The UNOWT1010 Series is an open-frame switching power supply for industrial equipment (10W class, standard Products). The board size features a compact 2 inch x 3 inch design, complies with the safety standard 62368-1, and conforms to PSE Appendix 8 (100V standard). It is available in five models with outputs ranging from DC3.3V to 24.0V.

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

Enclosure Options (3 Types)

The enclosure specifications can be selected according to the suffix code of the model number. The electrical specifications are common.

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

Key Features

1) Output voltage adjustable within ±10%

By using the on-board trimmer resistor (VR21), 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 in the actual equipment, expanding the range in which the standard product can be adopted as-is.

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

The operating temperature range is -10 to +70°C, and the storage temperature range is -30 to +75°C. The mounting orientation supports 6 options (A-F), including the standard position, allowing flexible placement according to the internal layout of the equipment. Under natural convection, the load factor is 100% at -10 to +50°C, 70% at +60°C, and 20% 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). Please contact our sales team for derating curves based on your actual operating conditions.

3) 2-inch x 3-inch Compact PCB

The board dimensions are 73.5x50.0mm (2.89x1.97 inches), with a component height of 17.4mm or less from the top surface and 3.0mm or less from the bottom surface. There are two mounting holes (phi3.50mm). As a 10W-class control power supply, it has a form factor that allows easy installation even in limited internal spaces of equipment.

4) Specifications for industrial equipment installation environments

Supports OVC III (altitude 2,000 m), with an operating altitude up to 5,000 m. Also complies with the dust protection requirements of PSE Appendix 8.

5) Energy Efficiency Level VI Compliant and LPS Compatible

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

6) Equipped with 3 Types of Protection Circuits and Up to 5-Year Warranty

This product 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 incorporate into maintenance plans for industrial equipment intended for long-term operation. For details regarding warranty terms and conditions, please contact our sales department.

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: UNBWT1010; with chassis + cover: UNSWT1010.
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 details of individual models, please contact our sales department.

Overall Dimensions and Connector Specifications

Dimensional tolerance: +/-0.5mm. For dimensions and detailed drawings of the chassis version (UNBWT1010), please contact our sales department.

Main Applications

This power supply can be widely used as a control power source built into industrial equipment. Leveraging its 10W class rating, compact PCB 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 higher output is required, we can provide higher wattage open-frame power supplies.

Semi-Custom Support

Output voltage and current, connector type and position, chassis shape, and the addition of harnesses can be semi-customized to match your equipment. Since we base the design on standard products, 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 examples of customization on the Customization Case Studies page.
