The GU300 product family was specifically designed to deliver enhanced performance while minimizing the effort required in system integration.
The GU300 family is approved to both medical and industrial safety standards, complying to both Medical (IEC/UL60601-1, 3rd Edition) and Industrial/ITE (IEC/UL62368) safety standards within the same SKU. This is one of the most notable attributes of the GU300 family of products and, when paired with a design optimized for seamless integration, the GU300 stands out as the ultimate solution for Medical, Test & Measurement, Industrial and virtually any other application necessitating optimal performance.
Featuring next-generation technology, the GU300 was designed with built-in digital control and monitoring capability via PMBus to facilitate more precise in-system operation, user controllability, and overall versatility of these power units. The GU300 is constructed with the highest quality components, such as long-life electrolytic capacitors. Furthermore, the power supply design ensures that these components are not pushed to their maximum output ratings. For example, the long-life electrolytic capacitors operate below their threshold and ESR ratings in order to extend the life of the end equipment and minimize field service needs.

300W of output power in a 3" x 5" x 1.5" open frame package.
> 7-year (min) e-cap life.
Meeting Class B EMI Levels with margin ensures less effort by the system designer to integrate a power supply into the end equipment.
Built-in protections against unstable operational environments minimize the need for implementing at the system level, resulting in shorter development time and reduced cost.
Use of high-quality electrolytic capacitors well below their threshold and ESR ratings help extend the life of the end equipment and minimize field service needs.
High convection rating minimizes the need to rely on forced air, thereby increasing reliability and minimizing system cost by eliminating the need for a fan.
SL Power local technical support capabilities provide real-time help in solving potential design problems which could otherwise cause revenue loss due to delays in end product introduction.
Extensive global presence can support customers product needs as they migrate from development to production, frequently in multiple locations around the world.
