The UNOWT 50W Series is an open-frame power supply (board-type) designed for integration into industrial equipment. It is configured as a standard series to facilitate power supply selection, based on mounting requirements and within a compact 2"×5.2" class.
Equipped with protection circuits (short-circuit / overvoltage / overcurrent), it meets key mass production power requirements such as Energy Efficiency Level VI (ErP / DoE), emissions (FCC / EN(CISPR) / BS EN), and immunity (EN55035, EN61000-4-x), all of which can be confirmed based on specifications.
| UNIFIVE As a power supply manufacturer with over 35 years of development experience, we offer consistent support from specification planning for mass production to certification acquisition, ramp-up, and post-production follow-up. Based on our standard products, we provide flexible supply for small-lot prototyping, small to medium-scale production, and large-volume manufacturing. We also support semi-customization and assist with power supply selection from the specification planning stage. |
Main Features
1) Market-standard compact 2"×5.2" series (with chassis / cover / remote ON/OFF options)
In addition to the standard board, configurations with a chassis, with chassis and cover, and with or without remote ON/OFF can be selected according to the mounting and operation conditions. Also ideal for replacing existing models.
2) Technical Standards & Protection Circuits
Conforms to 62368-1 and 100V–240V standards (please inquire about applicable conditions for each model). Includes protection circuits such as short-circuit, overvoltage, and overcurrent protection.
3) Efficiency
Compliant with Energy Efficiency Level VI (ErP / DoE) and selectable based on requirements such as Commission Regulation (EU) 2019/1782 and DOE 10 CFR part 429 and 430.
4) EMC (Emission)
Emissions comply with FCC Part15-B / EN(CISPR)55032-B / BS EN 55032.
5) Immunity
Immunity conforms to EN55035 / BS EN 55035, with resistance to EN61000-4-2 / -3 / -4 / -5 / -6 / -8 / -11.
6) Derating (reference values) based on mounting and cooling conditions
Derating curves (reference values) are provided for multiple mounting orientations and ambient temperatures, along with conditions for forced air cooling (>15 CFM) / natural convection, supporting thermal design and implementation considerations.
Ideal Use Cases
- Desire to use a compact 2"×5.2" class board power supply for industrial equipment integration
- Need to select configurations with chassis / cover, and remote ON/OFF based on installation or maintenance requirements
- Need to choose a power supply for mass production that meets efficiency requirements (Energy Efficiency Level VI)
- Want to select a power supply based on EMC emission requirements (FCC / EN(CISPR) / BS EN)
- Need to consider immunity to disruptions such as ESD, EFT, surge, and select based on EN61000-4-x requirements
- Need to assess suitability based on derating due to mounting orientation, cooling conditions, and ambient temperature constraints
- Want to organize adoption conditions including environmental installation factors (e.g., altitude, SEMI F47)
Applications / Examples
Widely applicable as an integrated power supply for industrial devices.
- Industrial equipment
- Control devices
- Information and communication devices
- Peripheral devices, etc.
