ETC TR20SAF Dual 20A ThruPower Module 350µS with advanced features
Sensor3 all-in-one ThruPower modules allow free mixing of dimming, switching, or manual bypass on a circuit by circuit basis without replacing the hardware in your Sensor power system. A local override completely bypasses the control system to guarantee that the unsuspecting board operator does not dim your intelligent lighting source. In bypass mode, the integral relay will eliminate the choke and SSR power cube thereby providing clean power to critical power supplies and lighting devices.
The ThruPower module supports circuit-specific setup and load feedback that can be accessed remotely with any ACN control system.
Applications
- Where load type is not likely to be known at time of installation
- Where production environment load types are likely to change frequently
- Where your moving lights, LED, scroller, or power supplies warranty depends on constant power
- Low voltage lighting
- Use with quartz, neon, tungsten, cold cathode lighting
- 2-Wire fluorescent ballasts
Attributes
- Mechanically latching relays
- On/off relay activation through the control system
- Manual ThruPower override provides foolproof full AC voltage through from the breaker to the fixture
- Voltage, current, and temperature sensors in all operation modes
- Hydraulic-magnetic circuit breakers with fuse backup
- ThruPower modules are dual density
- Dual back-to-back SCRs for each circuit
- 350μS Risetime toroidal filters
- High-density modular assembly
- Die-cast aluminum chassis
General
- Rated for continuous duty at 100% of rated load
- 2.4kW
- UL and cUL approved
Physical
- Fully magnetic to eliminate nuisance tripping
- 20x Inrush current rating
- 125%, 10-120 Seconds, must-trip rating
- Rated for 100% switching duty applications
Ratings
- 100,000A Short Circuit Current Rating (SCCR)
- Modules withstand hot-patching of cold loads up to full rating
Power Device
- Sealed, patented assembly
- Field replaceable with screwdriver
- Two back-to-back SCRs per circuit
- One control LED and one output LED per circuit
- Mechanical held air gap relay
- Local "on" switch: complete bypass of dimming and relay control
- Integral bonded heat sink
- Integral temperature sensor
- Built-in voltage and current sensors
Filtering
- High quality toroidal filters: 350 μS risetime
- Risetime measured at full load, at worst case firing angle (90 degrees), from
- 10-90% of output wave form
Dimmer Range
- Incandescent, low voltage dimming range 100-0%
- Dimming range of 2 and 4-wire fluorescent ballast is dependent on lamp ballast combination
- Sizing of Neon transformer used in dimming applications should be 1.5x greater than size used in non-dimming application
Advance Features
- Load dropped below recorded value
- Load increased over recorded value
- DC on dimmer output
- SCR failed on/off
- Circuit breaker tripped
- Dimmer module removed
- Dimmer load absent
