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.

Industrial systems demand more than just power—they demand precision, reliability, and resilience. From fire control panels and ventilation systems to elevators, pumps, and automated manufacturing lines, the quality of power supply directly impacts operational stability and safety. That’s why more and more system integrators and industrial engineers are turning to the switching mode power supply (SMPS)—a compact, efficient, and highly adaptable solution designed to meet modern industrial standards. Let’s explore the key questions driving SMPS adoption across today’s industrial power infrastructure.> Key Benefits of Using a Switching Mode Power Supply in LED Power
From vibrant LED billboards in urban centers to subtle ambient lighting in modern architecture, LED technology is now the go-to choice for both indoor and outdoor lighting solutions. Its energy efficiency, long lifespan, and design flexibility have revolutionized the lighting industry. But behind every reliable LED display or light strip is a power source working silently to ensure stable, safe, and efficient performance: the Switching Mode Power Supply (SMPS). With growing demands for reliability in harsh environments, strict EMC compliance, high efficiency, and maintenance-free performance, choosing the right SMPS has become just as important as selecting the right LED itself. In this article, we explore the key benefits of using a switching mode power supply in LED power applications, and why more LED system integrators and manufacturers are turning to SMPS to future-proof their lighting projects.+86-18968803336
