Product Description:
The Crydom CWA2425 is a panel mount, IP20 touch-safe solid state relay capable of switching 25 amps at line voltages between 24Vac and 280Vac. Designed for endurance and reliability in harsh industrial applications, the CWA2425 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This significantly enhances the relay’s ability to withstand heavy surge currents and increases overall reliability and life expectancy. The typical MTBF (mean time before failure) of a Crydom CWA2425 is >7 million hours.
The CWA2425 is an AC input solid state relay and can accept control signals between 90Vac and 280Vac. The CWA2425 also includes an input LED for easy visual identification of the relay's status.
The Crydom CWA2425 uses zero-crossing optical isolators to trigger the output SCRs. When an input signal is initially applied, the output of the solid state relay will not conduct load current until the AC mains passes through the zero-crossing point of the sine wave. This greatly reduces inrush currents and minimizes the level of conducted emissions coupled onto the AC mains by the solid state relay.
The CWA2425 includes an integrated IP20 touch-safe cover.
Additional features and benefits of the Crydom CWA2425 solid state relay include:
- Direct bond copper (DBC) substrate for superior thermal performance
- Epoxy-free design to eliminate stress caused by the expansion and contraction of epoxy during normal operation
- Direct power lead frame design to minimize solder joints in the load-current path
- SEMS screws and washers for improved pull-out ratings
- Redesigned solid state relay housing with anti-rotation barriers
- Shock & vibration resistant to IEC 600068-2-6 & IEC 600068-2-27
- Agency approvals; cURus, CSA, VDE and CE compliant
- EMC compliant (level 3)
Typical applications for the CWA2425 solid state relay include; resistive heating, motor control and inductive applications with a power factor ≥0.5.
A heat sink and thermal compound are normally required to prevent a solid state relay from overheating during normal operation. The CWA2425 is used in a wide range of HBControls power controllers, which are solid state relays pre-assembled onto custom designed, thermally efficient heat sinks. Solid state relay power controllers offer enhanced reliability, performance and are fully derated to their maximum load current rating in a 40°C ambient environment.
