The UNOWT 75W Series (UNOWT3075) is an open-frame power supply (board-mounted power supply) for embedded use in industrial equipment. Designed based on a compact 2"x6" class configuration, it serves as a standard series that facilitates power selection in consideration of mounting conditions.
Equipped with protection circuits (short circuit/overvoltage/overcurrent), it complies with Energy Efficiency Level VI (ErP/DoE) and allows verification of power requirements that must be organized for mass production design, including emissions (FCC/EN(CISPR)/BS EN) and immunity (EN55035, EN61000-4-x), based on specifications.
| UNIFIVE Reasons to Choose Us: 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, production launch, and post-production follow-up. Based on standard products, we offer flexible supply options according to production volume, from small-lot prototyping and evaluation to small- and medium-scale production, and high-volume manufacturing. We also support semi-custom solutions and assist with power selection from the specification review stage for mass production adoption. |
Key Features
1) Compact 2"x6" Standard Series (Options for Chassis/Cover/Remote ON/OFF)
In addition to the standard board type, configurations can be selected to match mounting and operational requirements, including with chassis, with chassis and cover, and with or without remote ON/OFF. As a market-standard product, it is also ideal for replacing existing power supplies.
2) Technical Standards and Protection Circuits
Compliant with 62368-1 and 100V-240V standards (please contact us for details on safety certifications). Equipped with short circuit/overvoltage/overcurrent protection.
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)
Emissions comply with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity
Immunity complies with EN55035/BS EN 55035, with resistance items per EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Derating Information Based on Mounting and Cooling Conditions
Provides derating curves (reference values) based on forced air cooling (>15 CFM) and natural convection, as well as information on mounting orientations (A-F), which can be used for thermal design and installation condition evaluation within the enclosure.
Effective Use Cases
- When adopting a compact 2"x6" class board-mounted power supply as an internal power supply for industrial equipment
- When selecting configurations such as chassis/cover and remote ON/OFF options according to installation and maintenance conditions
- When proceeding with power selection for mass production adoption under efficiency requirements (Energy Efficiency Level VI)
- When selecting a power supply in EMC design in accordance with emission requirements (FCC/EN(CISPR)/BS EN)
- When considering resistance requirements (EN61000-4-x) in light of disturbances such as ESD, EFT, and surge
- When evaluating adoption feasibility based on derating conditions due to mounting orientation, cooling conditions, and ambient temperature constraints
- When organizing power requirements including equipment-side operating conditions such as installation altitude and voltage sag requirements (SEMI F47)
Applications
Suitable for a wide range of embedded power supply applications in industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
