Power Supply

This series includes the AD25002S and AD25003S models, featuring a rugged and high-power-density design, specifically developed to meet space-saving requirements and industrial applications. All models come with built-in dry contact alarm signals and O-ring diodes, supporting redundant system configurations, and are equipped with overvoltage protection, overload protection, and short-circuit protection to ensure reliable operation. The design is flexible, allowing installation on T.35 rails or easily mounted on walls using the included mounting brackets. All models comply with RoHS standards, carry the CE mark, and are UL508 certified.
