Note:
– Requirements for the power supply:
– nominal output of 48VDC (ranging from 47-49VDC)
– the ripple should be less than 200mVpk-pk
– maximum output current should not exceed 3.0A (or limited to 3.0A, because
DICENTIS cables and devices have a maximum rating for this current)
– Advice
– It is strongly advised that the power supply has its own short circuit protection with
a short circuit output current ranging from 4.3 to 5.0A.
– When the power supply has an automatic restart after a short circuit, this restart
function should have an interval time of 3 to 4 seconds and should have no more
than 4 restart attempts.
– Upon powering off the power supply, the output should be less than 9V, 1mA.
– The maximum distance between the (A)PS and the conference device is limited to 100m
due to the Ethernet properties.
