Range: 3.1 – 3.6 V DC Isolation Voltage: 3000 V AC between input and output Dimensions (L x W x H): 76.2 mm x 50.8 mm x 24 mm Weight: approx. 81 g Safety & EMC Certificates: UL62368-1, TUV BS EN/EN62368-1, EAC, CCC, CE Form Factor: Open-frame PCB power supply (3" x 2") Manufacturer Warranty: 3 Years Information about MEAN WELL EPS-25-3.3 The MEAN WELL EPS-25-3.3 is an advanced, board-mountable open-frame PCB power supply built in an industry-standard 3" x 2" compact footprint (76.2 x 50.8 mm). Designed for modern industrial, telecommunications, and embedded system applications, this module features a low-profile height of just 24 mm, making it ideal for tight space allocations inside equipment enclosures. Operating on a universal input range of 85 to 264 V AC, it maintains an exceptionally low no-load power consumption of less than 0.3 W, supporting eco-friendly energy standards and efficient standby performance. A key strength of the EPS-25-3.3 lies in its dependable fanless design using natural air convection, which enables completely silent and maintenance-free operation across temperature extremes from −30 °C to +70 °C. It incorporates an onboard LED status indicator for immediate power visibility, and the nominal 3.3 V output can be precisely fine-tuned via an integrated potentiometer within 3.1 to 3.6 V DC. Built-in protection systems against short circuits, overloads (hiccup mode), and overvoltage provide maximum reliability. Backed by global safety approvals such as UL62368-1 and TUV alongside a solid 3-year manufacturer warranty, this module offers superior quality for high-density electronic assemblies.
