that can accommodate virtually any size load. This meter is also BACnet-compatible and like all of Magnum’s products, is made in the USA.
