RoHS (10 Substances) Non-Use Certificate
The UNOWT 50W Series is an open-frame switching power supply for industrial equipment (50W class, standard Products). The board size features a compact design of 2 inch x 5.2 inch, complies with the safety standard 62368-1, and conforms to PSE Appendix Table 8 (100V standard). It is available in 6 models ranging from DC5.0V~48.0V.
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 electric shock and contact protection, only the enclosure specification can be changed later. In addition, by using the on-board trimmer potentiometer, the output voltage can be adjusted within a range of ±10%.
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of power development experience, we provide comprehensive support from specification review for mass production adoption to certification acquisition, mass production launch, and post-mass production follow-up. Based on standard products, we offer flexible supply according to production volume, from small-lot prototyping and evaluation to small- and medium-scale production, and even large-volume production. We also support semi-custom solutions and assist with power supply selection for mass production adoption from the specification review stage. |
Enclosure Options (3 Types)
The enclosure specifications can be selected according to the suffix code of the model number. The electrical specifications are common.
| Series Name | Code | Specifications |
|---|---|---|
| UNOWT1050 | O | Standard version (board only) |
| UNBWT1050 | B | With chassis |
| UNSWT1050 | S | With chassis + cover |
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 resistor (VR21), the output voltage can be adjusted within ±10% of the rated value. This allows fine-tuning to account for voltage drops on the load side and final adjustments on the actual device, expanding the range of applications where a standard model can be used as-is.
2) Operating temperature -10~+70°C, supports installation in 6 orientations
The operating temperature range is -10~+70°C, and the storage temperature range is -30~+75°C. The mounting orientation supports 6 positions (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~+50°C, 75% at +60°C, and 50% 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 department.
3) 2-inch x 5.2-inch Compact Board
The board dimensions are 132.0 x 50.0 mm (5.20 x 1.97 inches). The component height is 22.4 mm or less from the top side of the board and 3.0 mm or less from the bottom side. The mounting hole diameter is φ3.50 mm, and the mounting pitch is 122.0 x 40.0 mm. As a 50 W class control power supply, it is designed for easy installation in limited internal equipment spaces.
4) Specifications for installation environments of industrial equipment
The overvoltage category supports OVC III (altitude 2,000 m), and the operating altitude is up to 5,000 m. It is also compliant with the dust protection requirements of PSE Appendix 8.
5) Energy Efficiency Level VI Compliant and LPS Support
Energy Efficiency Level VI (ErP/DoE) compliant, 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 requirements in secondary-side circuit design.
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), Over Voltage Protection (OVP), and Over Current Protection (OCP). In addition, it comes with a warranty of up to 5 years, making it suitable for industrial equipment that requires long-term operation and easier maintenance planning. For details regarding warranty terms and conditions, please contact our sales department.
