How to Select a Switching Power Supply Accurately1.
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.
