DESCRIPTION

The UE28-SPA-OP is a 28W AC to DC open-frame switching power supply designed for embedded and built-in power applications that require high efficiency, compact size, and long-term operational stability. This internal AC-DC power module is CE certified and engineered with a mature switching topology to ensure stable voltage regulation and dependable performance in continuous-use environments. Supporting a universal high-voltage AC input range of 176–264VAC, it is well suited for global markets and export-oriented equipment, especially applications that operate under wide and fluctuating mains conditions. The power supply delivers a regulated 19V DC output at 0.01–1.50A, providing clean and consistent power for sensitive electronic circuits, digital control boards, and display-driven systems. With standby power consumption limited to a maximum of 0.3W and compliance with IEEE 802.3at/af standards, this open-frame power supply helps reduce no-load energy loss, supports eco-design requirements, and contributes to overall system energy efficiency and thermal optimization.

Designed for compact integration, the UE28-SPA-OP features an open-frame PCB structure that allows flexible mechanical layout and easy installation inside space-constrained enclosures, making it an ideal solution for OEM and ODM customers developing customized electronic products. Its balance of performance, cost efficiency, and reliability makes it a practical internal power solution for industrial automation equipment, smart home control systems, security and access control devices, communication terminals, and portable or semi-portable electronic products. Typical applications include touch screen panel controllers, building intercom systems, small power monitoring tools, electronic photo frames, Blu-ray players, conference system terminals, embedded display systems, control panels, smart terminals, and low-power multimedia devices. With its wide input range, stable 19V output, low standby power, compact open-frame design, and broad application compatibility, the UE28-SPA-OP is a dependable and economical AC-DC power supply choice for manufacturers seeking efficient internal power modules for industrial, commercial, and smart electronics markets.
