Sensor3 is the foundation for a versatile power system that builds on our proven Sensor™ workhorse system with CEM3 control. ETC's Sensor3 Power Control Systems are the performance standard for top theaters, TV studios, and concert halls worldwide. Because a complete range of Sensor3 racks are available, smaller venues like schools and community theaters can also afford Sensor3 excellence.
Modularity means configurability: mix and match the modules in the racks according to your particular fixture inventory. Now with Sensor3’s new three-in-one ThruPower modules, you can freely jump from Dimmable to Non-Dim, as well as lock a circuit to a constant hot output override without changing modules. The compact design lets you slide up to 48 modules for up to 96 circuits of 1.3kW, 2.3kW, 3.0kW, 5kW and 10kW dimming in and out of a single Sensor3 rack – without tools!
With CEM3 Power Control, your system is high performance, fast to set up and easy to use! Quickly override levels with console-style number-pad entry. Take remote management even further with Advanced Feature (AF) monitoring by providing circuit-specific information, such as load changes, lamp failures or breaker trips directly to the control console.
Our philosophy at ETC is “zero downtime!” Add the optional backup stations for an easy, ‘off the network’ control backup solution for failure proofing. Additionally, system backup is stored directly in the rack – which means no setup during controller changes – and options are available for secondary USB backups.
GENERAL
• Racks available in four sizes
- ESR3-48 48 modules, 96 dimmers maximum
- ESR3-36 36 modules, 72 dimmers maximum
- ESR3-24 24 modules, 48 dimmers maximum
- ESR3-12 12 modules, 24 dimmers maximum
• Dual density (two dimmers per module) and single density
dimmer modules available
• Operating temperature: 0-40°C
- Dimmer room HVAC systems must at all times maintain
the specified ambient temperature at the dimmer rack.
Dimming systems operating within 5° C of the upper or
lower temperature limits must strictly follow installation
and operation guidelines to operate reliably.
