Control Transformers

Control transformers are essential devices in industrial and tertiary electrical systems. They are used to adapt the voltages of control circuits, providing galvanic isolation between the primary and secondary circuits. These transformers ensure the protection of equipment and people by reducing the risks of overheating and short-circuiting. Their applications are varied, ranging from control systems for machine tools to signalling circuits.Uses of control transformersControl transformers are commonly used in control panels, programmable logic controllers (PLCs), and signalling devices. They are designed to provide a stable voltage, often 24V or 48V, from a higher supply voltage. This protects sensitive electronic components from voltage fluctuations and overloads.These transformers are selected based on their ability to provide stable voltage under varying load conditions. They must also comply with the relevant standards, particularly EN 61558-2-2, which governs safety requirements for control transformers. Robustness, durability, and the ability to operate in harsh industrial environments are also essential criteria.
