Dimming down typically reduces the forward voltage. Ensure the forward voltage of LED modules is always ≥ 35V, even when dimmed down, otherwise the reversible protection is triggered resulting in no output power. 20121218 AA32184 Page 5 of 12 OPTOTRONIC® Technical Information OT DALI 45/220-240/700 LTCS 700mA Constant Current LED Power Supply with DALI and LEDset/DIPswitch Edition: Dec. 2012 subject to change Efficiency [%] Typical Efficiency and Power Factor versus Load 100 1.5 90 1.4 80 1.3 PF 70 1.2 350mA 700mA 60 1.1 50 1.0 40 0.9 30 0.8 20 0.7 10 0.6 0 0.5 15 20 25 30 Output Power [W] 20121218 AA32184 Page 6 of 12 35 40 45 Power Factor 500mA OPTOTRONIC® OT DALI 45/220-240/700 LTCS 700mA Constant Current LED Power Supply with DALI and LEDset/DIPswitch Technical Information Edition: Dec. 2012 subject to change DIPswitch The nominal output current of the constant current LED power supply is set either by the DIPswitch and the LEDset interface: Setting DIP1 DIP2 Iout_nom P max D C B A1) Off On On Off Off On Off On 700mA 350mA 500mA 700mA 45W 42W 45W 45W Vset Open, NTCset open, no digital dimming Iout = 0mA 2) Iout = 350mA Iout = 500mA Iout = 700mA 1) Factory setting 2) LEDset interface unplug protection is enabled Settings A, B, C are intended to set the nominal output current to one of the standard values (350,500,700) and optionally use Vset, NTCset and DALI/TouchDIM to dim down the current. Setting D is intended to use the LEDset interface to define the nominal output current level in the range 50 – 700mA, see the OPTOTRONIC_LEDset_Application_Guide for further details. Settings A and D differ from the protection against accidental LEDset interface disconnection (enabled in D) The maximum output current is controlled by the Vset input voltage as following: Iout_max Iout_nom (Vset-1) / 9 0 mA Iout_nom Iout_nom 0 mA Vset 1V .. 10V 0V .. 1V 10V .. 12V 10V .. 11V 11V .. 12V DIP switches setting A, B, C, D A, B, C, D A, B, C D D LEDset interface LEDset allows to control the output current of the control gear (ref. to LEDset application note). The input voltage of the Vset pin defines the output current relative to the maximum nominal current of the control gear. LEDset interface is not isolated to the secondary side of the LED driver output. +12Vset Vset NTCset GNDset Auxiliary supply 12V +15/-8%, 15mA max.

In those three operation modes the ECG does not switch off as soon as Vset exceeds 11V (no protection region).

The Iout_nom is linearly reduced from 100% down to 50% depending on the NTC resistor values respectively from 6.3kΩ down to 5.0kΩ, with lower values until 4.3kΩ the output current remain at 50% and then it is switched OFF (it turns ON again automatically with values greater than 5.0kΩ). The following table reports some example of typical NTC values (Murata NCP18) and related temperature thresholds (NTC resistor tolerance may affect the threshold).

If the product operates at too high temperature, the output current Iout_nom is reduced by 50%; the protection is reversible.

Earth connection Earth connection is not required but may be used to improve EMI performance of the installation. Wrong wiring This control gear is inherently protected against wrong wiring. The wrong connections between LED+ with Vset, NTCset and GNDset could damage irreversibly the ECG. All the other wrong wirings on the secondary side, once removed, make the ECG work regularly. LED- and GNDset terminals cannot be connected together. Vset should not be applied with a voltage in case the power supply isn’t supplied. General notes Proper and safety usage and installation of the product shall comply to product datasheet, OPTOTRONIC Technical guide, DALI Technical Guide and LEDset application guides.
