RoHS (10 Substances) Non-Use Certificate
The UNOPT 50W Series is an open-frame power supply (board-mounted power supply) designed for embedded use in industrial equipment. Based on a compact 2"x5.2" board size class, it is configured as a market-standard series that facilitates power supply selection in consideration of mounting conditions.
In addition to protection circuits (short circuit/overvoltage/overcurrent), specifications allow you to confirm power supply requirements that must be organized for mass production design, such as efficiency requirements (Energy Efficiency Level VI), 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 consistent support from specification review assuming mass production adoption, to certification acquisition, mass 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 large-scale 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) Compact 2"x5.2" standard series (chassis/cover options available)
In addition to the standard board type, configurations with chassis or chassis plus cover are available to meet mounting and protection requirements. Ideal for replacement of existing market products.
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, with overtemperature protection optional.
3) Efficiency
Energy Efficiency Level VI (ErP/DoE) compliant. Representative model specification tables include efficiency (Typical) values, which vary by model and conditions.
4) EMC (Emissions)
Compliant with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032 for emissions.
5) Immunity
EN55035/BS EN 55035 compliant, with immunity items including EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Specifications useful for organizing installation environment and operational requirements (PFC/altitude/voltage adjustment, etc.)
Includes PFC (power factor indicated), output voltage adjustment (range varies by model), SEMI F47 (with notes on applicable input conditions), OVC III (2000m), operating altitude up to 5,000m, and a 5-year warranty.
Effective Use Cases
- When adopting a compact 2"x5.2" class board power supply as an embedded power supply for industrial equipment
- When selecting configurations such as chassis or 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 immunity requirements (EN61000-4-x) in view of disturbances such as ESD, EFT, and surge
- When evaluating adoption based on equipment operating conditions, including installation altitude and input conditions (SEMI F47, etc.)
