CD2425E4UR

Solid State Relays (SSRs) are devices used to control current flow through a circuit. They work by using a semiconductor device, such as an insulated-gate bipolar transistor (IGBT) as a switch, which actuates when a voltage is applied across the terminals of the device. The CD2425E4UR is a type of SSR that is used in a wide range of applications including power control, audio/video switching, temperature control, and switching high current loads.

The CD2425E4UR is designed for providing a fast and clean switching action with low loss and high speed. It features a very low on-state resistance, making it ideal for high current loads. It utilizes an AC-input with a logic high output of 5 volts and a logic low output of 0 volts which is suitable for most applications. The device is suitable for operating up to 25A at upto 440VAC and is suitable for 50/60Hz AC applications.

The CD2425E4UR has two main components: a control circuit and an output driver. The control circuit is composed of a comparator, a resistor, and a capacitor. The comparator is connected to the control input and, when a voltage higher than the trip point is applied to its input, the output of the comparator goes high, turning on the power to the output driver. The output driver is composed of a transistor and capacitor. When power is applied, the transistor conducts current from the capacitor, energizing the output. The capacitor drains current through a resistor which helps the output turn off when the input voltage is removed.

In addition to providing fast and reliable switching, the CD2425E4UR is also designed to be highly reliable and durable. It is designed with a very low failure rate thanks to its solid state construction and advanced design features. The device is also designed to be highly resistant to EMI, vibration and extreme temperature, making it suitable for most demanding applications.

In conclusion, the CD2425E4UR is a solid state relay that is ideal for controlling high current loads and providing fast reliable switching. It features an on-state resistance of very low resistance, making it suitable for applications with high current loads. It is also designed to provide reliable, durable operation in extreme conditions while also featuring increased protection against EMI.
