The UOB 6W Series (UOB305) is an open-frame power supply (board-level power supply) suitable for equipment integration. Designed for use as an internal power supply in I.C.T. / AV equipment, it features a space-saving PCB size of 1.3" x 3", making power selection easier based on mounting conditions. It is an AC-DC switching power supply, allowing verification of power requirements (protection, EMC, etc.) in mass production design based on the conditions specified in the datasheet.
Equipped with short-circuit, overvoltage, and overcurrent protection circuits, it supports design and evaluation in consideration of emission (FCC / EN(CISPR) / BS EN) and immunity (EN55035, EN61000-4-x) requirements.
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide consistent support from specification review for mass production adoption to certification acquisition, mass production launch, and post-production follow-up. Based on standard products, we offer flexible supply from small-lot prototyping and evaluation to small- and medium-scale production, as well as large-volume production according to your quantity needs. We also support semi-custom solutions and assist with power supply selection from the specification review stage toward mass production adoption. |
Key Features
1) Open-frame for internal equipment integration (inlet type)
An open-frame (inlet type) power supply designed for integration as an internal power supply. Its space-saving design allows easy adoption even under limited mounting conditions inside equipment enclosures.
2) Technical standards and protection circuits
Compliant with 60065-1 / 60950-1 / 62368-1 and 100V standards (check applicable conditions for each model). Equipped with short-circuit protection / overvoltage protection / overcurrent protection.
3) Efficiency
Efficiency is up to 60% (as specified in the datasheet).
4) EMC (Emission)
FCC Part15-B / EN(CISPR)55032-B / BS EN 55032 compliant. Please refer to "Standards and Compliance" for details.
5) Immunity
Based on EN55035 / BS EN 55035, designed in consideration of ESD, EFT, surge, etc. (EN61000-4-x). Please refer to "Standards and Compliance" for details.
Effective Use Cases (Selection Guide)
