Solid State Relays (SSRs) are electrical devices used to control electrical circuits using low-power signals. They are commonly used in large control systems, such as industrial process control, automotive engine controls, and large-scale power systems. The EL240A20R-24H is a Solid State Relay (SSR) designed to control AC loads up to 24A. This article will examine the application field and working principle of the EL240A20R-24H.Application FieldThe EL240A20R-24H is designed for applications that require high switching capacity and high voltage isolation. It is suitable for Ac loads up to 24A and can operate from 24-460VAC. It can handle loads up to 20A continuous and 24A surge at -25°C to 80°C. The EL240A20R-24H is especially designed for applications where frequent switching is required such as in fans, AC inverters, throttles and motor control.Working PrincipleThe EL240A20R-24H is a type of Solid State Relay that uses an integrated circuit (IC) to control AC. The AC control component is a Triac or a combination of two SCRs. The inputs to the IC are the control signals from a logic circuit. When the control signal is a “1” a high current flows between the Triac or SCRs which turns on the device; when the control signal is a “0” a low current flows and the device is turned off.The output of the IC is then connected to a phase control element, usually a diode-connected Triac, which is connected to an AC load. The EL240A20R-24H uses a control circuit consisting of two N-channel MOSFETs which control the firing of the Triac. This allows for precise control of the firing angle of the Triac.The EL240A20R-24H offers several advantages compared to conventional relays. The most important advantage is its ability to switch AC current without sparking. This reduces the chances of fires and allows for quieter operation. The EL240A20R-24H is also more reliable than conventional relays as there are no moving parts which can fail over time. Furthermore, the EL240A20R-24H has zero leakage current, which means there is no current always flowing through the circuit even when the device is off.In conclusion, the EL240A20R-24H is a Solid State Relay designed to control AC loads up to 24A. It is suitable for applications that require high switching capacity and high voltage isolation. It is especially designed for applications where frequent switching is required, such as fans, AC inverters, throttles and motor control. The EL240A20R-24H offers several advantages compared to conventional relays, such as its ability to switch AC current without sparking and its zero leakage current.
