The UNOWT 50W Series is an open-frame power supply (board-type power supply) designed for installation inside industrial equipment. Based on a compact 2"×5.2" 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 supply 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 Reasons to Choose: 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, production launch, and post-mass 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 even 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"×5.2" 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 for applicable conditions for each model). Equipped with short-circuit/overvoltage/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 Part15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity (Resistance)
Immunity compliant with EN55035/BS EN 55035, with resistance items including 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 method (multiple orientations) and ambient temperature, as well as conditions for forced air cooling (>15 CFM)/natural air cooling, which can be used for thermal design and installation condition studies inside the enclosure.
Effective Implementation Cases
- When adopting a compact 2"×5.2" class board-type power supply as an internal power supply for industrial equipment
- When selecting configurations such as chassis/cover and with or without remote ON/OFF according to installation and maintenance conditions
- When proceeding with power supply selection for mass production adoption on 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 considering resistance requirements (EN61000-4-x) in light of disturbances such as ESD, EFT, and surge
- When installation orientation, cooling conditions, and ambient temperature constraints exist and adoption feasibility needs to be evaluated based on derating conditions
- When organizing adoption conditions including installation environment conditions (e.g., altitude conditions, SEMI F47, etc.)
Applications and Use Cases
Widely applicable as an internal power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
