UMOATN3018
|
The UMOATN 18W Series is an 18W-class embedded open-frame power supply designed primarily for medical equipment applications compliant with IEC 60601-1. Featuring a 2xMOPP-compliant insulation design, it ensures high safety for medical devices intended for patient contact and enables power supply designs that meet stringent medical safety requirements. In addition, its high-efficiency design compliant with Energy Efficiency Level VI (ErP/DoE) achieves both energy savings and stable power delivery. It includes protection against short circuit, overvoltage, overcurrent, and overtemperature, and complies with various EMC/immunity standards including IEC 60601-1-2. The compact 2x3-inch board size is suitable for integration into space-constrained enclosures, making it an ideal power solution for medical devices where reliability and safety are top priorities, such as diagnostic equipment, therapeutic devices, and other medical peripheral equipment.

The UxOATN 18W Series (UxOATN3018) is an open-frame power supply (PCB power supply) for medical equipment suitable for embedded applications. Designed for integration into medical, home appliance, and I.C.T. equipment, it features a space-saving 2" x 3" PCB size, making power selection easier based on mounting conditions.
This AC-DC switching power supply allows confirmation of power requirements (protection, emissions, immunity, etc.) for mass production design based on the conditions specified in the datasheet.
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review assuming 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. We also support semi-custom solutions and assist with power selection from the specification review stage for mass production adoption. |
Key Features
1) Open-frame power supply (PCB power supply) for medical equipment
An open-frame power supply for medical equipment designed for integration as an internal device power supply. The 2" x 3" PCB size space-saving design makes it easy to adopt even in limited enclosure mounting conditions.
2) Technical standards and protection circuits
Safety standards vary depending on the model classification (M / H / N). Equipped with short-circuit protection / overvoltage protection / overcurrent protection, with overtemperature protection available as an option.
3) Efficiency
Energy Efficiency Level VI (ErP/DoE) compliant, enabling selection in accordance with Commission Regulation (EU) 2019/1782 and DOE 10 CFR part 429 and 430 requirements.
4) EMC (Emissions)
FCC Part15-B / FCC Part18-B, EN(CISPR)55032-B / 55011-B / 55014-B, and BS EN 55032 / 55011 / 55014-1 compliant. Please refer to "Standards and Compliance" for details.
5) Immunity
EN55035 / BS EN 55035, as well as requirements such as EN60601-1-2 / EN55014-2, with immunity items specified under EN61000-4-2/-3/-4/-5/-6/-8/-11. Please refer to "Standards and Compliance" for details.
Effective Implementation Cases
