Certificate of Non-use of RoHS (10 substances)
The UNOPT 75W Series (UNOPT3075) is an open-frame built-in power supply (board-type power supply) designed for industrial equipment. Based on a compact 2"×5.9" board size, the series configuration facilitates power supply selection tailored to specific installation conditions.
In addition to protection circuits such as short-circuit, overvoltage, and overcurrent (with an optional overtemperature feature), this product is compliant with Energy Efficiency Level VI (ErP/DoE), emissions (FCC/EN(CISPR)/BS EN), and immunity standards (EN55035, EN61000-4-x), allowing confirmation of design requirements based on specifications for mass production.
| Why Unifive is chosen: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification examination to certification acquisition, mass production start-up, and post-production follow-up with a view to mass production adoption. Based on standard products, we offer flexible supply tailored to production scales from small lots for prototyping and evaluation to medium, small, and large-scale production. We can also handle semi-customizations and support power supply selection from the specification examination stage for mass production adoption. |
Main Features
1) Standard Series with a Compact 2"×5.9" Board (Chassis/Cover Options Available)
In addition to the standard board (UNOPT3075), configurations with a chassis (UNBPT3075) and chassis + cover (UNSPT3075) are available, making it easy to choose 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 (model-specific conditions apply, please inquire). Equipped with protection circuits for short-circuit, overvoltage, and overcurrent protection. Overtemperature protection is optional.
3) High Efficiency Design (Energy Efficiency Level VI)
Compliant with Energy Efficiency Level VI (ErP/DoE), allowing selection based on EU regulation (EU) 2019/1782 and DOE 10 CFR part 429/430 requirements.
4) EMC (Emission)
Emissions comply with FCC Part15-B, EN(CISPR)55032-B, and BS EN 55032.
5) Immunity (Resistance)
Compliant with EN55035 and BS EN 55035, with resistance items specified under EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Specifications Supporting Industrial Equipment Requirements (PFC/Voltage Adjustment/Altitude/SEMI F47, etc.)
Includes PFC (power factor), inrush current, adjustable output voltage range, maximum operating altitude of 5,000m, OVC III (2,000m), SEMI F47 (with input condition notes), consideration for dust-prone environments (documented in specifications), and a 5-year warranty.
