GDY series products are a high isolation constant voltage series. This type of product has obvious advantages such as small size, high efficiency, high isolation voltage and high reliability. It is suitable for digital signal processing circuits, distributed power supply systems and circuits using small power supplies and analog circuits with low voltage stability requirements. Especially suitable for outdoor equipment and anti-lightning circuits with higher isolation voltage requirements. It is not suitable for circuits with input voltage variation ranges exceeding ±10% and circuits with extremely high output voltage stability requirements.
This manual provides the general characteristics, electrical specifications and mechanical dimensions of the Yaohua GDY‑XXS‑W5 series DC‑DC converters. It includes data on input and output voltage ranges, power rating, efficiency, temperature performance and isolation strength.
The document also gives practical guidance on load conditions, short‑circuit protection, ripple mitigation and parallel operation of multiple converters. Users are advised on recommended load percentages, the need for external PTC fuses and optional filtering components for low‑noise applications. This manual is written in Chinese.
