MCTC2450KHA

Solid State Relays

A solid state relay (SSR) is an electronic component that acts as a relay between input and output signal, without using any moving parts. It has no mechanical contacts and is made of semiconductor materials for switching function and control. The SSR consists of a semiconductor switch, such as a TRIAC or a MOSFET, mounted on an electronic circuit board. SSRs are faster and quieter than mechanical relays because they do not require any physical contact between the input and output circuits.

MCTC2450KHA Application Field and Working Principle

The MCTC2450KHA is a high power, low voltage, load-functioning, low dissipation, solid state relay (SSR) designed for industrial applications. It can be used to control or switch an electrical load from a low power signal. The load can be anything from a 50W bulb to a 5KW motor.

The SSR is constructed as an integrated circuit with two parts: a controlling terminal and a power terminal. The controlling terminal contains an input voltage follower with a low internal impedance. This, in combination with the power terminal, allows the device to turn ON, OFF, or even switch between ON and OFF in very short periods of time. The power terminal contains a series of field-effect transistors, controlled by the voltage follower, that act as an electronic switch.

The MCTC2450KHA can be controlled by various input signals, such as a TTL-level signal, a PWM signal, or even an analog voltage signal. Its input range is wide, from 7V to 20V. This means that it can be connected to many control circuits and industrial equipment for use in automation systems. It also has a powerful output, with a load current up to 5A, and a 100,000 sessions longevity.

When the input signal is set to a high level, the voltage follower turns the series of FETs on and the load current flows through the SSR. The internal MOSFETs act as a power switch and can handle high voltages and currents, allowing the SSR to control larger power loads. When the input signal is set to a low level, the voltage follower turns the FETs off, and the load current stops flowing.

The MCTC2450KHA is designed for reliable and accurate control and switching applications, making it an ideal choice for use in industrial, medical, and home automation applications. It is a compact and lightweight component that can be easily integrated into control systems for fast and reliable operation.
