DESCRIPTION
The E3x Series Panelboard Monitoring System provides a cost eective solution for
electrical load management, making it ideally suited for applications where loads
are dynamic, such as the data storage industry, lighting panels, etc.
The E3x series monitors the current, voltage, and energy consumption of each
circuit in a panelboard including the main breaker. The accumulated information
can be transmitted through the communications interface. Data updates
occur roughly every two seconds to provide timely preventative maintenance
information. As a circuit approaches the user-congured thresholds, alarm
indicators are triggered, preventing costly downtime from overloaded circuits or
failed loads. (See graph, facing page)
