RoHS (10 Substances) Non-Use Certificate
The UNOPT 75W Series is an open-frame power supply (board-mounted power supply) for built-in equipment applications in industrial devices. Based on a compact 2"×5.9" board size, this series is structured to facilitate power supply selection in consideration of mounting conditions.
In addition to protection circuits for short circuit, overvoltage, and overcurrent (+ overtemperature: optional), the series allows you to verify power supply requirements that must be organized for mass production design, including Energy Efficiency Level VI (ErP/DoE), emissions (FCC/EN(CISPR)/BS EN), and immunity (EN55035, EN61000-4-x), based on specifications.
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide consistent support from specification review with mass production in mind 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 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"×5.9" standard series (chassis/cover options available)
In addition to the standard board (UNOPT3075), configurations with chassis (UNBPT3075) and chassis + cover (UNSPT3075) are available, allowing selection according to mounting and protection requirements. As a market-standard product, it is also ideal for replacing existing units.
2) Technical standards and protection circuits
Compliant with IEC/EN 62368-1 (BS EN 62368-1) technical standards (please inquire for model-specific conditions). Equipped with short circuit, overvoltage, and overcurrent protection, with overtemperature protection available as an option.
3) High-efficiency design (Energy Efficiency Level VI)
Energy Efficiency Level VI (ErP/DoE) compliant, enabling selection in accordance with EU Regulation (EU) 2019/1782 and DOE 10 CFR Part 429/430 requirements.
4) EMC (Emissions)
Emissions compliant with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity
Compliant with EN55035/BS EN 55035, with immunity items specified for EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Specifications useful for organizing industrial equipment adoption requirements (PFC/voltage adjustment/altitude/SEMI F47, etc.)
Features include PFC (power factor), inrush current, output voltage adjustment (variable range specified), operating altitude up to 5,000 m, OVC III (2000 m), SEMI F47 (with input condition notes), consideration for requirements assuming dusty environments (as specified), and a 5-year warranty.
Effective Use Cases
- When adopting a compact 2"×5.9" class board power supply for built-in industrial equipment
- When selecting configurations such as chassis/cover options according to mounting and protection requirements
- When proceeding with power supply selection for mass production adoption under 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) against disturbances such as ESD, EFT, and surge
- When evaluating adoption including equipment-side operating conditions such as altitude and SEMI F47
Applications
Widely applicable as a built-in power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
