The brilliance of technology always shines through communication and exchange. At the 2025 Shanghai Power Automation Exhibition, Leyu Electric invites you to join us, discuss the latest industry trends, and explore new technological ideas.

Leyu Electronics Co., Ltd. is a professional manufacturer of switching power supplies, inverters, and solar controllers.This article describes in detail the precautions that need to be taken when using a switching power supply.

Learn how switching power supplies work, their components, benefits, and common uses in electronics and industry. Expert guide from Leyu Electric.

Choosing the correct power inverter is essential for maintaining your electrical devices' performance, safety, and longevity. Depending on your system's power quality requirements, you can select a square wave, modified sine wave, or pure sine wave inverter for residential, commercial, or off-grid applications.

Systems must be reliable, efficient, and built to last in industrial automation. The LRS-350 Switching Power Supply from Leyu Electric meets all these needs. It is small but mighty and works well in many uses, such as LED lighting and programmable logic controllers (PLCs). Let's look at why the LRS-350 is a key part of today's automation setups.

Today, many people focus on new tech. However, they often forget one key part of a computer: the power supply unit (PSU). The PSU changes electricity from the wall into the computer's power. This helps the computer work well and without problems. Leyu is a well-known company that makes computer parts. Leyu has many kinds of PSUs. Some are made for powerful gaming computers, while others are cheaper and good for basic setups.

A switching power supply changes wall power (AC) into steady DC power using fast switching. It works well and takes up little space. But it has high voltage, gets hot, and can be a fire risk. So, safety is paramount when using it.

In the ever-evolving realm of renewable energy, picking the right inverter is like selecting the heart of your energy setup. As demand grows for converting direct current (DC) power into alternating current (AC) with reliability, inverters become essential in various applications. Among these, the industrial-grade 3000W inverter with a bright LCD shines brightly as a hallmark of innovation—it merges power with precision in an intelligent design.

Have you ever been puzzled by a faint buzzing or whirring from your electronic devices? You're not alone, and it's not the gremlins at work. This common phenomenon is often linked to the power supplies in our gadgets, the unsung heroes that keep everything running smoothly but sometimes noisily.

Leyu Electronics Co., Ltd. is a professional manufacturer of switching power supplies, inverters, and solar controllers based in Yueqing, Zhejiang Province, China. Since its founding in 2007, Leyu has been committed to delivering reliable and cost-effective power solutions to customers worldwide.

Power inverters are essential in modern homes, RVs, and solar energy systems. Whether you're looking to power a refrigerator in an off-grid cabin or charge your laptop in a campervan, understanding how power inverters work and how to choose the right one is critical. This guide will break it all down in a clear, beginner-friendly way.

Switching power supplies are used in many devices, but not everyone knows what they do. They are essential for modern electronics, powering phones, computers, and industrial machines.
To begin with, it’s important to understand how power supplies work and why they matter. They convert electrical energy into a form that devices can use, helping them run efficiently and reliably.
