UMOYT3048 P Series Peak 1-Second Compatible Product
|
UMOYT3048 P is a 48W-class embedded open-frame power supply primarily designed for medical equipment applications compliant with IEC 60601-1. With an insulation design supporting 2×MOPP, it ensures high safety levels for medical devices with patient contact and enables power supply designs that meet stringent medical safety requirements. In addition to its rated output, it features a peak power function capable of delivering up to 175% of peak power for a specified duration, making it suitable for medical applications involving motor drives, actuator startup, and inrush loads. Furthermore, its high-efficiency design achieves up to 87.77% efficiency, balancing energy savings with stable power delivery. It includes protection against short circuit, overvoltage, overcurrent, and overtemperature, and complies with various EMC and immunity standards, including IEC 60601-1-2. The 2×4-inch board size, while supporting peak power capability, is configured for integration into medical equipment, making it an ideal power solution for diagnostic devices, therapeutic equipment, and peripheral medical systems that require both instantaneous high load handling and high safety standards.

Contact form
The UxOYT 48W P Series (UxOYT3048P) is an open-frame power supply (PCB power supply) for medical equipment designed for Medical/Home/I.C.T. applications. With a space-saving 2"x4" PCB size, it is well-suited for built-in equipment applications, making power selection easier based on actual mounting conditions.
This series is designed with consideration for peak load (1 second), making it useful for organizing power requirements in equipment with load fluctuations. In addition to short-circuit, overvoltage, and overcurrent protection, overtemperature protection (optional) is also available.
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review for mass production adoption to certification acquisition, mass production launch, and post-production follow-up. Based on standard products, we offer flexible supply from small-lot prototyping and evaluation to small- and medium-scale production, as well as large-volume production. We also support semi-custom solutions and assist with power selection from the specification review stage toward mass production adoption. |
Key Features
1) Open-frame power supply (PCB power supply) for medical equipment
An open-frame power supply for medical equipment designed for built-in equipment applications. The 2"x4" PCB size space-saving design allows easy adoption even under limited mounting conditions inside enclosures.
2) Technical standards and protection circuits
Applicable safety standards differ depending on the model classification (M/H/N). Equipped with short-circuit, overvoltage, and overcurrent protection, with overtemperature protection available as an option.
3) Supports peak load (1 second)
Equipped with a peak load function supporting up to 175% of the rated output (peak time: 1 second, duty: 0.2). Facilitates requirement organization during design and evaluation for startup and load fluctuations.
4) Efficiency
Up to 85.00%.
5) EMC (Emission)
Compliant with FCC Part15-B/Part18-B, EN(CISPR)55032-B/55011-B/55014-B, and BS EN 55032/55011/55014-1. Please refer to "Standards and Compliance" for details.
6) Immunity
Based on requirements such as EN55035/BS EN 55035, EN60601-1-2, and EN55014-2, immunity items per EN61000-4-2/-3/-4/-5/-6/-8/-11 are specified. Please refer to "Standards and Compliance" for details.
Effective Use Cases
- When integrating a 48W-class open-frame power supply (PCB power supply) for medical equipment as a built-in power supply
