INTRODUCTION
The Crestron Green Light
with a GLS-EM-MCU Crestron Green Light Power Meter Control Unit. The GLS-EM-CTI
current transformer interface, in conjunction with the main control unit, facilitates the
monitoring of multiple branch circuits. This allows users to monitor the power consumption
of a particular area or device. Crestron
around the feed wire of each circuit and then connected to the GLS-EM-CTI current
transformer interfaces. As many as four GLS-EM-CTI units can connect to a single
GLS-EM-MCU power meter control unit for monitoring of up to 84 branch circuits.
