Control and signalling transformers are used for many types of industrial applications. For example, they power relays, indicators, push-buttons and other control devices in industrial automation systems. In a production line, these transformers supply the voltage required by sensors and actuators. They are also used in electrical switchboards to power control and signalling circuits, including lighting systems, alarms, etc. These transformers are essential for various security and intelligent building management systems, such as heating, ventilation and air conditioning (HVAC) systems and access systems. In the transport sector (trains, metros, trams), they power information panels, signalling systems and control devices.

In our online shop, One-Elec, you'll find control and signalling transformers of different power ratings, voltages and mounting forms. So it's important to understand the different characteristics so you can choose the right one for your needs.
Here are some important characteristics to consider:

  • Rated power (VA)

The power rating indicates the transformer's ability to deliver a certain output power. Make sure it corresponds to the specific needs of your control and signalling devices. To calculate it correctly, add up the power required from each device to determine the total power required.

  • Input and output voltage

Check that the transformer's input and output voltages match those of your equipment. For example, if you need 24 V output, choose a transformer with this voltage.

  • Galvanic isolation

Make sure that the transformer provides galvanic isolation between the input and output circuits. This protects your equipment from interference and ensures safety, particularly in industrial environments where high voltages may be present.

  • Form factor and mounting

Select a transformer to suit the space available in your electrical cabinet. Some models are designed for DIN rail mounting, ideal for modular installations, while others can be mounted directly on a flat surface for specific configurations.

  • Ambient temperature and insulation class

Check the operating temperature range of the transformer. Also choose an appropriate insulation class (for example, class B for temperatures up to 130°C, class F up to 155°C, or class H up to 180°C) depending on the environment.

  • Reliability and certification

Opt for quality transformers that comply with safety and performance standards. Look for certifications such as CE (Conformité Européenne), UL (Underwriters Laboratories) and RoHS (Restriction of Hazardous Substances) to guarantee compliance and safety.
