Analog Control Topology with low voltage wiring
IEC standard (IEC 60929) for the general lighting
From ANSI C82.11 for 0-10v
ANSI standard E1.3 (PLASA/ESTA) for theatrical lighting
Not for dimmable fluorescent ballasts
Protocol works by varying the voltage over the two control wires from 0 volts to 10 volts
A separate Switched Hot and Neutral wire are required to turn the ballasts on and off
Depending on the manufacturer of ballast and control, the control wires may need to be run separately from the line
voltage wires (hot and neutral)
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
IEC 60929 for General Lighting
What it defines:
The ballast/driver sources the current for the 10 Volts
The control sinks the current
At 10 Volts or above, the lights go to full
At 1 Volt or below, the lights go to their minimum level
It does not define dimming performance, power performance, lifetime, etc.
ex: 1% and 20% low end drivers can all follow the standard
ESTA E1.3 for theatrical lighting
What it defines:
The control sources the current for the voltage
The load sinks the current
10V is 100% light
0V is off
Confusion results from 0-10V LED fixtures that are developed for the theatrical market and are moving into general lighting.
What it can do:
Retrofit- control wires do not have to run in the conduit (in some code jurisdictions)
Dimmed zones can be independent of line voltage wiring (in some scenarios)
Ballasts can be dimmed independent of existing circuiting (but not switched)
Single 0-10V Sensors can be connected directly to ballasts
