Information about MEAN WELL EPS-15-27
The MEAN WELL EPS-15-27 is an ultra-compact, high-efficiency open-frame PCB power supply designed specifically for space-constrained industrial, automation, and embedded systems. Featuring a miniature footprint of just 1.8" x 2.5" (63.5 x 45.7 mm) and a low-profile height of 24 mm, this module integrates seamlessly into tight equipment enclosures. It operates across a wide universal input range of 85 to 264 V AC while maintaining an exceptionally low no-load power consumption of under 0.3 W, making it an ideal choice for green energy initiatives, IoT nodes, and standby power architectures.
A key strength of the EPS-15-27 lies in its robust fanless design using natural air convection, enabling silent, maintenance-free operation across temperature environments ranging from −30 °C to +70 °C. The nominal 27 V DC output can be precisely fine-tuned onboard (24.3–29.7 V DC) via an integrated potentiometer to compensate for line drops and fit specific system load demands. Built-in protection circuitry safeguards against short circuits, overloads, and overvoltage, ensuring long-term operational resilience. Backed by global safety standards like UL62368-1 and TUV alongside a solid 3-year manufacturer warranty, this module delivers reliable performance for compact designs.
