> NVVV's 24V Switch Power Supplies
In today's electrified world, the need for efficient and reliable power conversion is more critical than ever. From powering the smallest of household gadgets to running large industrial machinery, the versatility and safety of electrical power are paramount. This is where voltage conversion plays a crucial role, bridging the gap between the power supplied by utilities and the specific needs of various devices and systems.> NVVV at the Russian Power Exhibition in June 2023
In June 2023, our NVVV team proudly participated in the Russian Power Exhibition. During the event, we showcased our reliable, high-quality products, attracting the attention of industry experts and customers alike.> INSTALLATION OF OPEN FRAME AND U CHANNEL AC-DC POWER SUPPLIES
In the industrial field, AC-DC power modules are usually supplied in two forms: open frame and U-slot. These modularly designed power supplies are widely used in terminal devices that need to be embedded and installed, and are protected by the device housing. Below we will discuss the key considerations when installing open frame and U-slot power supplies from the aspects of safety, electromagnetic compatibility (EMC) and thermal management, and discuss their practical applications in combination with product specifications.> What are the Functions of SMPS?
In today’s fast-paced world, where electronics power everything from our homes to our workplaces, a reliable and efficient power supply is critical. Switched-mode power supplies (SMPS) are the unsung heroes behind many devices, quietly converting electricity to ensure they function smoothly. Whether it’s the laptop you’re using, the TV in your living room, or complex industrial machinery, SMPS ensures these devices receive the right power, efficiently and safely. But what exactly does SMPS do? Why is it so important, and how can you make sure it's working correctly? Let's dive into its types, importance, maintenance, and even how it compares with other power systems like UPS (uninterruptible power supply), So as to understand SMPS in one step.+86-18968803336
