The UNOWT 75W Series (UNOWT3075) is an open-frame power supply (board-mounted power supply) for embedded use in industrial equipment. Designed based on a compact 2"×6" class form factor, it is 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 confirmation 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 according to production volume, from small-lot prototyping and evaluation to small and medium-scale production, as well as large-scale 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 (options for chassis/cover/remote ON/OFF)
In addition to the standard board, configurations can be selected according to mounting and operational requirements, such as with chassis, chassis + 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.
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 and includes resistance items under 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 cooling, as well as information on mounting orientations (A-F), which can be used when considering thermal design and mounting conditions inside equipment enclosures.
Effective Use Cases
- When adopting a compact 2"×6" class board-mounted power supply as an internal power supply for industrial equipment
- When selecting configurations (chassis/cover, with or without 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) in light of disturbances such as ESD, EFT, and surge
- When evaluating adoption based on derating conditions due to constraints in mounting orientation, cooling conditions, and ambient temperature
- When organizing power supply requirements including equipment-side operating conditions such as installation altitude and momentary voltage drop requirements (SEMI F47)
Applications
Widely applicable as an internal power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
