Condition is Used. Shipped with UPS Ground. Benefits of Sensor+ SineWavedimming• Lamp filament noise eliminated• Less than 1% harmonic distortion reducespower costs• Unity Power Factor• Minimum 97% efficiency – load dependant• Control over wide variety of loads in a system –resistive, inductive or capacitive• Ability to dim ballasted loads such as HMI fixtures1• No minimum load – perfect dimming curve evenwith very low wattage loads like LED’s• Total short circuit and overload protection withoutbreaker tripping• Extended lamp life due to elimination ofload switching and reduced peak voltage For lighting applications requiring the quietest and mostversatile dimming the entertainment industry offers:Sensor+ SineWave. The newest member of the ETC familyof dimming systems is a different approach to dimming.By controlling the amplitude of the AC sine wave, Sensor+SineWave eliminates filament noise and achievescomplete silence at the lamp. No acoustical interference.Plus, SineWave provides quiet dimming of any load –even ballasted HMI fixtures and low-wattage LEDs. Professional features, exceptional reliability. Sensor+SineWave technology – with Ethernet control,comprehensive status and reporting are all available nowfor installed dimming systems. Sensor+ SineWave racksare engineered with the best of Sensor rack technology –easy to install, simple to use, and inexpensive to service.Sensor+ SineWave racks are shipped fully assembled –no additional assembly required by the contractor.Convenient front access, with readily accessible line, load,neutral and control terminations, makes ETC’s dimmerracks the choice of contractors and installers. Constructedof heavy gauge steel and extruded aluminum, withcomponents designed to a precise fit, these racks areSensor-rugged, reliable and low maintenance. Sensor+ SineWave Racks• 24-module rack configuration• Front-access installation with easily accessible line,load, neutral and control terminations• Single or bussed power feeds (Busses to standardSensor racks)• Rated for 100,000 AIC with listed modules• Direct Ethernet control signal input as well as two DMXinputs (ETCNet2 native device) – (ACN when available)• Includes Advanced Features (AF) Sensor SineWave DimmerModulesThe SineWave Dimmer Module provides effective andquiet dimming of any load: resistive, inductive orcapacitive. SineWave dimmers are even able to dimballasted loads such as HMI fixtures and low-wattageloads like LEDs. The design features high-density modularassembly, tool-free insertion and removal, fully magnetic100% rated circuit breakers, and electronic low-end setcontrols via the CEM+ control module.• Two 2.4kW dimmers per module• Complete control of a wide range of loads includingdimmable electronic ballasts, LED’s, motors andconventional incandescent lamps• Voltage, current and temperature sensors ineach dimmer• Fully magnetic circuit breakers• 100% duty cycle at full rating• Electronic low-end set controls via the CEM+• Includes Advanced Features (AF)
