Certificate of Non-Use of RoHS (10 Substances)
The UNOWT 75W Series (UNOWT3075) is an open-frame power supply (board-mounted power supply) for embedded equipment applications in industrial devices. Designed for a compact 2"x6" class configuration, it serves as a standard series that facilitates power supply selection based on mounting conditions.
Equipped with protection circuits (short circuit/overvoltage/overcurrent), it complies with Energy Efficiency Level VI (ErP/DoE), as well as emission standards (FCC/EN(CISPR)/BS EN) and immunity standards (EN55035, EN61000-4-x), allowing verification of power requirements necessary for mass production design based on specifications.
| 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 from small-lot prototyping and evaluation to small and medium-scale production, as well as large-volume production according to required quantities. We also support semi-custom solutions and assist with power supply 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 according to 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 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 circuits.
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 (Emission)
Compliant with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032 emission standards.
5) Immunity
Compliant with EN55035/BS EN 55035, with immunity items 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) based on forced air cooling (>15 CFM) and natural convection cooling, as well as information on mounting orientations (A-F), supporting thermal design and mounting condition evaluation within enclosures.
Effective Use Cases
- When adopting a compact 2"x6" class board power supply as an internal power source for industrial equipment
- When selecting configurations such as chassis/cover and remote ON/OFF according to mounting and maintenance conditions
- When proceeding with power supply 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) with external disturbances such as ESD, EFT, and surge in mind
- When evaluating adoption feasibility based on derating conditions due to mounting orientation, cooling conditions, and ambient temperature constraints
- When organizing power supply requirements including equipment-side operating conditions such as installation altitude and voltage dip requirements (SEMI F47)
Applications
Widely applicable as an embedded power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
