Application Guide Rev. 1.0 2015.04.01 Application Guide for Samsung LED Drivers Output current can be set by a resistor connected between Rset and Rset. Specifications Unit Connectors type WAGO 250 Series or Compatible - Wire cross-section 0.5 ~ 1.5 mm2 Wire peeling length 7.0 ~ 9.5 mm Table.1 Terminal specification Driver output current setting guide When Rset is not connected, the output current is max current. The output voltage is limited by max output power. The output current setting method. 1. Select the Rset value. (Refer each driver`s specification) 2. Connect the Rset resistor to terminal. Fig.1 Output Characteristics (50W driver) If you’ll use the dip type resistor, we recommend preformed leads resistor as shown in Fig. 3 To reduce the tolerance of output current, Rset higher than E48 grade are recommended. (ex. E48, E96, E192) Please refer to setting guide as shown in Fig. 4. picture and setting video. Fig.2 Driver connection & wiring Fig.3 Preformed lead Resistor Fig.4 Rset setting picture Rset Setting Guide Step 1. Please prepare the preformed vertical resistor so that you can put the two leads into the driver’s Rset holes more easily. ※ Refer Rset value in each driver’s specification for current setting. Step 2. Picture of Driver connection and wiring: Make sure you are putting the resistor into the holes of Rset. Step 3. Push the button right before Rset holes using flat tip screwdriver. It will make the holes open, and put the preformed resistor into the holes. Release the button to tighten the holes Step 4. Pull a little bit the resistor to make sure it tightly captured inside.
