The UNOWT 75W Series (UNOWT3075) is an open-frame power supply (board-mounted power supply) designed for installation inside industrial equipment. 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) and allows you to verify power supply requirements that should be organized in mass production design based on specifications, including emissions (FCC/EN(CISPR)/BS EN) and immunity (EN55035, EN61000-4-x).
| UNIFIVE Reasons to Choose: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review with mass production in mind, certification acquisition, production launch, to 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-scale mass production. We also support semi-custom solutions and assist with power supply selection from the specification planning 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 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
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 as protection circuits.
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 immunity requirements.
6) Derating Information Based on Mounting Method and Cooling Conditions
Provides derating curves (reference values) for 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 mounting condition studies inside equipment enclosures.
Effective Implementation Cases
- When adopting a compact 2"x6" class board power supply as a built-in power source for industrial equipment
- When selecting configurations such as chassis/cover and with or without remote ON/OFF according to mounting and maintenance conditions
- When proceeding with power supply selection for mass production adoption under the premise of meeting 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 selecting based on immunity requirements (EN61000-4-x) considering disturbances such as ESD, EFT, and surge
- When there are constraints on mounting orientation, cooling conditions, or ambient temperature and adoption needs to be evaluated based on derating conditions
- When organizing power supply requirements including equipment operating conditions such as installation altitude and momentary voltage drop requirements (SEMI F47)
Applications and Examples
Widely applicable as a built-in power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
