The UxOAT 300W Series is an embedded AC-DC switching power supply for medical equipment (open-frame / PCB power supply). With a compact 3"x5" board size, the series is designed to facilitate power supply 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 well organized, making it useful for confirming adoption requirements (safety standards vary by model classification).
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide end-to-end support from specification review for mass production adoption to certification acquisition, production launch, and post-mass-production follow-up. Based on standard products, we offer flexible supply according to production volume, from small-lot prototyping and evaluation to small- and medium-scale production, and up to large-scale production. We also support semi-custom solutions and assist with power supply selection from the specification review stage toward mass production adoption. |
Key Features
1) 300W class x Compact 3"x5" embedded power supply
A standard embedded power supply for industrial equipment featuring a PCB size of 3"x5" in a compact design. Structured to facilitate the organization and evaluation of power requirements based on in-enclosure mounting conditions. Ideal for replacement of existing units.
2) Technical standards and protection circuits
Safety standards differ depending on model classification (M/H/N) (please contact our sales office for details on each model's safety standards). Equipped with short circuit protection/overvoltage protection/overcurrent protection/Brown In/Brown Out protection.
3) Efficiency and PFC (Power Factor)
Efficiency of up to 92%. Power factor (PFC) specifications are also provided to assist in organizing input-side requirements (ACIN100V: 0.95, ACIN230V: 0.9).
4) EMC (Emissions)
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
Based on requirements such as EN55035/BS EN 55035, EN60601-1-2/BS EN60601-1-2, and EN55014-2/BS EN55014-2, the series supports immunity items EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Forced air cooling (>20.5CFM) / natural convection derating information
Derating curves are provided for both natural convection and forced air cooling (>20.5CFM), supporting thermal design and installation condition studies within the enclosure.
Effective Use Cases
- When a 300W-class embedded power supply for medical equipment is required and selection is based on space-saving 3"x5" installation
- When prioritizing high efficiency (up to 92%) and organizing power requirements including heat generation and power conditions
- When considering adoption while organizing input conditions (voltage/frequency) including PFC (power factor)
- When organizing protection requirements including Brown In/Out to reduce operational risk considering input fluctuations
- When selecting a power supply aligned with emission requirements (FCC/EN(CISPR)/BS EN, etc.) in EMC design
- When evaluating adoption feasibility based on derating under forced air/natural cooling conditions
- When organizing power requirements including equipment operating conditions such as installation altitude, OVC III, and SEMI F47
