RoHS (10 Substances) Non-Use Certificate
The UNOPT 75W Series is an open-frame power supply (board-mounted power supply) designed for embedded use in industrial equipment. Based on a compact 2"x5.9" board size, the series configuration makes it easy to select a power supply in consideration of mounting conditions.
In addition to protection circuits for short circuit, overvoltage, and overcurrent (+ overtemperature: optional), you can verify power supply requirements that need to be addressed in 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).
| UNIFIVE Reasons for Being Chosen: 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, mass production launch, and post-production follow-up. Based on standard products, we offer flexible supply options according to volume, from small-lot prototyping and evaluation to small- and medium-scale production and large-volume production. We also support semi-custom solutions and assist with power supply selection from the specification review stage toward mass production adoption. |
Key Features
1) Standard 2"x5.9" Compact 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 contact us for model-specific conditions). Equipped with short-circuit protection, overvoltage protection, 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 comply with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity
EN55035/BS EN 55035 compliant, with immunity items specified under 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.)
Includes PFC (power factor), inrush current, output voltage adjustment (variable range specified), operating altitude up to 5,000m, OVC III (2000m), SEMI F47 (with notes on input conditions), considerations for requirements assuming dusty environments (as specified), and a 5-year warranty.
Effective Use Cases
- When adopting a compact 2"x5.9" class board power supply as an embedded power source for 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 based on meeting efficiency requirements (Energy Efficiency Level VI)
- When selecting a power supply in accordance with emission requirements (FCC/EN(CISPR)/BS EN) for EMC design
- When selecting based on immunity requirements (EN61000-4-x) considering disturbances such as ESD, EFT, and surge
- When evaluating adoption including equipment-side operating conditions such as altitude requirements and SEMI F47
