Powering Options
Remote Powering via USB-C Ports
The UCX series devives are designed to provide power delivery for the connected device over the USB-C
connectors.
The following operation modes are available:
▪
Charge one device on the chosen port with up to 60W. The other port can supply up to 5V/3A.
Supported power profiles: 5V/3A, 9V/3A, 12V/3A,, 15V/3A, 20V/3A
▪
Charge one device with 30W (in this case , the other USB-C port can supply 30W or 5V/3A)
Supported power profiles: 5V/3A, 9V/3A, 15V/2A, 20V/1,5A
INFO:
Selecting the appropriate power profile happens automatically, no manual intervention required.
Remote Powering via USB-A Ports (D1-D4)
5V output power capability can be turned on and off for all ports. All ports are able to supply 1000mA.

Power Delivery
With Power delivery, these issues were solved:
#new
▪
Allows negotiation of
up to 60 W
of power delivery to supply or
charge equipment connected to a USB-C port.
▪
Power direction is
not fixed.
▪
Intelligent and flexible system-level
management of power
(negotiation); the two connected partners
exchange real-time PD protocol messages through the CC (control channel) lines.
USB PD supersedes all the previous technologies and does not incorporate them. It can achieve any of the
previous levels, but does so with its own methods.
Power Pins of USB-C Connector
▪
The VBUS and GND pins are power and the return paths for the signals
▪
The CC channel is used for power negotiation
▪
The other CC pin can be used for VCONN powering
USB Chargers
USB-C PD covers a range of different power levels, with different amperage and voltage combinations that
a charger can deliver, depending on what the device asks for and the cable negotiates. These values are
defined by PDO (Power Data Objects).
According to the specification, 12V is not a mandatory Voltage level. The reason for supporting in case of
certain chargers is that the 12V value was on the mandatory list of a former specification.
