3. Whether there is a common ground relationship between the electrical ports of each road. If it is a common grounding relationship, there are special requirements for the power supply.
4. During the multi-channel output period, the voltage of the main circuit is determined according to the load characteristics (resistance, capacitance and inductance) and power variation range of each circuit. Generally speaking, the output current is large and the voltage accuracy is high.
5. Identify other indicators such as ripple noise, voltage stability and load stability.
6. According to the temperature, humidity, vibration and other requirements of the actual use environment, the product level with reasonable cost performance is selected.
