domeashop Transformers

Discover a selection of electrical transformers designed to be integrated into a panel or modular enclosure as part of an energy management system. These devices are recommended when a circuit requires a voltage different from that of the main power supply—for example, to power a doorbell, an intercom, a control circuit, or equipment operating at very low safety voltage. Depending on the model, ABB, Hager, and Legrand transformers can be mounted on a DIN rail and convert a 230 V primary voltage to a suitable secondary voltage, such as 12 V or 24 V.

It adjusts the supply voltage to provide a voltage compatible with an auxiliary, control, or signaling circuit.

It is used when low- or very low-voltage equipment cannot be powered directly from the 230-volt mains supply.

Yes, many ABB, Hager, and Legrand modular transformers are designed for DIN-rail mounting in an electrical enclosure.

The power, expressed in VA, must be sufficient to meet the total power consumption of the equipment connected to the secondary circuit.

A doorbell transformer typically powers a chime or a control unit, while a safety transformer provides very low voltage with reinforced insulation, depending on the model.
