Users can monitor voltage, current, and frequency, which aids in identifying inefficiencies in power usage.

Tip: Implementing remote monitoring can significantly reduce response times to power-related issues. This proactive approach helps maintain uptime and ensures that equipment operates within safe parameters.

Load Monitoring

Load monitoring is a critical feature that provides insights into energy consumption. Modern PDUs offer detailed tracking of voltage, current, and frequency, allowing users to make informed energy management decisions. This capability enables real-time tracking of energy consumption, which aids in better capacity planning to avoid overloading.

• Load monitoring helps identify inefficiencies in power usage.
• It optimizes energy management decisions.
• Proactive management of power distribution helps detect potential issues before they escalate.
• Monitoring occurs at the PDU’s branch circuits, ensuring uptime by detecting overloads or shorts related to connected devices.

The current industry standard for load monitoring accuracy in Basic PDUs is around 1 percent, known as ‘billing-grade’ accuracy. This level of precision reflects clients’ desire to pay only for the power they actually use, a shift from the previous standard of 5 percent.

Alerts and Notifications

Alerts and notifications are vital for maintaining system integrity. A Basic PDU equipped with this feature can send alerts via email or SMS when specific thresholds are exceeded. Users can set parameters for voltage, current, and temperature, ensuring they receive timely notifications about potential issues.
