Designed for space-constrained industrial, control, and embedded equipment, this module features a low-profile height of just 29 mm (PCB version), making it an ideal choice for tight enclosures. 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-45-3.3 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 3.3 V output can be fine-tuned via an onboard trimmer (3.1–3.6 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.
