The 12V, 300W ultra-slim power supply integrates the functions of a switching mode power supply (SMPS) and an LED driver transformer, specifically designed for indoor linear lighting, commercial lighting, and LED strip projects. Featuring an ultra-compact linear design with a thickness of less than 22mm, it can be easily installed into tight spaces such as light boxes, display cases, and illuminated signs, effectively solving the problem of bulky traditional power supplies.

The housing is made of high-strength aluminum alloy, offering excellent thermal conductivity and impact resistance to effectively protect the internal circuitry. Natural convection cooling ensures stable long-term operation under full load. As a constant-voltage driver, it delivers a stable 12V DC output with a maximum current of 25A and a rated power of 300W, capable of simultaneously powering multiple high-power LED strips or modules, meeting the high-current demands of commercial displays, advertising signage, and similar applications.

In terms of electrical performance, the power supply supports a wide input voltage range of 90–264 VAC, making it compatible with global power grids. It features built-in active power factor correction (PFC), achieving a conversion efficiency of over 90%, meeting high energy efficiency standards and significantly reducing power consumption and heat generation. With its low-profile design and compact layout, the product can serve both as an AC-DC converter and a switching transformer, offering versatile applications in one unit.

The device features a comprehensive safety protection mechanism, integrating overload protection (OLP), short-circuit protection (SCP), overvoltage protection (OVP), and overtemperature protection (OTP). It automatically shuts off the output when an abnormal load occurs and resumes operation automatically once the fault is cleared, ensuring that both the LED strip and the driver system are protected from damage. Additionally, with an output ripple of less than 120 mV, it effectively prevents light flickering and extends the lifespan of the LEDs.

This product is widely suitable for indoor lighting, LED strip projects, light box signage, commercial display illumination, and industrial equipment power supply. Its ultra-slim aluminum housing and metallic finish not only enhance heat dissipation efficiency but also support various installation methods (wall-mounted, rail-mounted, or suspended). Certified with CE and ROHS safety standards, the product offers reliable quality and serves as an ideal alternative to traditional bulky power supplies, providing a high-efficiency, safe, and compact power solution for your lighting projects.
