Stable power supply for digital systems
This switched-mode power supply transforms mains AC power into a 5V DC output. It provides a constant current of up to 40A to power sensitive electronic circuits.
Connectivity via protected terminal block
It features nine clearly labeled screw terminals for live, neutral, ground, and multiple voltage outputs. It includes a hinged plastic cover to prevent accidental contact.
Metal chassis designed for passive heat dissipation
The perforated aluminum structure facilitates airflow and heat dissipation from the internal components. Its robust design ensures circuit integrity in industrial environments.
Integrated protection against electrical failures
The device has safety certifications that guarantee protection against power surges and short circuits. This prevents damage to both the power supply itself and connected equipment.
Front potentiometer for fine voltage adjustment
It incorporates an ADJ regulator that allows for precise calibration of the final output voltage. This function is essential for compensating for voltage drops in long-distance cabling.
Optimized for LED lighting and digital signage
Its high amperage capacity is suitable for 5V LED strip installations and illuminated signs. It allows for centralized power supply to multiple devices from a single unit.
Professional solution for installations in continuous use
Manufactured with selected components to withstand extended duty cycles in B2B applications. It offers a balanced technical ratio for distributors and maintenance services.

What is the maximum actual load recommended to connect to this power supply?
Although the power supply is rated for 40A, in professional installations it is recommended not to exceed 80% of its total capacity continuously. This helps maintain an optimal operating temperature and prolongs the lifespan of the internal capacitors.
Is it compatible with WS2812B type LED strip controllers?
Yes, it is ideal for addressable LED pixels and strips that operate at 5V. Its 40A output allows it to power a large number of LED nodes, ensuring uniform brightness throughout the installation without noticeable voltage drops.
Does it require any specific maintenance or cleaning?
Since it relies on passive cooling through perforations, dust accumulation inside the chassis must be avoided. Installation in clean, dry locations is recommended, and periodic cleaning with compressed air should be performed to prevent overheating.
Can the fountain be installed outdoors or in humid areas?
No, this fountain has an open design with an indoor protection rating. If you require outdoor use, it must be housed in a watertight enclosure with adequate ventilation to protect it from moisture, rain, and other external elements.
A versatile and robust power supply designed to meet the most demanding technical standards. Its reliability makes it an essential component for professional electronics and lighting projects.
