ANSI E1.3 The video is a brief introduction into the third of ESTA’s American National Standards, now in its fourth edition. Zero to ten-volt analog control is an old method, but it's still used, and this standard helps define the controller-current-source method used in the entertainment industry as distinct from the controller-current-sink method used with dimming fluorescent ballasts. The video outlines the what the standard covers: transmitter specifications, receiver specifications, cabling, connectors, and marking. It also tells the viewer where to get the standard and the companion document, the Application Guide for ANSI E1.3, for free courtesy of ProSight Specialty Insurance.
