Reliable, Accurate Energy Measurement
As the old adage goes, you can’t manage what you don’t
measure. We’ll go one further: you can’t manage reliably
what you don’t measure accurately.
The Crestron Green Light
®
Power Meter Control Unit
(GLS-EM-MCU) measures both voltage and current at the
incoming electrical service and individual branch circuits to
provide complete and accurate real-time data for use
in assessing power usage and employing energy-saving
strategies. By design, the GLS-EM-MCU integrates with
Fusion EM
™
Energy Management Software to monitor and
manage lighting and other devices throughout a building to
achieve real, meaningful control over energy consumption.
