ETC ES750 Dimmer UL without Connectors

Using ETC’s Electronic Silent* (ES) technology and a convection cooled design, this 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 now reside alongside LEDs and moving lights, allowing system designs to focus on switched power and data distribution instead of centralized dimming systems.

FEATURES

• ES Dimming technology
  • Produces no lamp noise (exceeds all risetime specs)
  • Electronics sound-pressure level less than 0dBA at 1meter
  • Convection-cooled
• ANSI E1.20 RDM and ANSI E1.11 DMX512A
• Yoke-mount and pipe-mount brackets included, direct mounting on a fixture yoke or to a pipe in multiple orientations to accommodate maximum flexibility (C-Clamps sold separately)
• Local operation
  • One-press dim to FULL for easy focusing (press again to release to DMX input)
  • Up and down level control
  • Returns to previous level after power loss
