Certificate of Non-Use for RoHS (10 Substances)
The UNOWT 30W Series is an open-frame switching power supply for industrial equipment (30W class, standard product). It features a compact board size of 2 inch x 4.1 inch, complies with the safety standard 62368-1, and conforms to PSE Appendix 8 (100V standard). It is available in 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. 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 onboard trimmer potentiometer, the output voltage can be adjusted within a range of +/-10%.
| UNIFIVEReasons Unifive is chosen: As a power supply manufacturer with over 35 years of experience in power supply development, we provide comprehensive support from specification review with mass production adoption in mind, to certification acquisition, mass production launch, and post-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 manufacturing. We also support semi-custom solutions and assist with power supply selection from the specification review stage toward mass production adoption. |
Enclosure Options (3 Types)
You can select the enclosure specification based on the suffix code of the model number. The electrical specifications are the same.
| 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 code indicating a UNIFIVE development product + series code + input voltage + output power + function code".
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 fine adjustment to account for voltage drop on the load side and final tuning in the actual equipment, expanding the range in which the standard product can be used without modification.
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 actual operating conditions, please contact our sales representative.
3) Compact 2-inch x 4.1-inch Board
The board dimensions are 105.0 x 50.0mm (4.13 x 1.97 inches). 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 95.0 x 40.0mm. As a 30W-class control power supply, it is designed for easy installation even in the 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
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 requirements in secondary-side circuit design.
6) Equipped with 4 Protection Circuits and Up to 5-Year Warranty
In addition to short-circuit protection (SCP), overvoltage protection (OVP), and overcurrent protection (OCP), it is equipped with four types of protection circuits, including overtemperature protection (OTP). It also supports a warranty of up to 5 years, making it easy to establish maintenance plans for industrial equipment that is intended for long-term operation. For details regarding warranty terms, please contact our sales representative.
