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 Table 8 (100V standard). It offers five models ranging from DC3.3V~24.0V.

Based on the same PCB design, 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 protection, only the enclosure specification can be changed later. In addition, by using the on-board trimmer resistor, the output voltage can be adjusted within a range of ±10%.

Enclosure Options (3 Types)

You can select the enclosure specification according to the suffix code of the model number. The electrical specifications are the same for all types.

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%

With the on-board trimmer resistor (VR21), the output voltage can be adjusted within ±10% of the rated value. This allows fine adjustment to account for voltage drop on the load side and final tuning in the actual device, expanding the range in which the standard product can be used without modification.

2) Operating temperature -10 to +70C, supports installation in 6 orientations

The operating temperature range is -10 to +70C, and the storage temperature range is -30 to +75C. The mounting orientation supports 6 positions (A to 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 +50C, 70% at +60C, and 20% at +70C.

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 department for derating curves based on your actual operating conditions.

3) 2-inch x 3-inch Compact Board

The board dimensions are 73.5 x 50.0mm (2.89 x 1.97 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 10W-class control power supply, it features a form factor that can be easily installed 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. It also complies with the dustproof requirements of PSE Appendix Table 8.

5) Compliant with Energy Efficiency Level VI and LPS Support

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

6) Equipped with 3 Protection Circuits - 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 supports 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 ±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 taken 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. Please contact our sales representative for the certification status of specific models.

External 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

Widely used as a control power supply built into industrial equipment. Leveraging its 10W class output, 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
• Built-in 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 offer higher wattage open-frame power supplies.

Semi-Custom Support

Output voltage and output current, connector type and position, chassis shape, addition of harnesses, and more can be supported with semi-customization to match your equipment. Because it is based 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 inquiries, please feel free to contact our sales team. You can view examples of customization cases on the Customization Case Studies page.
