Detection stage Voltage
Classification is
Class 0
, 0.44 to 12.94 Watts. In fact
after conversion losses and normal
drive.web
device power consumption of ~3.2 Watts,
~6.5
Watts is available for 24VDC loads.
Maintain Power Signature is always present once the
PoE circuit is validated. Approximately 16 mA @
48VDC is drawn from the PSE even when your
