UNOWT 15W Series is an open-frame switching power supply (15W class, standard Products) for industrial equipment. The board size features a compact design of 2 inches x 3.4 inches, complies with the safety standard 62368-1, and conforms to PSE Appendix 8 (100V standard). Five models are available with outputs ranging from DC3.3V to 24.0V.

Based on the same board, you can choose from three types: board only, with chassis, or with chassis + cover. According to the internal mounting method of the equipment and requirements for electric shock and contact prevention, only the enclosure specification can be changed later. In addition, a built-in trimmer resistor on the board allows output voltage adjustment within a range of +/-10%.

Enclosure Options (3 Types)

You can select the enclosure specification by the suffix code of the model number. Electrical specifications are common.

The model number consists of "a symbol indicating a UNIFIVE developed product + series code + input voltage + output power + function symbol".

Key Features

1) Output voltage adjustable within ±10%

Using the on-board trimmer potentiometer (VR1), the output voltage can be adjusted within ±10% of the rated value. This allows for fine adjustment to account for voltage drops on the load side and final tuning on the actual device, expanding the range in which the standard product can be adopted.

2) Operating temperature -10 to +70°C, supports 6 mounting directions

The operating temperature range is -10 to +70°C, and the storage temperature range is -30 to +75°C. The mounting direction supports 6 orientations (A to F), including the standard position, allowing flexible placement according to the internal layout of the equipment. The load factor under natural convection is 100% at -10 to +50°C, 70% at +60°C, and 40% at +70°C.

Note: The allowable load factor varies depending on the combination of ambient temperature, mounting orientation, and cooling conditions (natural convection/forced air cooling). For derating curves based on actual operating conditions, please contact our sales representative.

3) 2 inch x 3.4 inch compact board

The board dimensions are 87.5x50.0mm (3.44x1.97 inches), with a component height of 17.4mm or less from the top side and 3.0mm or less from the bottom side. There are two mounting holes (phi 3.50mm). As a 15W class control power supply, it is designed for easy installation in limited space inside equipment.

4) Specifications for Industrial Equipment Installation Environments

The overvoltage category supports OVC III (altitude 2,000m), and the operating altitude is up to 5,000m. In addition, it complies with the dust-proof requirements of PSE Appendix 8.

5) Energy Efficiency Level VI Compliant / LPS Support

Energy Efficiency Level VI (ErP/DoE) compliant, and meets EU Commission Regulation 2019/1782 and US DOE 10 CFR Part 429 and 430. Also supports LPS (Limited Power Source), making it easier to satisfy requirements in secondary-side circuit design.

6) Equipped with Three Protection Circuits, Up to 5-Year Warranty

It is equipped with three types of protection circuits: short-circuit protection (SCP), overvoltage protection (OVP), and overcurrent protection (OCP). In addition, it comes with a warranty of up to 5 years, making it easy to adopt under conditions that facilitate maintenance planning for industrial equipment intended for long-term operation. For details of the warranty terms, please contact our sales team.

List of Representative Models

Output port: CN2 / The output voltage can be adjusted within a range of ±10% using a semi-fixed resistor.
The above are model numbers without chassis (board only). With chassis: UNBWT1015, with chassis + cover: UNSWT1015.
Measurement conditions: Measurements are performed using an oscilloscope with a bandwidth of 100MHz. The output is bypassed at the connector with a 0.1μF ceramic disc capacitor and a 100μF low-ESR electrolytic capacitor to simulate system load. The cable length during ripple measurement is 150mm.

Common Specifications

Note: The acquired safety standards vary depending on the model. For certification status of specific models, please contact our sales department.

External Dimensions and Connector Specifications

Dimensional tolerance: ±0.5mm. For dimensions and detailed drawings of the chassis model (UNBWT1015), please contact our sales department.

Main Applications

This product can be widely used as a control power supply built into industrial equipment. Leveraging its 15W class rating, compact board design, and wide operating temperature range, it is suitable for the following applications.

• Power supply for control circuits in industrial and manufacturing equipment
• Semiconductor manufacturing equipment and peripheral devices
• Power supply for sensors and measurement units
• Installation inside control panels and distribution boards
• Auxiliary power supply for FA equipment and transport systems
• Equipment used in high-altitude or environments with large temperature fluctuations

If a higher output is required, we can offer open-frame power supplies with higher wattage classes.

Semi-Custom Support

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

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