To use this feature, a third party NTC thermistor should be connected to the LED power supply as shown in the wiring diagram below. In the end application, care must be taken to place the NTC thermistor close to the hottest spot on the LED module. If LED thermal protection is not required the NTC port on the LED power supply connector can be left open. Vishay, EPCOS, Murata, Panasonic are some of the manufacturers of NTC thermistor. EPCOS part number for reference only B57164K153J (15k @ 25C). Murata part number for reference only - NCP03XH223J05RL (22k @ 25C) Note 3: Graphs for reference. The derating limits can be programmed using the OT Linear Handheld Programmer Derating start = 6.3k; Derating end = 4.3k; Min output level = 10% % Of Output Current 100 80 60 40 20 0 6.5 6 5.5 RNTC in k 5 4.5 4 CONSTANT LUMEN MAINTENANCE The Constant Lumen Maintenance feature of the OTi 48W helps to maintain the required lumen output of the fixture at a constant level throughout its lifetime. In general, LED's lumen output will depreciate over time and in order to maintain sufficient light level towards the end of lifetime, the LEDs are driven at high current initially and will result in more energy consumption. The constant lumen maintenance will give the flexibility to drive the LEDs at optimal driving current throughout its lifetime. This helps in energy savings, constant light output and enhanced reliability of the system. Note 4: A detailed step-by-step instructions are outlined in the OT Programmer User Manual V2.4 ECS288 6/2016 8 END-OF-LIFE INDICATOR The End-of-Life indicator helps the end user to receive a signal from the fixture indicating that it has reached its programmed life-time. After the LED driver reaches the programmed life-time, whenever it is turned ON, it stays at `Dim' level (10%) for 10 minutes and reaches its appropriate level.

UL CONDITIONS OF ACCEPTABILITY (E320395) Conditions of Acceptability - When installed in the end-product, consideration shall be given to the following: * The LED driver was evaluated using an electronic LED load resulting in an output rated current and rated power as indicated in the electrical ratings. * The unit employs a Class B isolation transformer (T1) on the main PWB. The need to repeat the Temperature Test shall be determined in end-use product. Tc point case temperatures in the end-use shall not exceed 90C. * The unit was tested on a 20A branch circuit. If used on a branch circuit greater than this, additional testing may be necessary. * The PWB spacing for use in Damp locations have been evaluated to UL 8750. The unit is completely potted on the bottom and partially potted on the top. Areas that are potted meet spacing requirements are out of Table 7.4 Parts Potted or subsequently coated. Other areas meet applicable requirements in Table 7.4. * The Leakage current test was conducted between the ground terminal, exposed conductive surface and the grounded pole of the supply circuit. * These products are intended for use in Dry and Damp locations. The use in other environmental locations shall be considered in the end product. ECS288 6/2016 9 * For models with rated output voltage above 30V rms (42.4V peak) suitability shall be determined in the cUL end-use application based on accessibility to the user. * These test conditions are for TL rating: This model was tested in a 40C ambient. For Tref. values see Table below. Determination to repeat the temperature test shall be made in end-use product. During the normal temperature test of the end product, the temperature at any point on the case is to be monitored and shall not exceed 90C. When provided, the Tc in a circle can be considered a reference hot spot on the case: Product Tref Max Tref - measured @ 40C OTi 48/120-277/2A0 DIM L * 90C 77C *Applies to DIM or DIM-1 and may be followed by AUX WARRANTY OPTOTRONIC(R) products are covered by our LED Module, OPTOTRONIC Power Supply or Control Warranty.
