The specifications may be changed without any notice.When placing orders,please confirm "Specifications" or "Product Drawing" through TDK sales or distributors.FeaturesThis inverter is for two lamps. It has Dimming function(PWM System) and Remote func tion.This product has shutdown function.It prevents from keeping generating the high voltage when the lamps open.(Refer Note.3-4.)With lamp failure detector.Normal Operation : CN1-8=0VSome Lamps Open : CN1-8=5VSelect the way of dimming (between CN1-6 and CN1-7)1. Insert a potentiometer (0-50kΩ)2. Apply the voltage (0-2.5V)The high-voltage area (terminals and patterns) is coated with silicone so as to avoid the d efects caused by dust.[1] Outline1-1.

Note1-2. For circuit connection, please prefer to test circuit dia gram [3].Note1-3. Please use minimum of 2mm clearance (all directions) between inverter high voltage ar ea and any conductors.Please refer to mechanical drawing for marking of high voltage area.Note1-4. Open voltage (strike voltage) is measured across the transformer secondary winding at no loa d as the reading atthe output connector would be less than the actual value.Note1-5. If the start up voltage falls below Cold Cathode Tube strike voltage, the CCFL will not light up easily special ly atlower ambient temperature. Please review mounting instruction to avoid any abnormal op eration due tocoupling/leakage capacitance of inverter high voltage area to any surrounding conductor.Note1-6. Please check your lamp characteristic for minimum operational current and set the limit point in your design toavoid flickering and/or abnormal operation.Note1-7. For proper operation of circuit protection (fuse or IC PROTECTOR),Please use minimum of 2A capaci ty for inputpower supply.Note1-8. For proper operation: Don't connect the out put VLOW(CN2-4) terminal to the in put GND(CN1-3,4).[2]Absolute maximum ratingsItems Symbols Specification Unit NotesInput VoltageVin 0~15Vrmt -1~Vin+1Vbr 0~16VLoad ResistanceRL//CL100 // 5kΩ // pFOperating Temp. rangeTa-10~70°CStorage Temp. rangeTs-30~85°CHumidity rangeRH95%RHA maximum wet ball temperature is 38°CNo dew.Note2-1.The test circuits added 5pF capacitor across the load resistor for LCD back light stay ca pacitor.TDK CORPORATIONPRODUCT NAME or MODEL,TITLEDC-AC INVERTER CXA-P1212C-WJLNAME OF DRAWINGDRAWING No.PRODUCT DRAWINGCTR-0929-DPAGE4
