CD2450E2VH Solid State Relays

CD2450E2VH is a type of solid state relay (SSR) that can be used to control and switch AC and DC circuits. It is especially suitable for industrial automation applications including motor control, power switching, temperature control, and other applications that require switching at high current and voltage levels.

CD2450E2VH is a low cost, fast switching, and low dissipation solid state relay. It uses a TRIAC and a light-activated SCR (LASCR) as its switching element for AC switching and a bipolar-junction transistor (BJT) for DC switching. As such, the CD2450E2VH has a much higher switching speed than other SSRs since its switching element has an near-impulse response characteristic.

The maximum load current for CD2450E2VH is up to 25A and maximum load voltage is up to 480VAC. It also has a high input signal sensitivity of 1V rms. The AC output resistance of this SSR is up to 0.25 milliohm and the leakage current is up to less than 3mA under its rated voltage and current.

The CD2450E2VH is very stable when working for a long time. Moreover, it features robust electromagnetic interference (EMI) and radio frequency interference (RFI) immunity, making it suitable for all types of industrial environments. Furthermore, this robust SSR is designed for low thermal resistance and has a robust mechanical design to withstand shocks and vibrations.

Application Field

CD2450E2VH is suitable for controlling and switching AC and DC circuits in industrial automation and other applications. The CD2450E2VH is a low-cost, fast-switching, and low-dissipation SSR that can be used in many different applications. It can be used for switching at high AC and DC voltages and currents, as well as for applications that involve switching some temperature or power. This SSR is also suitable for applications with high EMI and RFI immunity, low thermal resistance, and robust mechanical design.

Working Principle

The CD2450E2VH SSR is a 3-terminal device with a control input, a switchable output (described here), and a common terminal (described here). It works by using a TRIAC and a light-activated SCR (LASCR) as its switchable element for AC switching, and a bipolar-junction transistor (BJT) for DC switching. When a gate voltage is applied to the control terminal, current is allowed to flow through the TRIAC or BJT, and the SSR is in its “on” state.

When the control voltage is removed, the TRIAC or BJT is turned off and the SSR is then in its “off” state. This solid state relay also has a much higher switching speed than other SSRs because its switching element has an near-impulse response characteristic. This makes it very suitable for fast cycling applications, such as temperature and power control.

In conclusion, CD2450E2VH is a robust and versatile solid state relay which is especially suitable for industrial automation applications, including motor control, power switching, temperature control, and other applications that require switching at high current and voltage levels. Moreover, its high switching speed, low cost, and high input signal sensitivity are beneficial features to consider when choosing this relays.
