MCBC4890EL

Solid state relays (SSR) are switching devices that utilize input voltage to control the operation of an output device for controlling electrical circuits. SSRs use an opto-isolator to create electrical isolation between the input and output. The MCBC4890EL is a type of SSR specifically designed for use in low power, high reliability applications.

The MCBC4890EL is a compact device with a high-efficiency AC output. It features an integrated opto-isolator, allowing it to isolate the output from the input and provide a secure connection. The device also includes a PTC thermistor to protect against output current surges, and an over-temperature protection feature.

The MCBC4890EL is designed for use in low-power applications such as telecom switches, SMPS applications, variable frequency drive systems, and motor control applications. It has a wide input voltage and operating temperature range, making it suitable for use in a wide range of environments. In addition, the device features a high switching frequency, allowing it to be used in high-speed applications.

The MCBC4890EL operates using a low-side switch configuration. When an input voltage is applied, the opto-isolator isolates the power between the input and output. This is done by using an LED emitter located inside the opto-isolator, which produces a photocurrent when the LED is energized by the input voltage. This photocurrent flows through a photo-transistor, causing the transistor to conduct. The transistor then turns on, allowing the output power to be connected.

The MCBC4890EL is a reliable, low-cost SSR solution for low power applications. Its low-side switch configuration is ideal for applications where the input voltage is not always connected to the output. In addition, its PTC thermistor and over-temperature protection features provide added reliability. This makes it a great choice for use in low-power, high reliability applications.
