DALI AMBIENT SENSOR OUTDOOR
DALI Ambient Sensor Outdoor is a sensor of illuminance and correlated colour temperature that uses DALI bus for biasing and the communication. Besides of the sensing features it is also capable of regulation of variously addressed Tunable White luminaires. DALI Ambient Sensor can therefore act as simple sensor, whose data are processed by another device on DALI bus or it can act as control device for automatic control of illuminance and correlated colour temperature. DALI Ambient Sensor Outdoor is suitable for outdoor application (IP 65).
DALI Ambient Sensor senses the light conditions in the area – illuminance in luxes and correlated colour temperature (CCT) in Kelvins. The measurement runs automatically with automatic range switching. The range of measured illuminance is from 100 lx to 30 000 lx. The range of CCT measurement is from 2 500 K to 8 000 K. For the communication the sensor uses DALI protocol typical for lighting installations. The sensor reacts on its address that is possible to set using any standard DALI configuration tool. Other parameters of the sensor can be set only using USB/DALI Bridge and its software tool.
- Biasing from DALI bus, input voltage range iscompatible with DALI standard
- Illuminance and CCT sensing
- Passive / Active mode – offers direct regulation of Tunable White luminaires
- Configuration via DALI bus
- Installation ceiling surfaced
- Voltage at DALI input: 12–25 V DC
- Input current: < 9 mA
DALI Ambient sensor is suitable for installation to the ceiling and for connection to DALI network. The address can be settable by any DALI configurator, the other parameters like timing, final CCT or illuminance level and regulation, regulation mode can be set by DALI / USB Bridge.
By default, the sensor functions in passive mode with regulation disabled and where measured values can only be read. The basic parameters required for regulation are desired illuminance and CCT values and connection to type-defined and controllable Tunable White luminaires. The sensor can be used to regulate warm/cold twochannel luminaires, brightness/ CCT two-channel luminaires and DALI type 8 luminaires. It is possible to assign each channel its own address, for example, a cold channel, warm channel, brightness channel, CCT channel or DALI type 8 channel. All connected TunableWhite luminaires can be controlled in parallel using illuminance only regulation, CCT only regulation or dual regulation.
