The KUP-7A55-120 is the latest power relay from KUP, offering a range of features and advanced capabilities for heavy-duty applications. This article will explore the application fields and working principles of the KUP-7A55-120 power relay.

Application Fields of the KUP-7A55-120 Power Relay

The KUP-7A55-120 is designed for heavy-duty applications, offering a high-power capability and reliable operation. The relay is rated for up to 120 amperes and is suitable for applications requiring more than 2 amperes of current. Its robust design makes it suitable for a variety of circuits, including industrial motor controllers, power converters, and other energy-intensive applications.

The KUP-7A55-120 also offers superior noise immunity, allowing it to operate reliably and smoothly in electrically noisy environments. Its integrated shielding further improves its immunity to RF interference, making it well suited for automated systems that must operate reliably in a variety of environments. Overall, the KUP-7A55-120 is an ideal choice for robust and reliable power control in harsh industrial and electrical applications.

Working Principle of KUP-7A55-120 Power Relay

The KUP-7A55-120 is an electromechanical relay, meaning it uses an electrical current to control a mechanical switch. When the electrical current is applied, a small electromagnet creates a magnetic field, which in turn activates a mechanical switch. This switch is then used to open or close a circuit, allowing for remote and automated control of electrically powered components.

The KUP-7A55-120 is a latching relay, meaning it stores energy in an electromagnetic latch. This latch is energized when the relay is activated, and maintains the energized state even after power is removed. This allows the relay to remain active and maintain its current state, even when external power is not available. Latching relays are commonly used in applications where long-term and stable control of electrical components is required.

The KUP-7A55-120 also provides enhanced protection against over-current and over-voltage. It is equipped with thermal and surge protection features, allowing it to withstand spikes in current and voltage, ensuring reliable and safe operation. It also features a built-in auto-reset function, allowing it to reset itself automatically if it is overloaded by current or voltage.

Conclusion

The KUP-7A55-120 is a powerful and reliable power relay, suitable for heavy-duty applications requiring more than 2 amperes of current. It offers superior noise immunity, enhanced protection against over-current and over-voltage, and a latching design for reliable and stable control. With its robust design and reliable performance, the KUP-7A55-120 is an ideal choice for power control in harsh industrial and electrical environments.
