## Long description

The BREVE AUTO OIEA 15 is a professional single-phase autotransformer engineered for precise voltage regulation in demanding electrical environments. This device allows for a smooth adjustment of output voltage from 0V to 260V when supplied with a standard 230V input. Built with high-quality components, it provides reliable performance for industrial, laboratory, and testing applications where consistent and adjustable power supply is essential.
Advantages
The primary advantage of this autotransformer is its ability to provide a continuously variable output voltage, which is critical for testing electronic equipment or controlling power-dependent processes. Its robust construction ensures long-term durability and stable operation even under continuous load. The device is designed to maintain high efficiency and thermal stability, making it a dependable solution for professionals who require accurate voltage control without the complexity of more elaborate power systems.
Suitable for
Laboratory testing and research
Industrial voltage regulation
Powering specialized electrical equipment
Educational demonstrations in physics and electronics
Testing of household appliances and industrial machinery
When it may not be suitable
This autotransformer does not provide galvanic isolation between the input and output circuits, meaning it is not suitable for applications where safety requires electrical separation from the mains. It is also not intended for high-frequency power conversion or for use in environments with extreme moisture or corrosive gases.
Key specifications
Input voltage: 230V AC
Output voltage range: 0-260V AC
Rated current: 12A
Phase: Single-phase
Design: Open-type autotransformer
How to use
To use the BREVE AUTO OIEA 15, connect the input terminals to a stable 230V power source. Ensure that the load is connected to the output terminals according to the specified current limits. Use the manual control knob to gradually adjust the output voltage to the desired level. Always monitor the output voltage with a multimeter during the adjustment process to ensure it matches the requirements of your connected equipment.
What to consider before purchase
Verify that the 12A rated current is sufficient for your specific load requirements.
Ensure the installation environment is dry and well-ventilated.
Confirm that your application does not require galvanic isolation.
Check the physical dimensions to ensure it fits within your workspace or enclosure.
Usage recommendations: Always start with the voltage control set to zero before powering on the device. Gradually increase the voltage to the required level and ensure that the total current draw does not exceed the 12A limit to prevent overheating or damage to the unit.
