The Basic Knowledge of 0-10V 2019-07-26

0-10V control is becoming popular again with LEDs because it is an open standard that any manufacturer could meet.

0-10v dimming

However, there are two types of 0-10V and in the lighting industry you must follow the IEC standard in order to operate with existing building controls. This standard states that the control sinks current and the driver sources current.

Two control methods: current sink and current source

The IEC standard for general lighting requires:

     Control to be the current sink

The ANSI standard for theatrical lighting requires:

     Control to be the current source

You CANNOT mix controls, ballasts or drivers from these two standards

Meeting the standard will ensure compatibility but not performance
