Product Datasheet: HBControls L Series Power Controllers
The HBControls HBC-90HDL power controller is a ready-to-use Crydom HD4890 solid state relay pre-assembled onto a thermally efficient DIN mount “L” series heat sink. The HBC-90HDL power controller assembly is fully derated to switch AC loads up-to 50 amps at line voltages between 48Vac and 530Vac in a 40°C ambient temperature. This eliminates the need to perform any thermal calculations or heat sink selection. Furthermore, since the HD4890 is already assembled onto a specific, custom-designed heat sink, mounting torque and the application of thermal compound are no longer concerns.
The HBC-90HDL / HD4890 solid state relay can accept control (input) signals between 4Vdc and 32Vdc. 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 HD4890 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This significantly reduces the total power dissipation of the HD4890 and enhances the relay’s ability to withstand heavy surge currents. This makes the HBC-90HDL 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-90HDL / HD4890 is >7 million hours.
Features and benefits of the HD4890 & HBC-90HDL 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-90HDL-10)
- Overvoltage protection (HBC-90HDL-M)
- LED status indicator (HBC-90HDL-Z)
- Panel mount (HBC-90HDL-PM)
- Two and three-pole versions for multiphase loads (-2 or -3 suffix)
