To determine when, where, and how much electricity is being used to help reduce unnecessary power consumption, a smart multi-circuit monitor is required. Additionally, features such as sub-metering, temperature monitoring, remote control, and harmonic measurement for all electrical branches in the data center are essential. Measuring power across multiple circuits typically requires expensive and hard-to-install power sensors. The challenge in this project is the high metering density within the PDU, and the data center’s main feeders do not allow scheduled downtime for CT installation.

Our PMC-592 multi-circuit monitor was proposed as the solution. Each PDU is equipped with a PMC-592 and four CT sockets, allowing up to 84 low-rated circuits to be monitored. For the main feeders in all data centers, high-rated split-core CTs were used to avoid the need for planned downtime during installation. The PMC-592 supports wiring configurations for both physical branch circuits and virtual meters (vMeters). It comes standard with harmonic measurement on all circuits, two digital inputs for status monitoring, two relay outputs for control, and two RTD inputs for temperature measurement.

The client was pleased with this cost-effective solution, as it addressed all their needs in one comprehensive system. The PMC-592 provided an efficient, scalable, and flexible approach for high-density power monitoring, eliminating the need for complicated and costly installation processes while ensuring seamless integration with existing infrastructure.
