AQZ202G

Solid State Relays (SSRs) are devices that are able to control the flow of electrical power in response to an input signal. They are commonly used in a wide range of applications and industries such as factory automation, process control, and consumer electronics. One such Solid State Relay is the AQZ202G, which is a low-cost, high-power solid-state relay solution. This article will discuss the application fields and working principle of the AQZ202G.The AQZ202G is suitable for a wide range of applications, such as motors controlling, air conditioners, small home appliances, and LED lighting (various types of loads). It is a compact, low-cost, and high-power solution, allowing for flexibility in system design. It is applicable to both AC and DC power, with a maximum load of 250V/24A, and a maximum operating voltage of 28VDC.The working principle of the AQZ202G is based on the concept of a thyristor. A thyristor is a semiconductor device that consists of four layers of alternating n-type and p-type silicon material. When the anode and cathode of the thyristor are forward biased, the thyristor can be activated by a current pulse applied to the gate. When the voltage level of the circuit is equal to or greater than the voltage holding level of the thyristor, current will start to flow, allowing the thyristor to act as a switch.The AQZ202G uses this principle of a thyristor to provide a high-power solution. It consists of two main components: a sensing module and an output module. The sensing module comprises of a high-precision differential amplifier, which detects the voltage and current levels. This information is then sent to the output module, which consists of the four-layer thyristor device. Based on this information, the thyristor is activated, allowing current to pass through the load connected to the AQZ202G.The AQZ202G also provides overload protection, which is essential to protect the system. This is achieved via a thermal switch within the AQZ202G, which senses the voltage and current levels passing through the thyristor. When the levels exceed certain thresholds, an alarm is triggered, and the thyristor is disabled. This prevents the AQZ202G from overloading, as well as protecting the system and preventing damage.In summary, the AQZ202G is a cost-efficient and high-power solid-state relay solution that can be used for a wide range of applications. It is suitable for use with both AC and DC power, with a maximum load of 250V/24A. The working principle is based on the concept of a thyristor device, which is activated when the voltage and current levels reach a certain level. The AQZ202G also provides overload protection, ensuring the system is protected from overloading.
