A 24V & two 12V powered USB PCI expansion card communication






USB allows peripheral devices to exchange data with a PC and also to receive power over the USB bus. Unfortunately, the bus supplied power is limit to 2.5 Watts (0.5A @ +5V) per port, sufficient to provide enough power to input devices, web cameras among other low power devices. Other devices like printer, displays, pin pads, external CD-ROM and hard drives still require an external power supply. Here comes Powered USB, it eliminates the need for additional power supplies. Powered USB provides the necessary power as well as the communication signals over a hot plugable cable. In addition, the Powered USB solves the physical host side cable locking problem associated with the standard USB connector by providing a host cable locking mechanism.

The Powered USB PCI Add-On card provides a convenient and affordable way to add up to three Powered USB 2.0 ports to a PC. Devices which require more power than provided by the regular USB interface can be easily installed and used with no need for an additional power supply. SUNIX PUB1200PL Powered USB PCI Add-On card, carrying the latest power switching technology provides +12 and +24 VDC, through the PC power supply directly to its 3 Powered USB ports. Powered USB PCI Add-On card is backward compatible to regular USB 1.1 and USB 2.0 devices.

POS systems become more and more stylish now days, with limited space for the terminal and all peripherals inside. Safe your valuable space and get rid of the peripherals’ power supplies using the Powered USB PCI Add-On card. This Add-On card is the ideal solution for today’s point of service systems, especially allowing the board to be installed in any slim size PC-based system with low profile bracket structure.
