Submetering provides facility managers real-time and historic data on power use and power quality on multiple subsystems in a building’s infrastructure, including interior lighting circuits, exterior lighting circuits, HVAC systems, and any number of other isolated circuits. This can lead to a litany of benefits, including:

•  Reduced Energy Costs
•  Energy Use Planning for Time of Use Billing
•  Tenant Energy Use Billing
•  Cost Recovery/Allocation
•  Multi-Site Rate Negotiation with Your Utility
•  Performance Monitoring
•  Government Regulation Compliance
•  Power Integration with Building Management Systems

The CS-400 system is based on a modular design. As noted previously, there are two primary components: the Submeter and the Hub. The Submeters are UL Listed® so that they may be field installed into a new or existing electrical panel. The Submeters include 14-gauge sensing wires and can be connected to circuit breakers and CT-Coils in the panel. With the voltage sync capability, a minimum amount of wiring connections is needed. This reduces installation cost and complexity and increases system safety.

The Hubs are designed to be mounted outside the panels, with a connection to the Submeter module done with low voltage Cat5 or Cat6 cabling. This adds to the ease and safety of the installation.

Optionally, our EMC software can be installed on an enterprise-level server for managing larger installations.

The modular design of the CS-400 series makes scaling the system simple and cost effective. Each Submetering Hub supports up to eight Submeters, whether the meters are in a single large panel or in separate panels.

To put this in perspective, to be Title 24 compliant a 50,000 square building could use as few as 3 meters to isolate and meter lighting, receptacles, and HVAC systems. Of course, a facility manager could elect to put in more meters to gather power usage of more systems, or to gather information by floor or department. The key here is both scalability and flexibility. Our Submetering system fully supports both needs.

Voltage-Sync – A Unique Cost-Saver:  One of our unique features is the use of voltage-syncing the submeters. This approach reduces the cost and complexity of installing submeters by as much as 87%. Only a single submeter needs to be connected to a metered panel to gather the panel’s voltage data. That base data is communicated through the Submeter Hub to the other meters in the system, reducing the material and labor that otherwise would be required to connect all of the meters to that panel. A true cost savings!
