The UxOAT 300W Series is an embedded AC-DC switching power supply (open-frame / PCB-mounted power supply) for medical equipment. With a compact 3"×5" board size, this series is designed to facilitate power selection and evaluation assuming installation inside equipment enclosures.
Key conditions required for mass-production design-such as efficiency (up to 92%), PFC (power factor), emission/immunity, and protection circuits (short circuit / overvoltage / overcurrent / Brown In / Brown Out)-are clearly defined, making it useful for confirming adoption requirements (safety standards vary by model category).
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review for mass production to certification acquisition, 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 manufacturing. We also support semi-custom solutions and assist with power supply selection from the specification planning stage for mass production. |
Key Features
1) 300W Class × Compact 3"×5" Embedded Power Supply
Designed as a standard embedded power supply for industrial equipment, featuring a PCB size of 3"×5". Its configuration facilitates the organization and evaluation of power requirements based on enclosure installation conditions. Ideal for replacement of existing units.
2) Technical Standards and Protection Circuits
Safety standards vary by model category (M / H / N) within the series (please contact our sales office for details on each model). Equipped with short circuit protection / overvoltage protection / overcurrent protection / Brown In / Brown Out protection.
3) Efficiency and PFC (Power Factor)
Efficiency reaches up to 92%. Power factor (PFC) specifications are also provided to assist in defining input-side requirements (ACIN100V: 0.95, ACIN230V: 0.9).
4) EMC (Emission)
Compliant with FCC (Part15-B / Part18-B), CE (EN(CISPR)55032-B / 55011-B / 55014-B), and BS EN (55032 / 55011 / 55014-1) (conditions apply when an AC inlet filter is installed in the user’s metal enclosure).
5) Immunity
In accordance with EN55035 / BS EN 55035, EN60601-1-2 / BS EN60601-1-2, EN55014-2 / BS EN55014-2, and related requirements, the series supports immunity standards EN61000-4-2 / -3 / -4 / -5 / -6 / -8 / -11.
6) Derating Information for Forced Air Cooling (>20.5CFM) / Natural Convection
Derating curves are provided for both natural convection and forced air cooling (>20.5CFM), supporting thermal design and installation condition evaluations within equipment enclosures.
Effective Use Cases
- When a 300W-class embedded power supply for medical equipment is required with space-saving 3"×5" mounting
- High efficiency (up to 92%) is a priority, including thermal and power condition considerations
- Considering adoption while organizing input conditions (voltage and frequency), including PFC (power factor)
- Organizing protection requirements including Brown In / Out to mitigate operational risks from input fluctuations
- Selecting a power supply aligned with emission requirements (FCC / EN(CISPR) / BS EN, etc.) in EMC design
- Evaluating adoption based on derating under forced air / natural convection conditions
- Organizing power conditions including installation altitude, OVC III, SEMI F47, and other equipment-side operating requirements
Applications
