Certificate of Non-use of RoHS (10 Substances)
The UNOPT 50W Series is an open-frame power supply (board power supply) designed for industrial equipment. With a compact 2"×5.2" class board size, it is structured as a market-standard series that facilitates component selection considering implementation requirements.
In addition to protection circuits (short-circuit/over-voltage/over-current), the specifications confirm compliance with power supply requirements for mass production design, such as energy efficiency (Energy Efficiency Level VI), emissions (FCC/EN(CISPR)/BS EN), and immunity (EN55035, EN61000-4-x).
| Reasons to choose UNIFIVE: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification evaluation through to certification, production launch, and post-production follow-up. Based on standard models, we flexibly supply in line with production volume — from small-lot prototyping and testing, to medium- and large-scale production. We also support semi-customization from the specification review stage to help select power supplies for mass production adoption. |
Key Features
1) Standard compact 2"×5.2" series (chassis/cover options available)
In addition to standard boards, configurations such as with chassis or with chassis and cover can be selected to meet implementation and protection requirements. Ideal for replacing market products.
2) Technical standards and protection circuits
Compliant with technical standards 62368-1 and 100V–240V (check model-specific conditions). Includes protection circuits for short-circuit, over-voltage, and over-current, with optional over-temperature protection.
3) Efficiency
Compliant with Energy Efficiency Level VI (ErP/DoE). Typical efficiency is listed in the specifications of representative models and may vary by model.
4) EMC (emissions)
Compliant with FCC Part15-B, EN(CISPR)55032-B, and BS EN 55032.
5) Immunity (resistance)
Compliant with EN55035 and BS EN 55035, and includes resistance items per EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Specifications for installation environments and operational requirements (PFC/altitude/voltage adjustment, etc.)
Includes PFC (power factor), output voltage adjustment (variable range depends on model), SEMI F47 (notes on input conditions), OVC III (2000m), max operating altitude of 5,000m, and 5-year warranty.
Recommended Use Cases
- When you want to adopt compact 2"×5.2" class board-type power supplies for internal use in industrial equipment
- When you want to select configurations such as with chassis or chassis and cover to meet implementation/protection conditions
- When selecting power supplies for mass production assuming compliance with efficiency requirements (Energy Efficiency Level VI)
- When selecting power supplies to comply with emission requirements (FCC/EN(CISPR)/BS EN) in EMC design
- When selecting power supplies considering resistance requirements (EN61000-4-x) to account for ESD, EFT, surge, and other disturbances
- When evaluating suitability for adoption along with equipment operational requirements including installation altitude and input conditions (such as SEMI F47)
