LED lighting systems have a significant impact on our lives with their energy efficiency, compactness, reliability, and longer lifetime. In addition to domestic, industrial, and street lighting, they also serve as effective architectural lighting. Pulsed LED power supplies are used to power single or groups of power LEDs that require a regulated output current. No matter how the input voltage fluctuates, the output parameters will not change. This quality makes them particularly suitable for settlements with unstable voltages.
S-3000-30switching power supply product features:
(1) Affordable price and high reliability
(2) High efficiency and low working temperature
(3) With short circuit and overload protection
(4) Soft start current effectively reduces AC input impact
S-3000-30 AC/DC power supply selection tips:
Power must be based on consumer power and load type:
(1) When the equipment is used in conjunction with inductive load appliances, the power must be 3 to 5 times the load power consumption! (Fluorescent lamps, electric motors, pumps, air conditioners, refrigerators, freezers, etc.).
(2) When the device is used for users of capacitive loads, the selected power must be 5 to 10 times larger than the power consumption of the load! (pulse chargers, LED drivers, pulse power supplies, etc.).
(3) The nominal power of the equipment must be 20-30% higher than the consumer's load capacity under active loads (heaters, electric ovens, stoves, stoves, incandescent lamps, etc.). This is due to the high starting current of the load. When the load is turned on and during repeated short-duration modes, the load significantly exceeds the nominal parameters specified in the load characteristics for short periods.
Kindly note that if these instructions are not followed, the unit may be overloaded and stop functioning, and the warranty does not cover the damage. To correctly select the power of the device, it is recommended to consult a specialist. The output voltage of the switching power supply is adjustable and can also be customized by customers. If you need other output voltages, please contact us.
Small size, high efficiency up to 88%, greatly saving energy, stable work, high reliability.

> 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
