Certificate of Non-Use of RoHS (10 Substances)
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"×5.9" board size, this series configuration makes it easy to select a power supply while considering mounting conditions.
In addition to protection circuits for short circuit, overvoltage, and overcurrent (+ overtemperature: optional), you can verify power supply requirements that should 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 is chosen because: 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-mass production follow-up. Based on standard products, we offer flexible supply ranging from small-lot prototyping and evaluation to small- and medium-scale production, and even large-volume production according to your required quantities. 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 power supplies.
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 protection/overvoltage protection/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 based on the requirements of EU Regulation (EU) 2019/1782 and DOE 10 CFR Part 429/430.
4) EMC (Emissions)
Emissions compliant with FCC Part 15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity
EN55035/BS EN 55035 compliant, 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 (adjustable 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 as an embedded power supply 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 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) for selection, taking into account disturbances such as ESD, EFT, and surge
- When evaluating adoption including equipment operating conditions such as altitude and SEMI F47
Applications
Widely applicable as an embedded power supply for industrial equipment.
- Industrial equipment
- Control equipment
- Information and communication equipment
- Peripheral devices, etc.
