HA6025

The Crydom HA6025 is an industry-standard, panel mount "hockey puck" solid state relay capable of switching 25 amp loads at line voltages between 48Vac and 660Vac. Designed for endurance and reliability in harsh industrial applications, the HA6025 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This design significantly reduces total power dissipation and enhances the relay’s ability to withstand heavy surge currents, with a typical MTBF of over 7 million hours.

The input accepts control signals between 90Vac and 280Vac and features an active current-limiting circuit, allowing it to switch 25 amp loads with only 10mA of input current. The HA6025 uses zero-crossing optical isolators to trigger the output SCRs, minimizing inrush currents and conducted emissions.

Additional features include a Direct Bond Copper (DBC) substrate for superior thermal performance, an epoxy-free design, and a direct power lead frame design to minimize solder joints. It is shock and vibration resistant and meets agency approvals including cURus, CSA, VDE, and CE. Typical applications include resistive heating, motor control, and inductive loads with a power factor of 0.5 or greater. A heat sink and thermal compound are normally required for operation.
