The UNOWT 75W Series (UNOWT3075) is an open-frame power supply (board-mounted power supply) for built-in equipment applications designed for industrial devices. Based on a compact 2"x6" 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 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 you to verify power supply 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, 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-volume manufacturing. 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 (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 + 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
Complies 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 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, 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 air cooling, as well as information on mounting orientations (A-F), which can be used for thermal design and mounting condition evaluation within equipment enclosures.
Effective Use Cases
- When adopting a compact 2"x6" class board power supply as a built-in power supply for industrial equipment
- When selecting configurations (chassis / cover, with or without remote ON/OFF) according to mounting and maintenance requirements
- When proceeding with power supply selection for mass production adoption under Energy Efficiency Level VI requirements
- 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 supply requirements including equipment operating conditions such as installation altitude and voltage dip requirements (SEMI F47)
Applications
Widely applicable as a built-in power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
