DFKH-31-0002 Common Mode Chokes

Common Mode Chokes (CMC) are electromagnetic components commonly used in the fields of industrial automation and military engineering. They are designed to be used in electrical systems to reduce common mode electromagnetic interference (EMI). This type of interference can cause disruption to sensitive electronic components and damage them. CMCs help provide a path for EMI to dissipate to an external ground point, and can be used in high voltage switching systems, DC motor drives, and power inverters.The DFKH-31-0002 Common Mode Choke by Delphi Technologies is designed for use in high-power electrical systems. It is a three-phase panel mounted choke with a green anodized aluminum housing and an encapsulated epoxy. It features a wide temperature range of -40℃ to +125℃. This CMC is built for maximum electromagnetic interference suppression efficiency and is UL certified for safety. The working principle of the CMC is based on inductive current coupling. It works by coupling together the two coils of the CMC. It does this by passing a single-phase AC current in each of the two coils. This current then creates an inductive force between the coils which helps reduce EMI. The inductive force helps prevent EMI signals from passing through the device.It also works by creating an inductive voltage drop between the two coils. This voltage drop reduces the amount of current that can reach the external terminals. This helps reduce the amount of EMI caused by the current passing through the terminals. CMCs can also be used to reduce the noise generated by motors and other types of electrical equipment.The use of CMCs is also ideal for controlling the voltage imbalance in three-phase systems, and preventing resonance between the windings and cores of the transformer. The combination of an inductive voltage drop, coupling of the two coils, and the inductive force helps reduce EMI. This helps ensure the reliability of the system and its components.In summary, the DFKH-31-0002 three-phase panel mounted common mode choke by Delphi Technologies is designed for maximum EMI suppression efficiency. It has a wide temperature range and is UL certified for safety. It works by using inductive coupling and creating an inductive voltage drop. It is suitable for high-power electrical systems, reducing the amount of current that passes through the external terminals and preventing resonance. CMCs have many advantages and are widely used in the fields of industrial automation and military engineering.
