    Product Datasheet: Crydom Series1 Solid-State Relays

  • Product Description:

    The Crydom A2450 is part of the Series 1 range of solid state relays; Crydom’s “signature” product family and the most popular solid state relays in the market. The A2450 is capable of switching 50 amp loads at line voltages between 24Vac and 280Vac. Designed for endurance and reliability in harsh industrial applications, the A2450 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This significantly reduces the total power dissipation of the A2450 in comparison to similar triac output solid state relays, in addition to enhancing the relay’s ability to withstand heavy surge currents. The typical MTBF (mean time before failure) of a Crydom A2450 is >7 million hours.  

     

    The A2450 is an AC input solid state relay and can accept control signals between 90Vac and 280Vac. It incorporates an active current-limiting circuit, which enables it to switch 50 amp loads with only 10mA of input current. 

     

    The A2450 uses zero-crossing optical isolators to trigger the output SCRs. When an input signal is 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.

     

    Additional features and benefits of the Crydom A2450 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 A2450 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 A2450 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.
