Solid State Relays (SSRs) have found increasing popularity in many applications. One of the most popular SSR products is the D4875K, a single-pole, solid-state relay with a wide range of applications and features. It is commonly deployed in switchgear, motor control, and power systems engineering.

The D4875K is a medium-current solid-state device, featuring an optically isolated input and zero-crossing AC output. It requires only 5mA of input current to operate, making it suitable for low-voltage control circuits, such as those found in microcontrollers. The D4875K is also capable of photoacoustic or resistance welding applications, where higher temperatures and current loads must be tolerated.

The D4875K SSR is perfect for single-pole switching applications that require high power and high current ratings. The device has a nominal AC output current of 60A, with a maximum inductive load of 120A. The device is equipped with fast switching times, with response times of only 0.2ms after the input signal is applied. In addition, the device is designed with a wide input voltage range of 10 to 12V, and a wide range of allowable temperature ranges, from -25°C to +85°C.

The D4875K has a very useful self-protection feature, which allows it to turn off in the event of overloads or temperature swings. This feature safeguards the device from any potential damage or malfunction. It also has an input sensitivity adjustment capability, which allows for the devices to react at different speeds and output levels, depending on the application.

The working principle of the D4875K is based on the utilization of a semiconductor switch, in this case, a MOSFET. The device contains a control circuit, which is used to control the gate voltage of the MOSFET. When an input voltage is applied to the control circuit, it will turn ON the switch, thus allowing the AC output power to flow. When the input voltage is removed, the switch is opened, thus stopping the output current.

The D4875K SSR is perfect for applications in which single-pole switching is required with high power and current ratings. Its fast switching times and overload protection capabilities make it suitable for many different applications. Furthermore, its wide input voltage range and temperature range make it an attractive solution in many different industrial and commercial applications.
