CD2425E3VRH

Solid State Relays (SSR) are the devices that containing no moving parts, unlike conventional electromechanical relays. They operate by using semiconductor technology or by application of optical or magnetic properties for switching. They are used in numerous industrial, commercial, and consumer applications, and are particularly advantageous in applications where long life, silent operation, and high switching speeds are required. CD2425E3VRH is one of the solid state relays with solid performance.

CD2425E3VRH is a single-pole double throw (SPDT) Optically-Isolated Solid State Relays (SSR) used for switching applications from DC to AC operation. It is an improved version of the popular CD2425E3V and is suitable for use in all types of switching applications. It is designed with a special insulating glass epoxy resin package to ensure reliable performance and high insulation. The device features a standard optically isolated triac gate with built-in temperature compensation and noise immunity circuit. It is rated for 5A at 30V DC/AC and 10A at 125V AC.

The CD2425E3VRH is designed for use in high-reliability and noise-sensitive switching applications. It includes a built-in voltage clamp that prevents damaging voltage transients from occurring during switching and ensures noise immunity from electrical transients. It also features an internal surge suppression circuit that prevents current spikes during switching. All these features combined make it ideal for use in high-reliability and noise-sensitive switching and control applications.

The working principle of CD2425E3VRH is based on an optically isolated triac gate. When the input voltage is applied, the triac gate opens, allowing the current to flow from the input to the output. During this time, the voltage across the triac gate switches from a low-voltage to a high-voltage state, ensuring that no current flows until the input voltage reaches a certain level. The built-in temperature compensation and noise immunity circuit provide a reliable and noise-free operation even in adverse environmental conditions.

The CD2425E3VRH is typically used in the control of electronic switches, pressure and flow transducers, lamp dimmers, AC motor speed controllers, HVAC systems, battery chargers, and other industrial automation applications. It is suitable for being used in applications that required reliable performance in harsh environments with high levels of electromagnetic interference. Its excellent performance with low cost and small size makes it an ideal choice for high-reliability and noise-sensitive switching applications.
