How to Select a Switching Power Supply Accurately
1.Identify Product Parameters:
First, determine your product's input voltage, output voltage, output current, and rated power.
2.Match Power Appropriately:
If the input voltage is 110V, it is recommended to select a switching power supply with 1.4 times the rated power.
If the input voltage is 220V, it is suggested to choose one with 1.2 times the rated power.
3.Ensure Voltage Matching:
The product's voltage should match the power supply's output voltage, with an allowed voltage fluctuation range of ±5%V to ensure normal operation.
4.Ensure correct wiring:
Please make sure the input and output terminals are connected correctly when wiring.
It is strongly recommended to have a licensed electrician perform the professional installation.
5.Special Application Notes:
For battery-powered products, ensure that the battery terminal is equipped with a constant-current and constant-voltage charging module to protect the power supply and battery.
For motor-driven products, due to their characteristics,it is recommended to choose a switching power supply with 2 times the rated power to ensure stable operation.
