MORNSUN®2. Typical application circuit C1 Note: 1. To further reduce output ripple, a 1uF-10uF capacitor can be connected in parallel to both ends of C2 and C3. 2. The current-limiting resistance can be adjusted to meet the requirements of input impulse current if the input impulse voltage is too high. The circuit between the signal input terminals consists of high-speed opto-coupler LED and 200 Q resistance connected in series. Therefore, the current-limiting resistance can be calculated based on the following formula: VI -1.7V 3. If the application environment is poor, in between 9 feet and...
