The Crestron® GLS‑EM‑CT is a current transformer designed for use with a GLS‑EM‑MCU Crestron Green Light® Power Meter Control Unit. Current transformers are vital to metering power. Crestron offers various split-core models, solid-core models, and high accuracy equivalents for all models.
Crestron® GLS‑EM‑CT split core current transformers are designed for use with a GLS‑EM‑MCU Crestron Green Light® Power Meter Control Unit1 and are essential for reporting branch circuit data to the unit.
Wire Leads
GLS‑EM‑CT transformers are furnished with a twisted pair of wires that connect to a GLS‑EM‑MCU Power Meter Control unit. The wire leads can be trimmed and stripped for specific applications.
Easy Installation
Split core transformers are placed around existing wire feeds by detaching and reattaching the transformer's removable clamp and wiring the leads to a GLS‑EM‑MCU. This method allows for minimal disturbance of existing installations.
