DC- AC INVERTER UNIT CXA-0377 (10W DUAL OUTPUTS WITH DIMMING FUNCTION) Applicable LCD: LQ150X1LGN2A (SHARP) FEATURES: a. This inverter is for two lamps. It has Dimming function(PWM System) and Remote function. b. This product has shutdown function. It prevents from keeping generating the high voltage when the lamps open.(Refer Note.6.) c. With lamp failure detector. Normal Operation Some Lamps Open : CN1-6=0V : CN1-6=5V d. Select the way of dimming (CN1-5) 1. Insert a potentiometer (0-10k) 2. Apply the voltage (0-2.5V) e. The high-voltage area (terminals and patterns) is coated with silicone so as to avoid the defects caused by dust.
