RoHS(10 Substances) Non-Use Certificate
The UOH 18W Series (UOH318) is an open-frame power supply (board-mounted power supply) suitable for embedded equipment applications. Designed for use as an internal power supply in I.C.T./AV equipment, it emphasizes miniaturization (Ultra Small Size) and stable operation (Stability), making it easier to verify power requirements (protection, emissions, immunity, etc.) in mass production design.
This AC-DC switching power supply is equipped with protection circuits for short circuit, overvoltage, overcurrent, and overtemperature. It is designed and evaluated in consideration of emission standards (CISPR 32/FCC Part15) and immunity requirements (EN55024).
| UNIFIVE Reasons to Choose: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review for mass production adoption to certification acquisition, mass production launch, and post-production follow-up. Based on our standard products, we offer flexible supply from small-lot prototyping and evaluation to small- and medium-scale production, and even large-volume production. We also support semi-custom solutions and assist with power supply selection from the specification planning stage toward mass production adoption. |
Key Features

An open-frame power supply designed for integration as an internal power source. Featuring an Ultra Small Size, it is easy to adopt even under limited mounting conditions within equipment enclosures.
2) Technical standards and protection circuits
Compliant with 60950-1 (please contact us regarding safety standards for each model). Equipped with short-circuit protection/overvoltage protection/overcurrent protection/overtemperature protection.
3) Efficiency
A series designed with emphasis on energy efficiency.
4) EMC (Emissions)
Compliant with CE CISPR 32 EN55032/FCC Part15 Class B. Please refer to "Standards and Compliance" for details.
5) Immunity
Designed in consideration of requirements based on EN55024/A1:2001. Please refer to "Standards and Compliance" for details.
Effective Use Cases
- When integrating an open-frame (board-mounted) power supply as an internal power source
- When mounting space or height constraints require power selection based on board dimensions and mounting conditions
- When aiming to reduce operational risk with protection functions such as short circuit, overvoltage, overcurrent, and overtemperature
- When selecting a power supply in EMC design in accordance with emission requirements (CISPR 32/FCC Part15 Class B)
- When selecting a power supply considering external noise environments based on immunity requirements (EN55024)
Applications
