No, Ultra PoE switches are designed for 48V PoE+ or higher.
They do not support or power devices with 12V or 24V inputs
.
Ultra PoE is a higher power standard, so it would deliver excessive voltage to a device needing a lower voltage.
Explanation:
-
PoE (Power over Ethernet) Standards:PoE standards like 802.3af, 802.3at (PoE+), and 802.3bt (Ultra PoE) define the voltage and power delivery for powered devices (PDs).
-
Voltage Negotiation:Standard PoE switches negotiate the voltage and power with the connected device to ensure compatibility.
-
Passive PoE:Ubiquiti uses a 24V passive PoE, which is different from the standard PoE, but also does not support 12V devices, according to HostiFi .
-
Device Compatibility:A device designed to work with 12V or 24V passive PoE cannot be powered by a standard PoE or Ultra PoE switch.
-
Ultra PoE:Ultra PoE standards, like 802.3bt, deliver higher power (60W or 99W) at a higher voltage.
-
Damage:Connecting a 12V or 24V device to an Ultra PoE switch can cause damage due to the excessive voltage.

Can I use a 24V PoE for a 12V camera?
No, you cannot connect a 12V camera to a 24V PoE injector
. The high voltage will damage the device. These passive PoE injectors do not do voltage negotiations, so the PoE device will be affected as you connect it.

What is the maximum voltage for PoE+?
50-57V
Characteristics of PoE+
PoE+ (IEEE 802.3at), also known as PoE plus, is an enhanced version of PoE that provides higher power delivery capabilities. PoE+ switches supply up to 30 watts of power per port, about twice the power supplied by the base PoE standard. The ports have a voltage range of 50-57V .
