Information about MEAN WELL EPS-45-48-C
The MEAN WELL EPS-45-48-C is a high-efficiency switching power supply featuring an enclosed metallic structure (-C), derived from the standard EPS-45 series platform. Designed for space-constrained industrial, control, and embedded equipment, the protective cover enhances mechanical durability and safety against accidental contact. Operating on a broad universal input range of 90 to 264 V AC, it maintains an exceptionally low no-load power consumption of under 0.3 W, supporting eco-friendly energy initiatives and efficient standby performance.
A key strength of the EPS-45-48-C 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. An onboard LED power indicator provides clear visual confirmation of operational status, while the nominal 48 V output can be fine-tuned via an onboard trimmer (43.2–52.8 V DC) to compensate for voltage drops. Built-in protection circuitry safeguards against short circuits, overloads (hiccup mode), and overvoltage, ensuring maximum operational resilience. Backed by global safety standards like UL62368-1 and TUV alongside a solid 3-year manufacturer warranty, this module delivers reliable performance.
