  3. Whether there is a common ground relationship between each power port, if it is a common ground relationship, there are special requirements for the power supply;

  4. In the case of multiple outputs, determine the main circuit voltage according to the load characteristics (resistive, capacitive, inductive) and power variation range of each channel. Generally, the main loop is with large output current and high voltage accuracy;

  5. Clarify other indicators such as ripple noise, voltage stability, load stability, etc.;

  6. According to the temperature, humidity, vibration and other requirements of the actual use environment; select the product level with reasonable cost performance;

  7. If the model specifications in this manual do not meet your requirements, please put forward more detailed technical requirements to meet your actual needs.
