1.7 Supercapacitor (optional)

The ED-IPC2500 supports an optional supercapacitor backup power source, which provides the following functions:

• Power Failure Data Preservation: In the event of sudden power loss to the IPC device, the supercapacitor provides brief power support to critical circuitry within the IPC. Depending on the load, it can maintain operation for approximately one minute under lighter loads or about 30 seconds under heavier loads. This ensures that essential data (such as the device's runtime state, current values of counters/timers, etc.) is preserved, preventing loss due to unexpected power interruption. This is critical for industrial applications requiring rapid process recovery without loss of key information.
• Real-Time Clock (RTC) Sustenance: The device's RTC is crucial for recording event timestamps and sequencing operations. The supercapacitor supplies sufficient power to sustain the RTC circuit after primary power failure, allowing it to continue operating normally for a period.
• Assisting Graceful Shutdown: The supercapacitor supports an orderly shutdown procedure during power loss by supplying energy to the device's control circuits. This enables the system to safely terminate active functions per predefined protocols—e.g., closing communication ports, halting complex calculations, or stopping runtime processes methodically.
