TDK-Lambda Switching Power Supply 15V DC 15W PCB Mount, Universal Input, 1A Output KWS15A-15

The TDK-Lambda KWS15A-15 is a compact, encapsulated AC-DC switching power supply designed for PCB mounting applications where a stable and reliable DC voltage source is required. This model delivers a regulated 15V DC output at up to 1A current, providing a total power output of 15W. Its universal input accommodates supply voltages from 85V AC up to 265V AC, as well as 120V to 370V DC, making it suitable for use in global industrial and instrumentation systems.

The KWS15A-15 is engineered to occupy minimal space, with overall dimensions of 50.8 mm in length, 25.4 mm in width, and a depth of 24 mm. This footprint is ideal for integration into compact enclosures and densely populated circuit boards. The device weighs only 60 grams, which assists in reducing stress on the PCB and supports a wide range of mounting orientations.

This power supply series is recognized for its efficiency, achieving a typical rate of 84%. Higher efficiency reduces energy consumption and eases heat management for sensitive components nearby. Overvoltage and overcurrent protective features are integrated into the unit to safeguard connected equipment, and the robust encapsulated construction further supports operation in challenging industrial environments.

The model operates reliably across an extended temperature range from -10°C up to 85°C, making it suitable for applications exposed to varied operational conditions. The plastic enclosure complies with UL94V-0 standards, offering high flame retardancy for additional safety. Conducted emissions and electromagnetic interference are controlled to meet several international EMC and safety standards, including EN 55011, EN 55022-B, EN 61000-4 series, IEC/UL/CSA/EN 62368-1, FCC Class B, and VCCI-B.

TDK-Lambda's KW series, including the KWS15A-15, is widely used for powering industrial automation, test and measurement setups, communication equipment, and broadcast devices. The robust input and output specifications allow it to support instrumentation globally without requiring separate voltage models. The design includes overvoltage and overcurrent protection, and it is recommended not to operate continuously under short-circuit conditions. The lightweight and universal-functionality make it an optimal choice for OEMs and panel builders integrating reliable power supplies into their assemblies.

Typical industrial use cases are factory automation, process control, embedded instrumentation, telecommunication systems, and broadcast electronics. The compactness and high efficiency enable deployment in space-critical control cabinets or mobile test equipment. International safety and EMC compliance ensures hassle-free global acceptance and deployment.
