AC220V to DC12V water dispenser accessories refrigeration board circuit board power board water dispenser switch circuit bo

Features:1. board, the same general appearance and shape2. Water dispenser power board with temperature control interface3. It is suitable for replacing the power supply of the cooling chip of the water dispenser4. The power board has a temperature control probe socket (NTC), which can be used alone as a power supply for semiconductor refrigeration chips5. The fan interface is connected to the 12V output voltage in parallel, and the 12V cooling fan can be directly usedProduct s:Input: AC220VOutput voltage: DC 12VProduct size: 122mm*81mm*42mmHole pitch: 110mm*70lluste:For the external temperature probe of the NTC socket, please use the NTC negative temperature thermistor of the model MF52 10K or MF58 10K,When the resistance value of the thermistor is le than 14K (the corresponding temperature is higher than about 15 degrees),Turn on the 12V power supply voltage; when the resistance of the thermistor is greater than (the corresponding temperature is lower than about 10 degrees), turn off the 12V power supply voltage. If you do not need the thermistor to control the temperature, please connect the two pins of the NTC socket with wires Short circuit, otherwise, the 12V voltage is not output.Product List:1x circuit board
