NEMA - ANSI C137.1
Lighting Systems— 0-10V Dimming Interface for LED Drivers, Fluorescent Ballasts, and Controls
|Publication Date:||1 January 2019|
This Standard specifies the 0-10 volt control interface method and performance requirements for dimmable LED drivers, fluorescent ballasts and dimming control units where output power is adjustable between minimum/off and maximum via a control input signal. The interface may be from one or more control units to one or more drivers or ballasts. Note: Dimmable LED drivers, and fluorescent ballasts are hereinafter referred to together as driver/ballast(s).
Applications include, but are not limited to, commercial, residential, industrial, roadway and area, and hospitality. Applicable devices include, but are not limited to, dimmable drivers and ballasts that may be internal or external to luminaires, dimming controls, and daylighting controls.
This Standard does not specify control by pulse-width modulation (PWM).
Note: Compliance with this Standard provides a documented means for manufacturers to specify values that designers and specifiers can use to assess interoperability.
