RoHS (10 Substances) Non-Use Certificate
The UNOWT 75W Series (UNOWT3075) is an open-frame power supply (board-level power supply) designed for embedded use in industrial equipment. Designed as a standard series that simplifies power selection based on mounting conditions, it is built on a compact 2"x6" class form factor.
Equipped with protection circuits (short circuit/overvoltage/overcurrent), it allows verification of power requirements necessary for mass production design based on specifications, including Energy Efficiency Level VI (ErP/DoE), emissions (FCC/EN(CISPR)/BS EN), and immunity (EN55035, EN61000-4-x).
| 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, mass 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 large-scale mass production. 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 (Chassis/Cover/Remote ON/OFF Options)
In addition to the standard board, 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 suitable for replacing existing models.
2) Technical Standards and Protection Circuits
Compliant with 62368-1 and 100V-240V standards (please contact us for details on safety standards). Equipped with short circuit protection/overvoltage protection/overcurrent protection.
3) Efficiency
Energy Efficiency Level VI (ErP/DoE) compliant, enabling selection based on the requirements of Commission Regulation (EU) 2019/1782 and DOE 10 CFR part 429 and 430.
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, covering EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Derating Information Based on Mounting Method and Cooling Conditions
Provides derating curves (reference values) assuming forced-air cooling (>15 CFM) and natural convection, as well as information on mounting orientations (A-F), which can be used when considering thermal design and mounting conditions within the enclosure.
Effective Use Cases
- When adopting a compact 2"x6" class board-level power supply as an embedded power source in industrial equipment
- When selecting configurations based on mounting and maintenance conditions, such as chassis/cover and presence or absence of remote ON/OFF
- When proceeding with power selection for mass production adoption under efficiency requirements (Energy Efficiency Level VI)
- When selecting a power supply in accordance with emission requirements (FCC/EN(CISPR)/BS EN) in EMC design
- When considering resistance requirements (EN61000-4-x) with external disturbances such as ESD, EFT, and surge in mind
- When installation orientation, cooling conditions, and ambient temperature constraints require evaluation based on derating conditions
- When organizing power requirements including equipment-side operating conditions such as installation altitude and voltage dip requirements (SEMI F47)
Applications and Examples
Widely applicable as an embedded power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
