  • Product Description:

    The HBControls HBC-25AS power controller is a ready-to-use Crydom A2425 solid state relay pre-assembled onto a compact, thermally efficient DIN mount “S” series heat sink. The HBC-25AS power controller assembly is fully derated to switch AC loads up-to 15 amps at line voltages between 24Vac and 280Vac in a 40°C ambient temperature. This eliminates the need to perform any thermal calculations or heat sink selection. Furthermore, since the A2425 is already assembled onto a specific, custom-designed heat sink, mounting torque and the application of thermal compound are no longer concerns.


    The HBC-25AS / A2425 solid state relay can accept control (input) signals between 90Vac and 280Vac. When an input signal is applied, the zero-crossing output circuit only conducts load current when the AC mains passes through the zero-crossing point of the sine wave. This minimizes inrush currents and the level of conducted emissions coupled onto the AC mains by the solid state relay.


    The A2425 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This significantly reduces the total power dissipation of the A2425 in comparison to similar triac output solid state relays, in addition to enhancing the relay’s ability to withstand heavy surge currents. This makes the HBC-25AS ideally suited for resistive heating and motor applications, or for switching power to other inductive loads with a power factor >0.5. The typical MTBF (mean time before failure) of the HBC-25AS / A2425 is >7 million hours. 


    Features and benefits of the A2425 & HBC-25AS solid state relay power controller 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)


    Additional options available:

    • Random / instantaneous turn-on version for phase-control or highly inductive applications (HBC-25AS-10)
    • Overvoltage protection (HBC-25AS-M)
    • LED status indicator (HBC-25AS-Z)
    • Panel mount (HBC-25AS-PM)
    • Two and three-pole versions for multiphase loads (-2 or -3 suffix)
