The UNOWT 100W Series is an open-frame power supply (PCB power supply) for embedded equipment applications in industrial devices. Based on a compact 2.4"×6.1" class board size, 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 confirmation of power supply requirements necessary for 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). Options such as chassis/cover, remote ON/OFF, and output voltage adjustment (±10%) are available, enabling configuration tailored to operating conditions.
| 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-production follow-up. Based on standard products, we offer flexible supply 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 with power supply selection from the specification review stage for mass production adoption. |
Key Features
1) Compact 2.4"×6.1" Standard Series (Chassis/Cover/Remote ON/OFF Options)
In addition to the standard board (UNOWT3100), configurations can be selected according to mounting and operational requirements, including with chassis (UNBWT3100), with chassis + cover (UNSWT3100), and with or without remote ON/OFF. As a market-standard product, it is also ideal for replacing existing units.
2) Technical Standards and Protection Circuits
Compliant with 62368-1 and 100V-240V standards (model-specific conditions must be confirmed). Equipped with short circuit protection/overvoltage protection/overcurrent protection.
3) High-Efficiency Design (Energy Efficiency Level VI)
Supports Energy Efficiency Level VI (ErP/DoE) efficiency requirements, enabling selection based on Commission Regulation (EU) 2019/1782 and DOE 10 CFR part 429 and 430 requirements.
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, with resistance items including EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Derating and Mounting Information Useful for Installation and Thermal Design
Provides derating information according to mounting orientation (A-F) and cooling conditions (natural convection/forced air cooling >15CFM), as well as output derating relative to input voltage, supporting enclosure thermal design and mounting condition evaluation.
Effective Use Cases
- Adopting a compact 2.4"×6.1" class PCB power supply as an internal power source for industrial equipment
- Selecting configurations such as chassis/cover and with or without remote ON/OFF according to mounting and maintenance conditions
- Proceeding with power supply selection for mass production adoption under efficiency requirements (Energy Efficiency Level VI)
- Organizing power supply conditions according to equipment requirements, including output voltage adjustment (±10%)
- Selecting a power supply in EMC design in accordance with emissions requirements (FCC/EN(CISPR)/BS EN)
- Selecting based on immunity requirements (EN61000-4-x) considering disturbances such as ESD, EFT, and surge
- Evaluating adoption feasibility based on derating conditions due to constraints in mounting orientation, cooling conditions, and ambient temperature
- Organizing power supply conditions including equipment-side operating requirements such as voltage dip requirements (SEMI F47: applicable for input over 200V) and altitude conditions
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.
