Solid State Relays (SSRs) are electrical components in which the power level switching is enabled without the need of a physical contact between the load being switched and the relay itself. The AQG12124 is a specifically designed type of SSR with a growing presence in the industrial world. This article discusses the application field and working principle of the AQG12124.

Applications

The AQG12124 is suitable for a wide range of applications that require switching or controlling an electrical device with a power level current. It is mainly used in automation processes which regulate or control the flow of energy in a pre-determined manner such as in automated door locks, factory assembly lines and automated machine tools. This SSR is also commonly used in solar PV systems, fuel cells, HVAC systems, battery operated systems and other renewable energy applications as it can accurately control the flow of energy with precision and efficiency.

Working principle

The AQG12124 is an all-silicon based three-pin device that consists of two input pins, one for understanding the switch position of the user and the other for providing the response to the control signal. When an external control signal is applied to the appropriate pin, the current flows through the main terminal and its two outer pins the switch to its required position. This switch position can be reversed by reversing the input signal or applying a negative signal. The AQG12124 also contains an internal pull-up resistor that is provided to reduce the susceptibility of interference from external electromagnetic fields.

The AQG12124 also contains an integrated thermal control which senses the proportion of external power applied to it and accordingly adjusts its internal resistance to provide maximum efficiency and prevent any overheating or hot-spotting of the device. This internal safety measure ensures that the AQG12124 can operate in extreme conditions without damage or failure. This SSR also features a reverse current protection circuit which safeguards the device from unintentional reverse current flow due to any external force or power failure.

The AQG12124 is a reliable and efficient SSR ideal for use in applications that require precise switching and control of electrical device currents. With its wide range of features and benefits, the AQG12124 is an essential electrical component in the industrial arena.
