UxOWT 150W Series is an open-frame switching power supply for industrial equipment (150W class, standard Products). The board size is a compact 3 inch x 6.3 inch design, intended for internal installation in equipment. Four models are available: DC12.0V/24.0V/36.0V/48.0V.

The key feature is that three safety standards can be supported on the same board platform. By selecting the "x" in the model name, you can choose from medical equipment (60601-1), household appliances (61558-1/60335-1), or information and communication/AV equipment (62368-1/60065-1/60950-1). The same power supply design can be deployed across multiple Products lines with different applications.

Model Number System

The second character "x" in the model number indicates the applicable safety standard. Please select according to the field of your equipment.

Example: The 12.0V model for medical equipment is "UMOWT1150-120125SA".

Key Features

1) Supports three fields - medical, home appliances, and information and communications - with a single board

You can select only the required safety standard while keeping the same board size, mounting hole positions, and connector layout. For manufacturers developing Products across multiple fields, it is possible to horizontally expand into products with different regulatory requirements while standardizing mechanical and wiring design. This enables reuse of design assets and reduces the number of components.

2) 3-inch x 6.3-inch Compact Board

The board dimensions are 159.96 x 75.0 mm (6.3 x 2.95 inches). Component height is 34.0 mm or less from the top side of the board and 3.0 mm or less from the bottom side. There are four mounting holes (φ3.50 mm), with a mounting pitch of 149.96 x 65.0 mm. As a compact 150 W-class unit, it is easy to integrate into equipment with limited internal space.

3) Specifications Assuming Installation Environments for Industrial Equipment

The operating temperature range is 0~50°C, providing more margin on the high-temperature side compared to typical AC/DC Power Adapter (0~40°C). The overvoltage category supports OVC III (altitude 2,000 m), and the maximum operating altitude is up to 5,000 m. In addition, it complies with the dust-proof requirements of PSE Appendix 8. It is suitable for industrial equipment installed in harsh environments and for devices intended for use at high altitudes.

4) SEMI F47 Compliance

Compliant with SEMI F47, a voltage sag (momentary voltage drop) immunity standard for semiconductor manufacturing equipment. Even if a momentary voltage drop occurs, operation can continue, helping to reduce production losses caused by equipment stoppages.

Note:Compliance with SEMI F47 is applicable under conditions where the input voltage exceeds AC200V. For details on applicable conditions, please contact our sales representative.

5) Equipped with Brown-in/Brown-out Protection

In addition to short circuit protection (SCP), overvoltage protection (OVP), and overcurrent protection (OCP), it is equipped with brown-in/brown-out protection. It prevents operation when the input voltage falls below the specified level and starts up stably after the voltage recovers. Even in environments with unstable power quality, it helps avoid operation in undefined states.

6) Maximum efficiency 88% - Up to 5-year warranty

It features a high-efficiency design with a maximum efficiency of 88%. It also comes with a warranty of up to 5 years. For industrial equipment intended for long-term operation, it can be adopted under conditions that make maintenance planning easier. Please contact our sales team for details of the warranty terms.

List of Representative Models

Output voltage accuracy: ±5% / Output ports: CN101(+V), CN102(-V)
For the "x" in the model number, one of M/H/N will be entered according to the above model numbering system.
Measurement conditions: Measurements are performed using an oscilloscope with a bandwidth of 20MHz. The output is bypassed at the connector with a 0.1μF ceramic disc capacitor and a 10μF low-ESR electrolytic capacitor to simulate the system load.

Main Applications

As a power supply built into equipment, it can be used widely across various fields. Depending on the model number, you can select the applicable safety standards, making it suitable for the following applications.

• Built-in power supplies for industrial and manufacturing equipment
• Semiconductor manufacturing equipment and peripheral devices
• Medical devices and clinical laboratory equipment (applications requiring 60601-1)
• Commercial home appliances and kitchen equipment (applications requiring 60335-1)
• Built-in power supplies for information and communication equipment and AV equipment
• Measuring instruments and analytical equipment
• Equipment intended for use at high altitudes

If you are looking for a power supply to be connected externally to equipment, please see our AC/DC Power Adapter series.

Semi-Custom Support

Output voltage and output current, connector type and position, harness additions, and more can be semi-customized to match your equipment. Because we use standard products as a base, specifications can be optimized while reducing development time and initial costs compared to full custom solutions.

For specification confirmation, quotations, or sample requests, please feel free to contact our sales team. You can also view customization examples on the Customization Case Studies page.
