Switched Mode Power Supply (SMPS), or switch mode power supply, is a power supply device that regulates power through switches. It is widely used in many fields, among which 3D printers and embroidery machines are particularly common. Such devices have high requirements for power supply, and SMPS has the characteristics of stability, energy saving and high efficiency, which can well meet these requirements. So, why is SMPS particularly suitable for 3D printers and embroidery machines?

Why is SMPS particularly suitable for 3D printers and embroidery machines?

First of all, 3D printers and embroidery machines require stable and controllable power supply when they are working. Traditional linear power supplies are prone to power waste, and when the load changes greatly, the output voltage is unstable, which will directly affect the operation of the equipment. SMPS converts AC power into DC power through high-frequency switching technology, and can adjust the output voltage and current according to the actual load requirements to ensure that the equipment can work stably. For example, during the printing process of a 3D printer, it is necessary to achieve precise power distribution between the heating nozzle, the driving stepper motor and the control motherboard. Any carelessness may lead to printing failure, and the efficient power conversion capability of SMPS makes it an ideal power supply choice.

Secondly, SMPS is small and lightweight, making it very suitable for integration into 3D printers and embroidery machines. Compared with traditional linear power supplies, SMPS has a higher conversion efficiency, which means that it requires smaller components to convert the same power, thereby reducing the overall weight and volume of the device. This is especially important for 3D printers and embroidery machines with compact designs and limited space. For example, some portable 3D printers and small embroidery machines on the market usually use built-in SMPS in their power supply design, which not only saves space but also increases the convenience of the equipment.

24vdc power supply is also very common in many 3D printers and embroidery machines, especially in those devices with high requirements for power supply stability. 24vdc power supply can provide stable and lasting power support, avoiding the impact of voltage fluctuations on printing accuracy or embroidery quality. Since 3D printers require stable power supply when heating nozzles, controlling motors and printing, the use of 24vdc power supply can ensure the smooth operation of the equipment while working, while reducing energy consumption.

In addition, the high efficiency and energy saving characteristics of SMPS are also one of the reasons why it is widely used in 3D printers and embroidery machines. 3D printers and embroidery machines consume considerable amounts of power when working for a long time, and SMPS can significantly reduce power loss and reduce the overall energy consumption of the equipment. Traditional linear power supplies have large power losses when the load is light or unstable, especially when the embroidery machine is processing complex patterns, it needs to frequently change the motor's operating speed and power, which requires very high efficiency of the power supply, and SMPS can be dynamically adjusted according to actual needs to ensure that it can work in the most efficient way under different workloads, thereby achieving energy saving.

How much power do SMPSs use for 3D printers and embroidery machines?

When discussing specific applications, the power requirements required by different devices vary greatly. 3D printers and embroidery machines usually have different power requirements for power supplies, so the selected SMPS power is also different. For ordinary home or small 3D printers, the output power of the power supply is generally between 150W and 300W, while large industrial 3D printers may require higher power supplies, with a power range of up to 500W or even higher.

Taking a typical 150W 3D printer as an example, if its operating voltage is 24V, the required current can be calculated by a simple formula:

I= P/U​Where,

P is power,

U is voltage, and

I is current.

Substitute the data:

I= 150W/24V=6.25A

This means that when the printer is operating normally, the power supply needs to provide a current of about 6.25A. Therefore, the SMPS must be able to stably provide sufficient current to ensure the normal operation of the 3D printer.

For embroidery machines, their power requirements are generally slightly higher than 3D printers, especially when running complex patterns or high-speed operation, the stability of the power supply is particularly critical. Some large commercial embroidery machines may require a 500W or even higher power SMPS, while small household embroidery machines may only require a power supply of about 200W. These different power requirements make the flexibility of the SMPS particularly important, because it can adjust the output power according to the actual needs of the equipment to ensure the stable operation of the equipment under various working conditions.

In some cases, a 24vdc power supply is ideal for powering embroidery machines, especially in applications that require high stability and low energy consumption. This power supply can provide a stable 24V DC power supply, which allows the embroidery machine to maintain high efficiency during long-term operation and reduce the impact of voltage fluctuations on product quality.

How does the school network laptop charging cabinet use SMPS to improve efficiency?

In addition to 3D printers and embroidery machines, switching power supply is also widely used in school network laptop charging cabinets. This device is usually used to charge multiple laptops or other mobile devices, and has high requirements for power stability and efficiency. SMPS can ensure a stable supply of current when charging multiple devices at the same time through efficient power conversion technology.

In the charging cabinet, the advantage of SMPS is that it can cope with the needs of multiple charging devices. Different models of laptops have different requirements for charging voltage and current. Traditional power supplies may find it difficult to meet these requirements at the same time, which can easily lead to slow or uneven charging speed. SMPS can provide suitable voltage and current for each device through precise power control technology, thereby improving overall charging efficiency.

For example, if a school's charging cabinet needs to charge 30 laptops at the same time, and the charging power of each laptop is 60W, then the total power demand of the charging cabinet can be calculated by the formula:

Ptotal=N×Psingle, where

Ptotal is the total power, N is the number of devices, and Psingle is the power of each device. Substitute the data:

Ptotal=30×60W=1800W

Therefore, the charging cabinet needs to be equipped with an switched-mode power supply that can provide at least 1800W of power to ensure that all devices can be charged efficiently at the same time.

In addition, the high efficiency of SMPS enables the charging cabinet to significantly reduce energy consumption when working for a long time, avoiding the waste of power under heavy load of traditional power supply. At the same time, the small size of SMPS also helps the design of the charging cabinet to be more compact and save space.

Why does the watering machine need to use SMPS?

In the field of agriculture, watering machines are widely used, especially in large areas of farmland and greenhouses. Watering machines can realize automatic watering, which greatly improves agricultural production efficiency. The application of SMPS in irrigation machines is mainly to provide stable power support to ensure the continuity and accuracy of the irrigation process.

Irrigation machines usually need to run for a long time, especially in the dry season, and may need to work continuously for hours or even days. This places high demands on the stability of the power supply. Switching mode power supply can ensure that the irrigation machine can always obtain stable power supply during long-term operation through efficient power conversion technology, avoiding equipment shutdown or damage due to unstable voltage or insufficient current.

In addition, the energy-saving characteristics of SMPS are also very important for the operation of irrigation machines. Agricultural electricity is usually used in large areas of farmland, and the cost of electricity supply is high, so how to save energy becomes an important consideration. Compared with traditional linear power supplies, SMPS can increase the power conversion efficiency to more than 90%, which means that under the same power consumption, the irrigation machine can obtain more available power, thereby reducing operating costs.

For example, assuming that the power demand of a watering machine is 500W and the working voltage is 48V, the required current can be calculated by the formula:

I= P/U

Substitute the data:

I= 500W/48V=10.42A

This means that the SMPS needs to stably output a current of 10.42A to ensure the normal operation of the watering machine. The precise control capability of the SMPS ensures that the watering machine can obtain sufficient power support under various operating conditions.

Conclusion

Switched Mode Power Supply (SMPS) has become the preferred power supply solution for equipment such as 3D printers, embroidery machines, school network laptop charging cabinets and watering machines due to its high efficiency, stability and energy saving. Especially when the equipment requires 24 volt DC power supply, 24vdc power supply can provide reliable and efficient power support for the equipment. It can not only ensure the stable operation of the equipment under various complex working conditions, but also greatly improve the efficiency of power utilization and reduce the operating cost of the equipment through precise power control. In the future, with the continuous advancement of technology, the application prospects of SMPS in more fields will be broader.
