UNOPT 100W Series (UNOPT3100) is an open frame power supply (board type) designed for integration into industrial equipment. Its compact 2.4"×6.1" board size allows for easy power selection based on mounting conditions.
Equipped with protection circuits for short-circuit/overvoltage/overcurrent, the specifications are designed to meet mass production power requirements such as Energy Efficiency Level VI (ErP/DoE), emissions (FCC/EN(CISPR)/BS EN), and immunity (EN55035, EN61000-4-x). It also supports requirements such as PFC, inrush current, voltage adjustment, operating altitude (up to 5,000m), and SEMI F47, making it ideal for organizing selection conditions.
| Why Unifive is chosen: With over 35 years of experience in power supply development, Unifive supports the entire process from specifications and certification planning for mass production adoption, through production ramp-up, to after-sales support. Based on standard models, we provide flexible supply from small-lot prototyping and evaluation to medium and large-lot production according to quantity needs. We also support semi-custom solutions, assisting in power selection from the specification planning stage for mass production adoption. |
Key Features
1) Standard Compact 2.4"×6.1" Series (Chassis/Cover Options Available)
In addition to the standard board (UNOPT3100), variants with chassis (UNBPT3100) and with chassis + cover (UNSPT3100) are available to suit mounting and protection requirements.
2) Technical Standards and Protection Circuits
Compliant with IEC/EN 62368-1 (BS EN 62368-1) standards and supports 100V–240V standards. Includes protection circuits for short circuit / overvoltage / overcurrent.
3) High Efficiency Design (Energy Efficiency Level VI)
Supports Energy Efficiency Level VI (ErP/DoE), enabling selection in accordance with Commission Regulation (EU) 2019/1782 and DOE 10 CFR parts 429 and 430.
4) EMC (Emissions)
Compliant with FCC Part15-B / EN(CISPR)55032-B / BS EN 55032 standards.
5) Immunity (Tolerance)
Compliant with EN55035 / BS EN 55035 and includes immunity items from EN61000-4-2 / -3 / -4 / -5 / -6 / -8 / -11.
6) Specifications That Aid Organization of Adoption Requirements for Industrial Equipment (PFC / Inrush Current / Voltage Adjustment / Altitude / SEMI F47 etc.)
Specifications include PFC (power factor), inrush current, output voltage setting and adjustable range, operating altitude (up to 5,000m), OVC III (2000m), and SEMI F47 (effective above 200V input)—ideal for organizing requirements according to equipment conditions. Remote ON/OFF (-CR compatible models) are also available.
Use Cases Where Adoption is Effective
