Certificate of Non-Use of RoHS (10 Substances)
The UNOWT 30W Series is an open-frame switching power supply for industrial equipment (30W class, standard Products). The board size features a compact design of 2 inches x 4.1 inches, complies with the safety standard 62368-1, and conforms to PSE Appendix Table 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. Depending on the internal mounting method of the equipment and requirements for electric shock and contact protection, it is possible to change only the enclosure specification later. In addition, by using the built-in trimmer potentiometer on the board, the output voltage can be adjusted within a range of ±10%.
| UNIFIVEReasons to Choose: As a power supply manufacturer with over 35 years of power supply development experience, we provide comprehensive support from specification planning with mass production adoption in mind, 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-lot production. We also support semi-custom solutions and assist with power supply selection aimed at mass production adoption from the specification planning stage. |
Enclosure Options (3 Types)
You can select the enclosure specification by the suffix code of the model number. Electrical specifications are common.
| Series Name | Code | Specifications |
|---|---|---|
| UNOWT1030 | O | Standard version (board only) |
| UNBWT1030 | B | With chassis |
| UNSWT1030 | 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%
By using the semi-fixed resistor (VR21) on the board, 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 device, expanding the range in which the standard product can be adopted as is.
2) Operating temperature -10~+70°C, supports 6 mounting directions
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, 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). For derating curves based on your actual operating conditions, please contact our sales department.
3) Compact 2-inch x 4.1-inch board
The board dimensions are 105.0x50.0mm (4.13x1.97 inches). The component height is 22.4mm or less from the top side of the board and 3.0mm or less from the bottom side. The mounting hole diameter is φ3.50mm, and the mounting pitch is 95.0x40.0mm. As a 30W-class control power supply, it is designed for easy installation in limited space inside equipment.
4) Specifications Assuming Installation Environment of Industrial Equipment
The overvoltage category supports OVC III (altitude 2,000m), with an operating altitude up to 5,000m. In addition, it complies with the dust-proof requirements of PSE Appendix 8.
5) Compliant with Energy Efficiency Level VI and Supports LPS
Energy Efficiency Level VI (ErP/DoE) compliant, meeting 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 satisfy secondary-side circuit design requirements.
6) Equipped with 4 Protection Circuits and Up to 5-Year Warranty
In addition to Short Circuit Protection (SCP), Over Voltage Protection (OVP), and Over Current Protection (OCP), it is equipped with four types of protection circuits, including Over Temperature Protection (OTP). It also 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 about warranty terms, please contact our sales representatives.
