ETC 7145A1101-1X overview

  • 1Description

The 750W Distributed Dimming Series ES750 Electronic Silent Dimmer from ETC uses the ES (Electronic Silent) technology and a convection-cooled design. This bare end, high-performance dimmer can be used with any 750W or less tungsten fixture. By taking DMX control signals directly, this self-dimming tungsten fixture can reside alongside LEDs and moving lights, thereby allowing system designs to focus on switched power and data distribution instead of centralized dimming systems.

Note: Sound level pressure falls below minimum audible field (0 to 20 kHz at <3.2' (1.0m) from unit.

Mounting Flexibility

Yoke-mount; universal-mounting bracket included
Direct-mounting on a fixture yoke in multiple orientations to accommodate maximum flexibility

Local Operation

One-press dim to Full for easy focusing (press again to release to DMX input)
