MORNSUN Power Supply Solutions for IoT and New Energy Applications

CONTENTS


Internet of Things (IoT) technologies are growing increasingly popular as they have become an essential aspect of our everyday lives. They have penetrated almost every industry while making the world a smarter, greener, and more convenient place. New connectivity technologies are being introduced year after year to ease the life of homeowners and business owners worldwide.

 

However, while connectivity is an essential aspect of IoT, design engineers are faced with the challenge of maintaining long-term online to offline communication even when the smart devices are in stand-by mode. An efficient  AC/DC power supply ensures continuous communication between devices and limits its stand-by power consumption in smart homes and industrial IoT environments.

We are heading toward an increasingly smarter but also greener future. At least, environmental damage and climate change are making new energy sources a more urgent priority for businesses and governments worldwide. The money investments behind renewable-energy power plants tend to be quite significant. Therefore, it is even more essential to invest in power supplies that can properly balance electricity supply and demand on the power grid, despite the challenges posed by the intermittent nature of many renewable energy sources.

 

Power generation for IoT infrastructures and renewable energy systems can result in different challenges based on their environment and specific applications. In both scenarios, failing to select high-efficient and high-performing power supplies can cripple the long-term performance and lifespan of the system or device. For this reason, we will share more details on how we at MORNSUN can help you with your power design of IoT devices and renewable energy systems.


What is IoT?

The Internet of Things (IoT) describes the network of physical objects that are embedded with sensors, software, and other technologies to ensure the connection and data exchange with other devices and systems over the Internet. Some examples of IoT technology deployment include an office room adjusting ambient light levels to human presence or commands, health monitoring machines, or home regulation technology that helps regulate our lives automatically for more efficient resource usage and comfortable living.

 

IoT technologies often heavily rely on the data collected from IoT devices like sensors and actuators. All of these always-on, active 24/7 sensors will consume power. A reliable and high-efficiency power supply helps the device to balance stable performance and decrease the environmental impact.

In short, powering IoT devices means a low-power consumption AC/DC power supply is required. As typical IoT devices spend a lot of time in stand-by mode, the AC/DC converter should combine high efficiency at both low and full load with the ability to handle load currents that are fast, transient and dynamic. In other words, you may want to look for AC/DC power supplies that are physically high-efficiency, reliable, and above all, affordable.

 

For example, smart thermostats are among the most common IoT-enabled devices in smart homes and other interconnected environments. These devices need to combine high-density and very low input current with a compact size and low costs. In this case, it is even more important to find a power supply truly suitable for smart thermostat applications.

What Do We Mean With “New Energy”?

On the other hand, “new energy” refers to energy obtained from renewable resources, hence why it is also called “renewable energy”. This type of energy is crucial in many different areas such as electric generation, water and air cooling or heating, transportation, off-grid electric energy services, and more. Today, new energy sources are also powering mobility options like electric vehicles, trains, and even airplanes.

The demand for renewable energy is rapidly rising and will continue to grow more into the future as the need to fight global warming and climate change takes center stage. New energy markets and technologies are developing fast. These forms of energy are becoming cheaper, giving rise to a growing demand for devices that rely on this efficient, economical power solution.

 

To this end, we at MORNSUN have developed power modules that support an ultra-wide Input voltage range for a large variety of IoT devices.

 

These power supplies are also compatible with new energy systems like solar control panels, automobile control and drive systems, and more. Some devices like the MORNSUN LS-R3 series and the MORNSUN LD-R2 series are designed specifically to meet these needs.

 

The MORNSUN Power Supply LD-R2 and LS-R3 Series 

LD-R2 Series

Due to the development of IoT and the smart home trend, the requirement of household appliances for safety and dimensions is important. Smart home appliances include various power supplies and electronic components that enable graphics, wireless communications, software interfaces, and other functions. All the power supplies and electronic components have an impact on the overall safety of the product. In addition, the capacitors design, EMI class B without external components requirement, and the low-no-load power consumption make the product perfect for home appliances.

LS-R3 Series

Miniaturization is becoming the in-thing for end-use devices as they continue to grow smaller and lighter, requiring a higher level of integration technology to boost their ease of use. Engineers have been puzzled for years on how to find a balance between size, cost, performance, design cycles, reliability, ease of use, and personalization in designing and producing electrical products.
