【Variable power supply with dual LED Display】Our 0~48V power supply adjustable features a dual-knob design, with one knob used to adjust the voltage, ranging from 0~48v, and the other knob used to adjust the current, ranging from 0~12.5A. Whatever voltage or current setting you need, just turn the knob gently. Our LED display screen will clearly and brightly show you the current voltage and current settings, allowing you to grasp all the information at a glance. 【Multi-port Converter with High-efficiency Dustproof】This 48V dc power supply is equipped with three sturdy and durable output ports, each of which has undergone rigorous design and testing. Additionally, dust covers are specially designed above the ports. This innovative design not only effectively prevents dust intrusion but also avoids unnecessary misoperation due to accidental touches. 【Durable Aluminum Case with Intelligent Cooling Design】This AC to DC converter 110V to 48V uses an aluminum housing, which is durable and fashionable. The perforated design not only enhances the appearance but also effectively reduces the temperature of the 48 volt power supply, improving its efficiency. It has a built-in cooling fan with heat dissipation holes and a temperature sensor. When the internal temperature is too high, the fan automatically starts to achieve intelligent cooling. 【High-Quality Internal Components for efficient voltage conversion】In terms of internal components, we have used high-quality oxygen-free coils and transformers, ensuring stable voltage conversion, reducing energy loss, and improving the overall performance of the product. At the same time, the EMI filter capacitors effectively filters out the noise and interference in the power supply, ensuring clean output current. By using advanced chip design, we provide stable and safe voltage support for the connected devices. 【Multiple security features for reliable operation】This adjustable power supply has multiple protection functions, including short-circuit protection, overcurrent protection, overload protection, and overtemperature protection. We also have status indicator lights, and when the indicator light is on, it means the power supply is in normal working condition. If the indicator light starts flashing, it means that the converter has exceeded its designed protection range. At this time, please check the connected device and the power input, and take appropriate measures. 【Versatile Power Converter for Diverse Applications】This versatile transformer is designed for a wide range of devices and scenarios, including LED lights, home security systems, automotive systems, industrial equipment, and more. Featuring a 24V power converter, it seamlessly converts AC to DC, making it the perfect companion for your power needs whether you're at home, in your car, or anywhere else.
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.
