KHU-17A11-120

Power relays are electrical switches that open and close circuits electromechanically or electronically. When current is passed through a power relay, the electromagnetic field generated by this current causes the contacts of the power relay to close or open, depending on the design, voltage, and current rating of the power relay.The KHU-17A11-120 is designed to switch high currents (rated up to 2 Amps) that are too much for smaller, more conventional relays. This heavy-duty power relay is both reliable and durable, making it suitable for a variety of applications.

Design

The KHU-17A11-120 has a unique design that allows it to switch high currents. The contacts are sealed in a protective case, which prevents debris or dust from entering and obstructing the contacts or electrical paths. The cover of the power relay is rated up to IP67, meaning it is dustproof and waterproof. The materials used in the construction of the KHU-17A11-120 can withstand extreme temperatures ranging from -40°C to +70°C, making it suitable for outdoor applications.

Working Principle

The KHU-17A11-120 works by passing current through a coil, which creates an electromagnetic field. This magnetic field then causes the contacts of the power relay to close or open, depending on the voltage and current rating of the power relay. The power relay can be designed to work in both normally open (NO) and normally closed (NC) configurations. In a normally open configuration, the power relay will remain open until a signal is provided and the contacts close. In a normally closed configuration, the power relay will stay closed until a signal is provided, and the contacts open. The KHU-17A11-120 also features low voltage dropout and a low power consumption, making it ideal for applications with limited energy sources.

Application Field

The KHU-17A11-120 is a versatile power relay suitable for a variety of applications, including automotive, industrial, and telecom. It can be used to control high currents, such as in motor control applications. It is also suitable for switching higher-voltage AC circuits, such as in heating and lighting applications. This power relay can also be used in safety circuits, such as for connecting fire alarms or smoke detectors. Additionally, the KHU-17A11-120 can be used in audio/video applications such as power amplifiers and audio streamers. It can also be used for switching high currents in solar applications.

Conclusion

Overall, the KHU-17A11-120 a versatile and reliable power relay suitable for a variety of applications. It is designed to switch high currents of up to 2 Amps and is designed to be dustproof and waterproof with a rating up to IP67. It can be used in a wide range of applications, such as motor control, safety circuits, audio/video, and solar. The KHU-17A11-120 is a reliable and durable power relay that can handle high currents with ease.
