UxOAT 300W Series (UxOAT3300) is an embedded AC-DC switching power supply (open-frame/PCB power supply) designed for industrial equipment. With a compact 3"×5" board size, the series is structured to facilitate power supply selection and evaluation assuming installation inside equipment enclosures.
Key mass-production design requirements 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 depending on the 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 adoption to certification acquisition, mass production launch, and post-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 large-scale mass production. We also support semi-custom solutions and assist with power supply selection from the specification planning stage toward mass production adoption. |
Key Features
1) 300W class × Compact 3"×5" embedded power supply
A standard embedded power supply for industrial equipment with a 3"×5" PCB size compact design. Structured to facilitate requirement organization and evaluation based on enclosure installation conditions. Ideal for replacement from existing models.
2) Technical standards and protection circuits
Safety standards differ depending on the model category (M/H/N) (please contact our sales office for details of 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 is up to 92%. Power factor (PFC) specifications are also provided to assist with input-side requirement planning (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
Based on requirements such as EN55035/BS EN 55035, EN60601-1-2/BS EN60601-1-2, and EN55014-2/BS EN55014-2, the product supports immunity items EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Forced air cooling (>20.5CFM)/Natural convection derating information
Derating curves assuming natural convection (Free Convection) and forced air cooling (>20.5CFM) are provided for thermal design and installation condition review inside enclosures.
Effective Use Cases
- When a 300W-class embedded power supply is required and selection is based on space-saving 3"×5" installation
- When prioritizing high efficiency (up to 92%) and organizing requirements including heat generation and power conditions
- When considering adoption while organizing input-side conditions (voltage/frequency), including PFC (power factor)
- When organizing protection requirements including Brown In/Out to reduce operational risks from input fluctuations
- When selecting a power supply in accordance with EMC emission requirements (FCC/EN(CISPR)/BS EN, etc.)
- When evaluating adoption based on derating under forced air/natural convection conditions
- When organizing power supply conditions including equipment-side operating requirements such as installation altitude, OVC III, and SEMI F47
