Crestron® GLS‑EM‑CT solid 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
Simply route wiring through the circular window of the solid core transformer before connecting the transformer to a GLS‑EM‑MCU.

 
Key Features
  • Provides detailed branch circuit data to a GLS‑EM‑MCU Crestron Green Light® power meter control unit
  • +/- 1% measuring accuracy at 10% to 130% of rated current
  • Twisted pair wire leads
  • Easy wire routing through circular window
  1. To prevent wire noise, the maximum distance between a GLS-EM-MCU or GLS-EM-CTI and a GLS-EM-CT should not exceed 50 ft (15.24 m). This maximum distance applies to the following product models: GLS-EM-MCU, GLS-EM-CTI-* and GLS-EM-CT-*.
