Power over HDBaseT (PoH) power-delivery technology has been developed to facilitate the powering of devices such as televisions and monitors up to 100 watts. The ability to provide power and signal to the device allows for simpler installations.
With increasing power levels, the heat generated within the cable increases as well. This is especially true when the cables are bundled together which is typical in the installation. It is a safety concern when cables are operated above their temperature rating under these conditions. In addition, it is well known that higher copper wire temperatures increase cable insertion loss that can adversely affect cable performance.
With a view to address this concern, UL has worked with HDBaseT Alliance to develop a certification program for Power over HDBaseT cables.
In addition to the PoH cable certification program, UL has also recently been approved by the HDBaseT Alliance as a Recognized Testing Facility for their Recommended Cables program. Under this program, cables are tested in accordance with HDBaseT compliance test specifications to make sure they can effectively transport HDBaseT protocols.
To submit cables for the HDBaseT’s Recommended Cables Program or Power over HDBaseT Cable certification or for additional information, please contact Anthony.T.Tassone@ul.com.
