0-10V Control

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
