ETC Products with Isolated 0-10Vdc Components

In lighting situations that calls for both high-voltage power and low-voltage control wiring, it is important to isolate these runs and avoid high-voltage leakage onto low-voltage lines. While it is not a failsafe or a first line of defense, and you should always meter 0-10Vdc lines to verify 0Vac, ETC has produced several products over time with built-in isolation for the 0-10v components in an attempt to protect the equipment from small leakage levels.   For further details refer to  AC Voltage on 0-10v Lines article.

Additionally, ETC has revised some existing boards to include isolation for small leakage levels, using a new part number for the revised boards.


Isolating control electronics from ground does NOT protect personnel from potential harm from high voltage current on 0-10Vdc wiring.

These products are intended for use with 0-10Vdc drivers that are fully isolated. Damage caused by non-isolated drivers is the responsibility of the installing contractor and is not covered by the ETC warranty of these products.
