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). Five models are available with outputs ranging from DC 3.3V to 24.0V.

Based on the same board design, 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 electric shock and contact prevention, only the enclosure specification can be changed later. In addition, a trimmer potentiometer on the board allows output voltage adjustment within a range of ±10%.

Enclosure Options (3 Types)

The enclosure specification can be selected by the suffix code of the model number. The electrical specifications are the same.

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 means of 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 drops on the load side and final tuning on the actual equipment, expanding the range in which the standard product can be used without modification.

2) Operating temperature -10~+70C - Supports installation in 6 orientations

The operating temperature ranges widely from -10~+70C, and the storage temperature is -30~+75C. It supports 6 mounting orientations (A~F), including the standard position, allowing placement according to the internal layout of the equipment. Under natural convection, the load factor is 100% at -10~+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). For derating curves based on your actual operating conditions, please contact our sales representative.

3) Compact 2-inch x 3-inch Board

The board dimensions are 73.5 x 50.0 mm (2.89 x 1.97 inches), with a component height of 17.4 mm or less from the top surface and 3.0 mm or less from the bottom surface. There are two mounting holes (φ3.50 mm). As a 10 W 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. It also complies with the dust protection requirements of PSE Appendix 8.

5) Compliant with Energy Efficiency Level VI and Supports LPS

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

6) Equipped with 3 types of protection circuits and up to a 5-year warranty

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 suitable for maintenance planning in industrial equipment intended for long-term operation. For details regarding warranty terms, please contact our sales department.

List of Representative Models

Output port: CN2 / The output voltage can be adjusted within a ±10% range using a trimmer potentiometer.
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 disk 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 department regarding the certification status of individual 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

It can be widely used as a control power supply built into industrial equipment. Leveraging its 10W class output, 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
• Built into control panels and distribution boards
• Auxiliary power supply for FA equipment and transport systems
• Equipment used in high-altitude areas 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, harness additions, and more can be semi-customized to match your equipment. Because the design 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 requests, please feel free to contact our sales team. You can view customization examples on the Customization Case Studies page.
