RoHS (10 Substances) Non-Use Certificate
The UNOWT 75W Series (UNOWT3075) is an open-frame power supply (PCB power supply) designed for embedded use in industrial equipment. Based on a compact 2"×6" class form factor, it is designed as a standard series that facilitates power supply selection in consideration of mounting conditions.
Equipped with protection circuits (short circuit/overvoltage/overcurrent), it allows confirmation of power supply 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 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 even large-volume 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) Compact 2"×6" standard series (chassis/cover/remote ON/OFF options)
In addition to the standard PCB, configurations can be selected according to installation and operation 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 replacement of existing units.
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 compliant with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity
Immunity compliant 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 air cooling, as well as information on mounting orientations (A-F), which can be used for thermal design and installation condition studies within equipment enclosures.
Effective Implementation Cases
- When adopting a compact 2"×6" class PCB power supply for embedded use in industrial equipment
- When selecting configurations such as chassis/cover and with or without remote ON/OFF according to installation 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 disturbances such as ESD, EFT, and surge in mind
- When evaluating adoption based on derating conditions due to constraints on mounting orientation, cooling conditions, and ambient temperature
- When organizing power supply requirements including equipment-side operating conditions such as installation altitude and voltage dip requirements (SEMI F47)
Applications and Use Cases
Widely applicable as an embedded power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
