RoHS (10 Substances) Non-Use Certificate
The UOB 12W Series (UOB310) is an open-frame power supply (PCB power supply) suitable for equipment integration applications. It is designed for use as a built-in power supply for I.C.T./AV equipment, making it easy to proceed with power supply selection based on the mounting conditions of the end device.
This is an AC-DC switching power supply. Power requirements in mass production design (protection, EMC, durability, etc.) can be verified based on the conditions specified in the datasheet. It is equipped with short-circuit, overvoltage, and overcurrent protection circuits, and supports design and evaluation in consideration of emission (CISPR 32/FCC Part15/BS EN) and immunity (EN55035) requirements.
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review assuming mass production adoption, to certification acquisition, mass production launch, and post-production follow-up. Based on standard products, we offer flexible supply options according to production volume, from small-lot prototyping and evaluation to small- and medium-scale production, as well as large-scale mass production. We also support semi-custom solutions and assist with power supply selection from the specification review stage for mass production adoption. |
