This document introduces the technical parameters and features of the DAD-V4 series AC/DC module power supply with dual output of 25W. The product has two naming methods: dual-route common ground output and dual-route isolated voltage-stabilizing output, with built-in input filtering circuit and FCI filtering method. The input voltage range is AC165~265V or AC85~265V, and the output voltage can be selected as DC 3.3V, 5V, 12V, 15V, 24V, 28V, 48V or 110V, with high voltage accuracy and low ripple and noise. The product also features multiple protection functions, shock resistance design, and electromagnetic compatibility design.
This datasheet describes the technical parameters of the Dilong DAD-V4 series 25 W module power supply, including input voltage ranges, selectable output voltages, accuracy, efficiency, and protection features. It also lists environmental specifications, mechanical dimensions, and pin assignments.
Key features include dual‑output configurations (isolated or common‑ground), high efficiency (>75%), over‑current protection, strong isolation (up to 1500 VAC), and compliance with IEC and UL standards for industrial and military applications. This manual is written in Chinese.
