|||||||||
Unless otherwise stated, all specifications are based on input voltage of 220VAC, rated load, and ambient temperature of 25°C. Our accuracy measurement takes into account any errors, voltage regulation rate, and load regulation rate. | |||||||||
Accuracy: Our accuracy measurement takes into account any errors, voltage regulation rate, and load regulation rate. |
|||||||||
Ripple test: To test for noise or ripples in the output, we recommend connecting the power supply and load with a 30cm twisted wire and adding 0.1UF and 47UF capacitors at the load end. The output can then be measured using a 20MH oscilloscope at the load end |
|||||||||
Load regulation: Our load regulation measurement is conducted by testing the output across a range of 0% to 100% load change. |

7.Precautions |
|||||||||
*Before using the power supply, first confirm whether the input and output voltage specifications are consistent with the marked value of the power supply used. | |||||||||
*Please check whether the input and output leads are connected correctly before powering on to avoid damaging user equipment or burning out the power supply. | |||||||||
*The component pins on the bottom of the bare board power board are conductive. Do not touch the bottom of the board with your hands during testing. It is necessary to put an insulating rubber pad or something non-conductive on the bottom of the board to avoid electric shock or burning out the power board. |

advantages of power modules
1. Stability: The power module delivers a steady flow of voltage and current, ensuring your electronic equipment operates smoothly and without any risk of damage due to fluctuations in voltage levels.
2. Exceptional Performance: Boasting high efficiency and low voltage drop, this power module offers stable output current and voltage, heightening your equipment's performance and capabilities. With this module in place, you can trust that your devices will operate at their optimum levels at all times.
3. Safety: The power module incorporates a multitude of protective measures, including overload, overvoltage, and overtemperature protection, that ensure the equipment remains intact during operation and the users are safe from any potential hazard.
4. Cost-effectiveness: Implementing power modules facilitates the safeguarding of multiple devices from detrimental conditions such as power surges and voltage fluctuations, which in turn reduces the need for expensive repairs or replacements, making it a practical and cost-effective solution.
5. Convenience is key! With the power module, you can easily install it right into your device without the hassle of extra cables or plugs. This not only saves you valuable space, but it also helps cut down on costs. The power module is an essential component in all electronic equipment, ensuring that everything runs smoothly and reliably. As technology advances, we need smaller, more efficient, and safer power modules that are easy to take on-the-go. These advancements in power module technology allow us to meet the demands of modern equipment and ensure long-lasting, reliable performance.
The difference between power module and power adapter
A power module typically denotes a power supply device that can deliver steady DC power within a specific input range. It boasts superior efficiency, reliable stability, and minimal fluctuations in both input and output voltage. As a result, it finds widespread application in various electronic equipment, including computers, communication devices, medical tools, and much more. With its outstanding features, the power module contributes to the smooth functioning of these gadgets, making our lives easier and more enjoyable.
A power adapter is a handy little device that converts alternating current to direct current to power up low-power electronic devices. It's lightweight, portable, and affordable, making it a popular choice for mobile phones, laptops, and smart homes. The output voltage and current are generally fixed values that are ideal for gadgets with lower power needs and single voltage and current specifications.
To sum up, the power module is a top-level power supply with stable current and voltage, suitable for equipment with high power consumption and high requirements for voltage and current fluctuations. However, power adapters cater more to the power needs of lightweight, low-power devices and are thin, light and portable. Both have their own unique use cases and benefits, making them indispensable tools for a variety of applications.
The difference between power module and switching power supply
Firstly, the power module is an incredibly customized power device, specifically tailored to meet individual needs. It has the ability to complete power conversion with high precision and excellent stability, without requiring external components. On the other hand, the switching power supply is a general power supply device that must be equipped with peripheral components to achieve power conversion. It can be adjusted and optimized based on specific circumstances when being used.
Additionally, the power module's structure is simple and utilizes fewer components, resulting in lower manufacturing costs. Typically, it employs open-loop control without feedback control. On the contrary, the switching power supply demands a more intricate structure, incorporating a large number of components. It usually integrates closed-loop control to guarantee the stability and precision of the output, thus leading to a higher manufacturing cost.
In general, power modules and switching power supplies each have their own advantages and disadvantages, and their application fields and needs are also different. No matter what type of power conversion equipment, it provides solid and reliable power support for our production and life.
Instructions for use of the power module
1.Before using a power module, it is important to carefully read and understand the product manual. Familiarize yourself with the various parameters and usage methods of the product. Each power module may have unique specifications such as voltage, current, input and output modes. Choose the appropriate power module that fits your specific needs. By taking these simple steps, you can ensure the safe and efficient use of your power module.
2.Another important aspect to consider when using the power module is the wiring method and polarity. It is crucial for users to connect the input and output ports correctly, so as to prevent any potential damages or circuit failures. Additionally, it is essential to take notice of the polarity of red and black wires, as proper wiring can avoid any dangerous occurrences due to reversed connection. By following these guidelines, users can ensure efficient and safe usage of the power module.
3.When using a power module, it is important for users to prioritize ventilation and heat dissipation. As the module consumes electric energy and generates heat during operation, proper air circulation is necessary. If the module is used for an extended period, it is crucial to keep an eye on its temperature. Taking prompt measures to dissipate heat, should it exceed the limit specified in the product manual, is advisable.
4.In order to ensure the safe and proper use of the power module, it is important for users to be mindful of overload and short circuit. If the module is overloaded beyond its capacity, it may cause damage or even result in the module burning out. Likewise, a short circuit can cause unexpected disruptions in the circuit or potentially damage the module.users should pay attention to avoid overload and short circuit when using the power module. It is recommended that the user pay attention to the power and load of the device during use, and use a suitable fuse to protect the power module.
