Product Datasheet: HBControls UAF Series Single-Phase Power Controllers
Product Description:
The HBControls HBC-U125HDA-F power controller is a ready-to-use Celduc 125 amp solid state relay pre-assembled onto a compact, thermally efficient DIN mount “A” series heat sink. The HBC-U125HDA-F solid-state relay / heat sink assembly utilizes forced-air cooling and is fully derated to switch AC loads up-to 75 amps at line voltages between 24Vac and 510Vac in a 40°C ambient temperature. This eliminates the need to perform any thermal calculations or heat sink selection. Furthermore, since the solid-state relay is already assembled onto a specific, custom-designed heat sink, mounting torque and the application of thermal compound are no longer concerns.
The UAF series assemblies are available with either a 5Vdc or 24Vdc fan. Custom fan voltages may be available upon request.
The HBC-U125HDA-F solid state relay can accept control (input) signals between 3.5Vdc 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 HBC-U125HDA-F utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This significantly reduces the total power dissipation 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-U125HDA-F ideally suited for resistive heating and similar applications.
Features and benefits of the HBC-U125HDA-F 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)
