Product Description:
The HBControls HBC-U50DN power controller is a ready-to-use Celduc SO945460 50 amp solid state relay pre-assembled onto a thermally efficient panel mount “N” series heat sink. The HBC-U50DN power controller assembly is fully derated to switch AC loads up-to 45 amps at line voltages between 12Vac and 280Vac in a 40°C ambient temperature. This eliminates the need to perform any thermal calculations or heat sink selection. Furthermore, since the SO945460 is already assembled onto a specific, custom-designed heat sink, mounting torque and the application of thermal compound are no longer concerns.
The HBC-U50DN / SO945460 solid state relay can accept control (input) signals between 3Vdc 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.
A green LED provides visual indication when the input signal is applied.
The SO945460 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This significantly reduces the total power dissipation of the SO945460 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-U50DN ideally suited for resistive heating and similar applications. The typical MTBF (mean time before failure) of the HBC-U50DN / SO945460 is >7 million hours.
Features and benefits of the SO945460 & HBC-U50DN 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)
