The UNOWT 100W Series is an open-frame power supply (board-mounted power supply) designed for built-in equipment applications. Based on a compact 2.4"×6.1" class board size, it is configured 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 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). Configuration options such as chassis/cover, remote ON/OFF, and output voltage adjustment (±10%) enable consideration according 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 assuming mass production adoption, certification acquisition, and production launch to post-mass production follow-up. Based on standard products, we offer flexible supply according to volume scale, from small-lot prototyping and evaluation to small and medium-scale production and large-volume manufacturing. 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 2.4"×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 suitable for replacement of existing models.
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 compliant with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity
Immunity compliant with EN55035/BS EN 55035, with immunity items 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, useful for thermal design and mounting condition evaluation within enclosures.
Effective Use Cases
- Adopting a compact 2.4"×6.1" class board-mounted power supply as a built-in power source for industrial equipment
- Selecting configurations (chassis/cover, with or without remote ON/OFF) according to mounting and maintenance conditions
- Proceeding with power supply selection for mass production adoption assuming compliance with 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 emission 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 on mounting orientation, cooling conditions, and ambient temperature
- Organizing power supply conditions including equipment-side operating requirements such as voltage sag requirements (SEMI F47: applicable above 200V input) and altitude conditions
Applications
Widely applicable as a built-in power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
