Certificate of Non-Use for RoHS (10 Substances)
The UNOWT 50W Series is an open-frame power supply (board-type power supply) designed for embedded use in industrial equipment. Based on a compact 2"x5.2" class form factor, it is structured as a standard series that facilitates power supply selection in consideration of mounting conditions.
Equipped with protection circuits (short-circuit/overvoltage/overcurrent), it allows you to verify power requirements that should be addressed 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 Reasons to Choose: 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 volume requirements, from small-lot prototyping and evaluation to small- and medium-scale production and 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"x5.2" Market-Standard Series (Chassis/Cover/Remote ON/OFF Options)
In addition to the standard board, configurations can be selected according to installation and operational 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 inquire about applicable conditions for each model). Equipped with short-circuit protection/overvoltage protection/overcurrent 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 compliant with FCC Part 15-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 Based on Mounting Method and Cooling Conditions (Reference Values)
Provides derating curves (reference values) according to mounting orientation (multiple orientations) and ambient temperature, as well as conditions for forced air cooling (>15 CFM) and natural convection, useful for thermal design and installation condition review within enclosures.
Effective Use Cases
- When adopting a compact 2"x5.2" class board power supply as an embedded power source for industrial equipment
- When selecting configurations such as chassis/cover and with or without remote ON/OFF according to installation and maintenance requirements
- When proceeding with power supply 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 resistance to disturbances such as ESD, EFT, and surge, and selecting based on immunity requirements (EN61000-4-x)
- When installation orientation, cooling conditions, and ambient temperature are constrained and adoption needs to be evaluated 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.
