G5Q-1A DC12 Application Field and Working Principle
G5Q-1A DC12 is a high-performance, high-sensitivity power relay. It is used in various power control applications from low current to high current, including switching of single-phase and three-phase power circuits with AC and DC power sources. The main features of G5Q-1A DC12 power relay are the strong driving force, miniaturization and superior reliability.
G5Q-1A DC12 power relay is mainly composed of two parts: the contact and the coil. The contact is a switch. It controls the on/off of the load. The coil is an electromagnetic device. It supplies the switching energy to the contact for controlling the on/off of the load. Motor, switch, contactor, etc. are the common contact type of the G5Q-1A DC12.
The working principle of G5Q-1A DC12 relay is simple. When the voltage or current of the coil reaches the set value (pick up voltage or pick up current), the magnetic field produced by the coil attracts the armature of the contact and drives it to pull the static contact to the dynamic contact, thus making the circuit switch normally. When the voltage or current of the coil drops under the set value (drop off voltage or drop off current), the armature moves away from the dynamic contact due to the lack of the magnetic field, thus disconnecting the circuit.
Generally speaking, this power relay has the following advantages. Firstly, its operating voltage and current range are wide. Secondly, its switching speed is very fast. Thirdly, it is very sensitive, its response time is very short and its contact is durable. Last but not least, its contacts are dustproof and shockproof.
G5Q-1A DC12 power relay can be widely used in the field of home appliance control, car navigation system, electronic device control, automatic control system, power switch control, motor protection, power line protection, etc. Its application range is diverse.
In summary, G5Q-1A DC12 is a multi-function power relay. It has high sensitivity, strong driving force, wide voltage and current range, fast switching speed, dustproof and shockproof performance. It is widely used in various power control applications.
