Power relays, over 2 Amps, can be found in a variety of applications throughout commercial and industrial settings. HJ4-L-AC120V-6 is a good example of a power relay designed specifically for applications with pulsed operation. In this article, we will look at the purpose and working principle of the HJ4-L-AC120V-6.

Purpose of HJ4-L-AC120V-6

The HJ4-L-AC120V-6 is designed to be used in systems where the power supply is normally high (in excess of 110 volts) and requires the use of a relay to protect it from overloads and short circuits. This type of power supply can be found in a wide range of applications such as motors, pumps, and air conditioners. The HJ4-L-AC120V-6 is also suitable for use in high current applications such as automotive and industrial system controllers.

The HJ4-L-AC120V-6 is also designed for use with pulsed operation, where the power supply must be disconnected after a predetermined interval. In such applications, the pre-programmed pulse rates are used to ensure that the power is safely disconnected once the interval has elapsed. The pulse rates available with the HJ4-L-AC120V-6 range from 0.15 seconds to 16 seconds, making it suitable for most power management applications.

Working Principle of HJ4-L-AC120V-6

The HJ4-L-AC120V-6 is a power relay that contains two basic components: a contactor and a switch. The contactor, or contact arm, is a metal arm that is held in place by a spring. When an electric current is passed through the contactor, the spring releases, activating the switch. The switch then either connects or disconnects the power to the device being powered.

The HJ4-L-AC120V-6 has two operation modes. The first mode is the continuous operation mode. In this mode, electricity is constantly supplied to the device and the contactor and switch never open or close. The second mode is the pulsed operation mode, where the current is only supplied for a predetermined period of time. The HJ4-L-AC120V-6 is pre-programmed to supply the current for a particular period of time, ranging from 0.15 seconds to 16 seconds.

When the predetermined period has elapsed, the contactor and switch open. This shuts off the current and power supply to the device, protecting it from overloads and short circuits. The HJ4-L-AC120V-6 is also designed to have a delay period before it reconnects the power supply, protecting the device from current surges.

Conclusion

The HJ4-L-AC120V-6 is designed for use in applications requiring pulsed operation, typically in applications involving motors, pumps, and air conditioners. The HJ4-L-AC120V-6 is pre-programmed to supply electricity for a predetermined period of time before automatically shutting off the power supply, protecting the device from overloads and short circuits. The delay period before reconnecting also increases its overall safety features.
