About the CM-200

Hardware Tips and Specifications

The CM-200 is a circuit monitor in the PowerLogic line manufactured by Square D/Schneider Electric. The CM-200 is designed with full instrumentation to easily integrate into existing power facilities. It is designed to be compatible with other PowerLogic devices. The CM-200 offers waveform capture as a standard feature. The module also has standard RS-485/RS-422 communications, so it is able to communicate with almost all new and existing networks. The CM-200 has true RMS sensing, is Sy/Max compatible, has microprocessor-based controls, is user configurable, and accepts standard CT and PT inputs (5A and 120Vac.)

The CM-200 does not have a local display; all data must be accessed through its communications port. Examples of available data include:

Demand readings of

• Peak Demand of Real Power and Current
• Predicted Demand of Real Power
• Average Demand of Real Power and Current (0 to 9999A or 0 to 999.9A)

Energy readings of

• Accumulated Energy or Accumulated Reactive Energy

Instantaneous readings of

• Current, Apparent rms (0 to 9999 A or 0 to 999.9 A)
• RMS current (0 to 9999 A or 0 to 999.9 A)
• Temperature (-100 to + 100 Celsius)
• Frequency (23.00 to 65 Hz)
• RMS Voltage L-N (0 to 32,767 V)
• RMS Voltage L-L (0 to 32,767 V)
• Power factor
• Real Power, 3-Phase total
• Reactive Power, 3-Phase total
• Apparent Power, 3-Phase total

The CM-200 is self-cooled via convection through its 16-gauge steel construction. No ventilation openings have been provided or are needed. Typical mounting of the CM-200 requires a semi-flush mounting. However, another method may be used where space is limited.
