1. What is a control transformer
The control transformer is a small dry-type transformer.
The control transformer is mainly suitable for AC 50Hz (or 60Hz), voltage 1000V and below circuits, and can work continuously for a long time under rated load.
It is usually used in machine tools and mechanical equipment as the control lighting and indicator power supply of electrical appliances.
The parameters commonly used in practical applications are 380V to 220V, 380V to 36V, 380V to 24V, 380V to 12V and 220V to 36V, 220V to 24V, 220V to 12V.
In addition to being used as a buck-boost power supply, a control transformer can also transmit signals, that is to say, a control transformer is an electrical appliance that can transmit electrical energy or transmit signals from one circuit to another.
2. How do control transformers work?
In low-voltage power distribution systems, control transformers are named for their use in control systems. It is actually a step-down transformer with multiple output voltages.
The control transformer works on the principle of electromagnetic induction.
A transformer has two sets of coils, a primary coil and a secondary coil.
The secondary coil is outside the primary coil. When the primary coil is connected to alternating current, the transformer core generates an alternating magnetic field, and the secondary coil generates an induced electromotive force.
The turns ratio of the coils of a Satons transformer is equal to the voltage ratio.
3. Control Transformer Wiring Diagram
The commonly used parameters of control transformers in practical applications are 380V to 220V, 380V to 36V, 380V to 24V, 380V to 12V, 220V to 36V, 220V to 24V, 220V to 12V.
The following figure is a common control transformer wiring diagram for your reference.
4. What are the advantages of control transformers？
Control transformers are a type of transformers that are widely used, so what are the advantages, characteristics and precautions of this series of transformers?
In terms of advantages, control transformers have the following advantages:
- Good thermal stability, product design and process are strictly implemented, coils and core leads are made of high-quality materials, and the current density is selected low.
- Strong overload capacity: The product has strong overload capacity and overvoltage capacity, which can meet the overload requirements.
- Small Appearance: Simplified structure and beautiful appearance.

7. What are the benefits of using a control transformer?
A control transformer is required to supply voltage to a load which requires significantly more current when initially energized than under normal steady state operating conditions.
A control transformer is designed to provide secondary voltage stability under a short period of specific overload referred to as inrush.
8. Control transformer usage environment
The ambient air temperature is -5°C to +40°C, and the 24-hour average does not exceed +35°C;
The altitude of the installation site shall not exceed 2000M.
Atmospheric relative humidity does not exceed 50% when the ambient air temperature is +40°C, and can have higher relative humidity at lower temperatures, and the monthly average maximum humidity in the wettest month is 90%.
At the same time, the average minimum temperature for the month is +25°C, taking into account the condensation that occurs on the product surface due to temperature changes.
