3020-CM-2050

Product Description

The 3020-CM-2050 is a PowerLogic Circuit monitor by Square D (Schneider Electric.) The 3020-CM-2050 is a data acquisition and control device with digital instrumentation and multiple functions. The 3020-CM-2050's six digit LED display allows the user to access 50 metered values and considerable minimum and maximum data.

The 3020-CM-2050 has the following features:

• Accepts standard Current Transformer (CT) and Potential Transformer (PT) inputs

• Certified ANSI C12.16 revenue accuracy

• True RMS metering to the 31st harmonic

• Power quality readings of THD, K-factor, crest factor

• Real-time harmonic angles and magnitudes.

The 3020-CM-2050 has an instrumentation accuracy of 1%, plus or minus. The 3020-CM-2050 keeps real-time readings in its nonvolatile memory. It is important to note the 3020-CM-2050, unlike other PowerLogic circuit monitors in the 2000 series, does not have expandable memory. Also, the 3020-CM-2050 provides no nonvolatile logging memory.
