UNOWT 50W Series is an open-frame power supply (board-mounted power supply) for industrial equipment. It is configured as a standard series with compact 2"×5.2" form factor, making it easy to select based on implementation conditions.
Equipped with protection circuits (short-circuit/over-voltage/over-current), it meets power requirements for mass production including Energy Efficiency Level VI (ErP/DoE), emission standards (FCC/EN(CISPR)/BS EN), and immunity standards (EN55035, EN61000-4-x), all verifiable by specifications.
| UNIFIVE With over 35 years of experience in power supply development, we provide full support from spec evaluation, certification acquisition, mass production launch to post-mass-production support. Based on standard products, we can flexibly supply from small-lot prototyping and evaluation to medium-scale and large-scale production. Semi-customization is available to support power supply selection from the specification review stage for mass production use. |
Main Features
1) Market-standard compact 2"×5.2" series (configurable with chassis/cover/remote ON/OFF options)
In addition to the standard board, configurations can include chassis, chassis with cover, and remote ON/OFF based on mounting and operational needs. Ideal for replacing existing products.
2) Compliance with technical standards and protection circuits
Compliant with 62368-1 and 100V–240V standards (please inquire for conditions of each model). Equipped with short-circuit protection/over-voltage protection/over-current protection.
3) Efficiency
Supports Energy Efficiency Level VI (ErP/DoE) and can be selected based on the requirements of Commission Regulation (EU) 2019/1782 and DOE 10 CFR part 429 and 430.
4) EMC (Emission)
Compliant with FCC Part15-B/EN(CISPR)55032-B/BS EN 55032.
5) Immunity (Noise resistance)
Conforms to EN55035/BS EN 55035 with resistance tests for EN61000-4-2/-3/-4/-5/-6/-8/-11.
6) Derating based on mounting and cooling conditions (reference values)
Reference derating curves are available based on mounting orientations and ambient temperature. Conditions for forced air cooling (>15 CFM) and natural cooling are also provided, useful for heat and layout considerations in enclosures.
Effective Use Cases
- Want to adopt compact 2"×5.2" board power supply as a built-in power source for industrial equipment
- Want to choose configuration based on implementation and maintenance needs (chassis/cover, remote ON/OFF, etc.)
- Want to proceed with power supply selection for mass production with Energy Efficiency Level VI as a prerequisite
- Want to select a power supply based on emission standards (FCC/EN(CISPR)/BS EN) in EMC design
- Want to select based on immunity standards (EN61000-4-x) considering disturbances like ESD, EFT, and surge
- Want to evaluate applicability based on constraints like mounting orientation, cooling, and ambient temperature with reference to derating
- Want to organize selection conditions including installation environment (e.g., altitude, SEMI F47)
Applications and Use Cases
Widely applicable as a built-in power supply for industrial equipment.
- Industrial equipment
- Control devices
- Information and communication devices
- Peripheral devices, etc.
