Encased regulating autotransformers AUTO OIEA 15 230/0-260V 12A 19854-0031

Voltage regulation in installations and devices

Regulatory autotransformers from the OIEA series are reliable devices used for smooth output voltage adjustment. This specific model, designated 19854-0031, is designed for use in industrial and power installations where precise voltage control is crucial. Manufactured in accordance with EN61558-1 and EN61558-2-14 standards, it ensures safety and compliance with applicable regulations.

Characteristics and application

The OIEA 15 autotransformer allows voltage regulation in the range of 0 to 260V with a primary voltage of 230V. Designed to operate at a frequency of 50-300Hz, it performs perfectly in various applications. Its construction allows for panel mounting, and the IP00 protection class indicates no protection against the ingress of solids and water – therefore, it is recommended to use it in dry and clean environments. The output current of 12A makes it suitable for devices with medium power consumption.

Construction and parameters

The dimensions of the autotransformer (225 mm x 225 mm x 135 mm) and its weight (13.5 kg) should be taken into account when planning the installation. The open construction requires special care during installation and operation to avoid accidental contact with live parts. It is important to remember the maximum ambient temperature of 45°C. Thanks to its construction, this autotransformer is ideal for applications where precise voltage regulation is required without the need for traditional isolation transformers. This solution allows for reducing energy losses and improving system efficiency.
