Particle Counters and PoE Series (Part 2 of 3)

PoE Operation
A PSE will not distribute power until it determines if a connected device needs power. This electronic handshaking between the PSE and PD occurs in three stages: Detection, Classification, and Under-Voltage Lockout (UVLO). Download the paper to read the full sequence.




This technology allows the PSE to characterize the power requirements of each PD and manage the power distribution.
Note: A PSE does not force power to a PD; the PSE will only deliver power if the PD requires it.
