around the feed wire of each circuit, and then connected to the GLS-EM-CTI current
transformer interfaces. Up to four GLS-EM-CTI can connect to a single
GLS-EM-MCU for monitoring of up to 84 branch circuits.
Current Transformers
Current transformers are vital to metering power. Crestron
models that work with 600, 400, and 200 Amp feeds; these devices clamp around
main feeds. Solid-core models exist for 50 and 20 Amp circuits; the wire must be
routed through the closed loop of the core.
Real-time and Logged Data
Inherent to the GLS-EM-MCU is the ability to provide both real-time and logged
power usage data. Real-time data can be used on touch screens or lobby displays to
show instantaneous usage. The energy usage screen within Fusion EM software
provides attractive charts and graphs that illustrate the facility's energy consumption.
Additionally, logged data can be shared with Fusion EM for more detailed reporting.
The GLS-EM-MCU stores the logged data in non-volatile memory to prevent data
loss.
