Crestron Green Light® Power Meter Control Unit Crestron GLS-EM-MCU ® Crestron Green Light Power Meter Control Unit: GLS-EM-MCU Introduction The GLS-EM-MCU is an Ethernet-based power metering control unit, designed to log overall electricity usage in real time. It measures and tracks actual energy consumption by attaching to the incoming electrical service and branch circuits.
Crestron Green Light® Power Meter Control Unit Crestron GLS-EM-MCU 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® offers various split-core models that work with 600, 400, and 200 Amp feeds; these devices clamp around main feeds.
