POWER SOURCING EQUIPMENT HAVING AUTO-ZERO CIRCUIT FOR DETERMINING AND CONTROLLING OUTPUT CURRENT

摘要

The present invention provides a novel system and method for controlling the output of the power sourcing equipment (Power Sourcing Equipment) at a power (Power over Ethernet) device via Ethernet based on the hold (threshold) when current limiting thresholds. The PSE has an auto-zero (auto-zero) circuit for comparing the current limit threshold to the monitored output current of the PSE in order to control the output of the PSE. ; PoE, power sourcing equipment (Power Sourcing Equipment), the threshold (threshold), the auto zero (auto-zero) circuit.
