Certificate of Non-use of RoHS (10 Substances)
The UNOPT 75W Series (UNOPT3075) is an open frame power supply (board-type power supply) designed for integration into industrial equipment. With a compact 2"×5.9" board size, this series configuration facilitates power supply selection based on mounting requirements.
In addition to protection circuits for short-circuit, overvoltage, and overcurrent (plus overtemperature as an option), this series supports Energy Efficiency Level VI (ErP/DoE), emission (FCC/EN(CISPR)/BS EN), and immunity (EN55035, EN61000-4-x), allowing power requirements for mass-production design to be verified according to specifications.
| Why UNIFIVE is Chosen: As a power supply manufacturer with over 35 years of development experience, we provide consistent support from specification reviews with a view toward mass production, to certification acquisition, production setup, and post-mass production follow-up. Based on standard products, we offer flexible supply from small-lot prototypes/evaluation, to small-to-medium volume production, and up to large-lot production. We also support semi-customization and assist with power supply selection from the specification planning stage to ensure mass production readiness. |
Key Features
1) Compact 2"×5.9" Standard Series (Chassis/Cover Options Available)
In addition to the standard board (UNOPT3075), configurations are available with chassis (UNBPT3075) and chassis plus cover (UNSPT3075), allowing selection based on mounting and protection requirements. As a market standard product, it is also ideal for replacing existing units.
2) Technical Standards & Protection Circuits
Compliant with IEC/EN 62368-1 (BS EN 62368-1) technical standards (conditions may vary by model; please inquire). Equipped with protection circuits for short-circuit, overvoltage, and overcurrent; overtemperature protection is optional.
3) High-Efficiency Design (Energy Efficiency Level VI)
Compliant with Energy Efficiency Level VI (ErP/DoE), supporting selection in accordance with EU Regulation (EU) 2019/1782 and DOE 10 CFR part 429/430 requirements.
4) EMC (Emission)
Emission is compliant with FCC Part15-B, EN(CISPR)55032-B, and BS EN 55032.
5) Immunity (Noise Resistance)
Compliant with EN55035 and BS EN 55035, and meets resistance levels for EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Specifications Supporting Industrial Equipment Requirements (PFC/Voltage Adjustment/Altitude/SEMI F47 etc.)
Features include PFC (power factor correction), inrush current, output voltage adjustment (with adjustable range noted), operating altitude up to 5000m, OVC III (2000m), SEMI F47 (with notes on input conditions), design considerations for dust-prone environments (noted in specifications), and a 5-year warranty.
Effective Use Cases
