The UOP 90W Series (UOP390) is an open-frame power supply (board-type power supply) suitable for embedded equipment applications. As a built-in AC-DC power supply in the 90W class, it has a configuration that facilitates power supply selection based on mounting conditions.
Equipped with protection circuits for short-circuit/overvoltage/overcurrent/overtemperature, it can also be used to verify requirements based on emission (CE CISPR 32 EN55032 / FCC Part15 Class B) and immunity standards (EN55024).
| Reasons to choose Unifive: As a power supply manufacturer with over 35 years of development experience, we provide consistent support throughout the entire process from specification review, certification acquisition, mass production launch, to post-production follow-up, with mass production adoption in mind. Starting from standard products, we can flexibly supply in quantities ranging from small-lot prototyping and evaluation to mid- and large-scale production. Semi-customization is also available, and we support power selection toward mass production adoption starting from the specification review stage. |
