CM-2050

About the CM-2050

The PowerLogic CM-2050 is a Circuit Monitor manufactured by Square D/Schneider Electric which allows the user to replace an array of transducers, relays, and meters with one module designed for data acquisition and control. The CM-2050 has a six-digit LED display, giving the user access to 50 metered values. The CM-2050 is a true rms meter able to measure with accuracy highly non-linear loads through the 31st harmonic.

The CM-2050 circuit monitor is manufactured with full instrumentation, a front panel optical communications port, and an RS-485 communications port. The RS-485 port allows for easy integration into existing power monitoring and control systems.

The front panel of the CM-2050 is described below:

The CM-2050 is accurate on volt and current readings to 1% standard deviation. This module keeps real-time readings in non-volatile memory. It is important to note the CM-2050 does not have expandable memory. Also, the CM-2050 has no non-volatile logging memory. UL Listed. 100 to 264 VAC 50/60 Hz. 100 to 300 VDC. 14VA.
