Select the resistor’s value using the following chart or Rset formula. Note for terminals 26 and 27: open circuit Iout = 100 mA; short circuit Iout = 700 mA. Check the LEDset application note for further details and suggestions: www.osram.com\ledset Digital programming: power up the unit and connect the DALI terminals to the DALI magic (USB to DALI interface), use the Tuner4TRONIC® SW (available only for OEMs upon registration on the myOSRAM portal). For further information check: www.osram.com/t4t Typical Iout vs Rset Rset formula and standard Iout values I OUT A 5V 1000 Rset Iout [mA] Iout [mA] nominal actual Rset [kOhm] E48 series 250 255 19.6 350 357 14.0 500 500 10.0 700 700 6.81 6.8 E24 series Refer to the LEDset application note for further details. Configuring the unit’s functionalities All user configurable features of the OTi DALI 35/220-240/700 LT2 L can be adjusted using the Tuner4TRONIC® SW (available only for OEMs upon registration on the myOSRAM portal) and the DALI magic. For further information check: www.osram.com/t4t A subset of user configurable features and all DALI parameters can be configured using the DALI Wizard SW and DALI magic. For further information check: www.osram.com/software. Powering up the unit for programming The unit must be powered up in order to enable the programming through the DALI terminals. To improve the programming operator’s safety, in place of the mains voltage, only for programming purpose, the unit can be powered up using a SELV 48 Vdc power supply, delivering the following performance: Output voltage range: 48Vdc -7/+20 % (44.6 - 57.6 Vdc) Output current: continuous 100 mA; inrush 1.5 A, 2 ms peak Automatic restart from overload or short circuit Suggested SELV power supply: OPTOTRONIC OTe 25/220-240/420 CS (use 420 mA output), with cable clamps accessory. Important notice: OSRAM is not liable for possible wrong programming in case of use of external power supplies not compliant with the above mentioned performance requirements. 3 Edition: 11 Feb. 2015 Ver.: 1.1 Status: Released Misprints and technical changes excepted OPTOTRONIC® LED Power Supply OTi DALI 35/220-240/700 LT2 L Product Data Sheet Performance charts Typical Operating window Dimming operating area Typical Efficiency vs load Rated operating area Typical Power factor vs load Typical THD vs load 4 Edition: 11 Feb. 2015 Ver.: 1.1 Status: Released Misprints and technical changes excepted OPTOTRONIC® LED Power Supply OTi DALI 35/220-240/700 LT2 L Product Data Sheet Remarks All values have to be considered typical and measured (where applicable) in standard condition 25 °C ambient temperature. Input over voltage protection: mains up to 350 Vac, for two hours maximum, will not destroy both the unit and the load; shut down of load might occur in this condition. Output short circuit / undervoltage protection: shut down of load happens if Uout is below 20V (typ. 15V); the unit automatically tries to switch on the load again every 2-3 s for 0.1 s delivering the selected nominal current. Output overload protection: the unit automatically reduces the output current to keep the output power below about 37 W. Output over voltage protection: the unit automatically reduces the output current to keep the output voltage below 54 V; the output current is reduced down to 180 mA typ., then the load is switched OFF. The unit automatically tries to switch on the load again every 2-3 s for 0.1 s delivering up to the selected nominal current. No load operation: the unit automatically tries to switch on the load every 2-3 s for 0.1 s delivering the selected nominal current; despite this operation mode is safe for both unit and load, it is not recommended. Do not put a switch between load and unit. Over temperature protection: the unit is protected against temporary overheating by automatic reduction of the output current when 75°C < tc < 95°C typ., and by automatic power off if 95°C < tc < 100° typ. The protection is self restoring. Touch current: lower than 0.7 mA, according to EN 60598-1 ann. G and EN 61347-1 ann. A Switchover time: lower than 0.5 s, both AC and DC mains. Output power hold time: > 4 ms, in case of mains dips. Emergency lighting: this LED power supply is suitable for emergency lighting fixtures acc. to EN 60598-2-22; EOFI = 1% - 100% according to EN61347-2-13 ann J.
