The UNOWT 50W Series is an open-frame power supply (board-mounted power supply) designed for embedded use in industrial equipment. Based on a compact 2"×5.2" class form factor, it is structured as a standard series that facilitates power selection in consideration of mounting conditions.
Equipped with protection circuits (short-circuit/overvoltage/overcurrent), it allows you to verify power requirements that should be organized in 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 consistent 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 volume, from small-lot prototyping and evaluation to small- and medium-scale production, as well as large-volume production. We also support semi-custom solutions and assist in power selection for mass production from the specification review stage. |
Key Features
1) Compact 2"×5.2" market-standard series (chassis/cover/remote ON/OFF options)
In addition to the standard board type, configurations can be selected according to installation and operation requirements, including with chassis, with chassis and cover, and with or without remote ON/OFF. Ideal for replacing existing products.
2) Technical standards and protection circuits
Compliant with 62368-1 and 100V-240V standards (please contact us for applicable conditions for each model). Equipped with short-circuit/overvoltage/overcurrent protection circuits.
3) Efficiency
Compliant with Energy Efficiency Level VI (ErP/DoE), 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 EN61000-4-2/-3/-4/-5/-6/-8/-11 test items.
6) Derating based on mounting method and cooling conditions (reference values)
Derating curves (reference values) according to mounting method (multiple orientations) and ambient temperature, as well as forced air cooling (>15 CFM)/natural convection conditions, are provided for consideration in thermal design and installation conditions within the enclosure.
Effective Implementation Cases
- When adopting a compact 2"×5.2" class board-mounted power supply for embedded use in industrial equipment
- When selecting configurations according to installation and maintenance conditions, such as chassis/cover and with or without remote ON/OFF
- When proceeding with power selection for mass production adoption based on 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 immunity requirements (EN61000-4-x) in view of disturbances such as ESD, EFT, and surge
- When installation orientation, cooling conditions, and ambient temperature constraints require evaluation based on derating conditions
- When organizing adoption conditions including installation environment requirements (e.g., altitude conditions, SEMI F47, etc.)
Applications
Widely applicable as an embedded power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
