The UNOWT 100W Series is an open-frame power supply (PCB power supply) for internal equipment integration in industrial devices. Based on a compact 2.4"x6.1" class board size, it is structured as a standard series that makes power selection easier while considering mounting conditions.
Equipped with protection circuits (short circuit/overvoltage/overcurrent) and compliant with Energy Efficiency Level VI (ErP/DoE), emissions (FCC/EN(CISPR)/BS EN), and immunity (EN55035, EN61000-4-x), you can verify power requirements necessary for mass production design based on specifications. Options such as chassis/cover, remote ON/OFF, and output voltage adjustment (±10%) are available, enabling configuration according to operating conditions.
| 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, production launch, and post-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 for mass production adoption. |
Key Features
1) Compact 2.4"x6.1" 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 chassis-mounted (UNBWT3100), chassis with cover (UNSWT3100), and with or without remote ON/OFF. As a market-standard product, it is also ideal for replacing 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/overvoltage/overcurrent protection circuits.
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 (Resistance)
Immunity complies with EN55035/BS EN 55035, including EN61000-4-2/-3/-4/-5/-6/-8/-11 test items.
6) Derating and Mounting Information Useful for Installation and Thermal Design
Provides derating information based on mounting orientation (A-F) and cooling conditions (natural convection/forced air cooling >15CFM), as well as output derating relative to input voltage, useful for evaluating thermal design and mounting conditions inside enclosures.
Effective Use Cases
- When adopting a compact 2.4"x6.1" class PCB power supply as a built-in power supply for industrial equipment
- When selecting configurations such as chassis/cover and remote ON/OFF according to mounting and maintenance conditions
- When proceeding with power supply selection for mass production while meeting efficiency requirements (Energy Efficiency Level VI)
- When organizing power supply conditions according to equipment requirements, including output voltage adjustment (±10%)
- When selecting a power supply in line with emission requirements (FCC/EN(CISPR)/BS EN) for EMC design
- When considering resistance requirements (EN61000-4-x) with external disturbances such as ESD, EFT, and surge in mind
- When evaluating adoption based on derating conditions due to constraints in mounting orientation, cooling conditions, and ambient temperature
- When organizing power supply conditions including equipment-side operating conditions such as momentary voltage drop requirements (SEMI F47: applicable for input over 200V) 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.
