Power relays are electrical switches that are electronically or magnetically operated. The KHAU-17A11N-120 is a power relay designed to switch over 2A of current when activated. This makes it ideal for a range of mains voltage applications, such as controlling motors, HVAC systems and lighting. The device has a variety of features, including a low-power coil, two form-C contacts, and a normally open switch contact.

KHAU-17A11N-120 Application Field

The KHAU-17A11N-120 is suitable for a variety of applications involving the switching of electrical circuits. In HVAC and heating and cooling systems, the relay can be used for the control of compressors, fans, controllers and other equipment. The device is also well-suited for industrial applications, such as controlling motors and pumps, controlling machine tools, and providing overload protection. Other applications include sound and lighting systems, security systems, valves, solenoids and other general purpose switching.

KHAU-17A11N-120 Working Principle

The KHAU-17A11N-120 is a latching relay, meaning it requires an initial pulse of energy in order to activate the switching mechanism. Once the relay has been triggered, it is maintained in its current state until it receives a further activating or deactivating pulse. This feature allows for greater control and for simpler wiring, as a single control signal can be used to switch the relay on or off. The device has two separate contacts, one normally open contact and one normally closed contact. These contacts can be used to control current on two separate circuits, or to control the same circuit by controlling the current in opposite directions.

The relay has a coil that is activated by an externally provided electrical voltage. When the voltage is applied, the coil generates a magnetic field that pulls the contact arm and closes the contacts. The contact arm can be pushed back by a reverse magnetic field and electrical current, which will open the relay and turn off the circuit. The power relay features a low-power coil, which conserves energy and ensures a long service life.

The KHAU-17A11N-120 Power Relay is an excellent choice when a reliable switching device is needed to control current ratings up to 2A. The low-power coil and two-contact design make this device highly versatile and suitable for a wide range of applications.
