In satellite ground stations the bias current for LNBs has to be provided by special power supplies monitoring also the current supplied to the LNBs.
DEV offers a series of LNB Powering solutions for various application needs.
Frequently, these power supplies are required to monitor the current supplied to the LNBs. And usually, almost no space is left for these power supplies in the racks on site.
DEV Systemtechnik has developed a series of L-Band multi channel bias tees for the professional use which cover all these requirements. There are available 1 RU devices (the DEV 8122 and the DEV 8123, both products are available with two or with four channels) and the DEV 8120 as a 3 RU device. The DEV 8120 is intended for larger applications and provides convenient channel monitoring and bias current monitoring capabilities. The 3 RU chassis of the DEV 8120 can be equipped with up to 27 dual channel bias tees.
Please note that all our RF over Fiber Tx modules are able to power LNBs.
