Buy switching power supply should pay attention to what
Consider the use of the field of switching power supply, of course, first of all pay attention to the output current, voltage, frequency, there are several output, the output voltage range, the use of environmental humidity ah, and the size of the power supply size and other technical requirements, you need to switch Power, you can go to Wuhan Crystal Kai source Technology Co., Ltd., this company is specialized in the production of switching power supply, good quality.
1, input voltage, such as 220vac
2, the output voltage, the output current; for example, 24vdc, 6A; -5Vdc, 1A
Their own parameters, the normal voltage accuracy, ripple, input range, current regulation, voltage regulation, insulation and so on. You can also consult the switch tube frequency, appearance, warranty time
