Power Relays, Over 2 Amps

JQ1A-5V are industrial control power relays designed to switch current over 2 amps in maximum. They are equipped with built-in safety features such as overcurrent protection and short-cycle protection, ensuring safe operation and wide range of applications.

Applications

The primary application range of JQ1A-5V is industrial control applications, including general machinery, textile machinery, automatic doors and windows, packaging and printing machines, stage stage lighting, elevators, electric power systems and other industrial automation fields. JQ1A-5V is also suitable for controlling AC/DC motors in a variety of machines and appliances.

Working Principle

In simple terms, JQ1A-5V comes with a power terminal, a load terminal and two control terminals, with built-in safety features to protect against overcurrent and short-cycle. The power terminal is connected to a power supply, the load terminal is connected to the load, and the control terminal can be connected to a switch or device. Once the switch or device is connected to the control terminal, the power is relayed through the medium of the relay, with the load terminal thus connected to the power terminal, thereby creating the desired electrical circuit.

The safety feature built into the JQ1A-5V ensures that the maximum current that can be switched through the relay is limited. This feature, coupled with the high dielectric strength offered by the relay, provides a safe and reliable operation.

In situations where the load current is expected to exceed the maximum current rating of the relay, it is advisable to use a current-sensing relay in conjunction with an overload relay for extra protection. This ensures that even if the load does exceed the maximum current rating of the relay, the overload relay will cut off the current and prevent the relay from failing.

Conclusion

JQ1A-5V are high-performance industrial control power relays capable of relaying AC/DC currents over 2 amps in maximum. The relays are equipped with built-in safety features such as overcurrent protection and short-cycle protection, providing a safe and reliable operation for a wide range of applications.
