Introduction to Advance Advance Xitanium SR bridge Xitanium SR bridge The Advance Xitanium SR bridge is designed to connect existing or new 0-10V dimming indoor lighting systems to SR (wireless) connected systems. Applications include offices, public buildings, industrial applications and retail environments.
Features of Xitanium SR bridge Wide mains input range The Advance Xitanium SR bridge can operate on a wide range of mains input voltages from 120Vac – 347Vac. Switchable output using zero crossing detection The output of the Xitanium SR bridge can be switched on/off via integrated relay switching with advanced zero crossing technology.
Xitanium SR Bridge Design-in Guide Sensor Ready (SR) Interface Sensor ready (SR) interface Sensor ready interface The Advance Xitanium LED SR bridge features a digital SR interface to enable direct connection to any suitable SR-certified RF sensor. The simple two-wire SR interface supports these key functions: •...
Control device(s) • Most control devices intended to be used in an SR system will be powered from the SR bus. • When communication is present on the SR bus, the bus gets pulled down by the data packages. This reduces the average current available for the power consuming control device.
Xitanium SR Bridge Design-in Guide Sensor Ready (SR) Interface Is it allowed to add an SR bridge with switched OFF SR supply to this SR system? • Yes, an SR driver with switched OFF SR supply extracts 2 mA from the SR bus. •...
SR bridge use cases Basic SR bridge use case The basic use case for the SR bridge is to connect one or more 0-10V dimming drivers and an SR-certified device to the SR bridge as shown in Figure 7. Figure 7. Basic Xitanium SR bridge use case. By default, the SR bridge dimming curve is set to linear and the range is 1 –...
Xitanium SR Bridge Design-in Guide SR Bridge Use Cases 347V SR bridge use case The SR bridge can handle up to 347V mains input. For basic 347V operation the wiring diagram is similar as for 120/277V operation. Figure 8 shows how a SR bridge can be connected to a 347V 0-10V LED driver and an SR sensor.
For example if (10) 50W drivers are connected a SR Bridge each with a max input power of 50W for a DALI Arc Power command of 254 (full output) then to be able to detect the failure of (1) driver/LED load, the threshold would be set at (9x50=) 450W. The SR Bridge would report/set DALI Lamp Failure when the power measured by the SR Bridge becomes less than 450W.
Xitanium SR Bridge Design-in Guide SR Bridge Use Cases Figure 10. Small Class room retrofitted with SR Bridge solution. SR bridge hallway use case Hallways/long corridors are another area that can easily be retrofitted with SR Bridge and SR sensor to achieve maximum energy efficiency/savings and to create a connected lighting system.
Mechanical design-in Form factors The Advance Xitanium SR bridge is available in two different versions: model SRB-LD is for mounting inside luminaires (see Figure 13) and model SRB-BS includes studs to easily mount the SR bridge onto a mounting plate of a downlight fixture (see Figure 14).
It is mandatory to keep the SR bridge Tc max within specification to meet SR bridge lifetime and failure rate specifications. Please refer to the product datasheet for specific values. Advance Xitanium SR bridges are designed to provide a lifetime of up to 50,000 hours at the specified Tc max.
SR bridge. Surge protection The Advance Xitanium SR bridge has limited built-in surge protection (in accordance with IEEE/ANSIC62.41.2 Transient Surge Requirements). The datasheet gives the protection level of the SR bridge. A specification of 2.5kV means that the SR bridge is tested to withstand 2.5kV line transient for 100kHz Ring wave with 30 Ohms source impedance.
Isolation is also provided between all the electronic circuits and the chassis. Xitanium bridges meet UL 916, and the output terminals have been qualified as Class 2 circuit with UL1310 safety standards. All of the wires in the Advance Xitanium SR bridges meet the UL1452 safety standards.
