Why Choose the Lovato HSBXH4D024 Solid State Relay Heatsink?
The Lovato HSBXH4D024 is a high-performance forced-air heatsink for solid state relays, designed to provide effective thermal management for compatible Lovato HS series switching devices. As part of the Lovato HSBX solid state relay accessories range, it combines a substantial aluminium heatsink with an integrated 24 V DC cooling fan to increase heat dissipation in demanding industrial applications.
The HSBXH4D024 is designed for use with one compatible Lovato HS1B or HS2B solid state relay. Its forced-air cooling arrangement provides a specified heatsink thermal resistance of 0.3 K/W, allowing heat generated by the semiconductor switching device to be transferred efficiently away from the relay during operation.
Designed for industrial heating, machinery and automation installations, the HSBXH4D024 is particularly useful where higher SSR currents or elevated thermal loads require more effective cooling than a passive heatsink can provide. The integrated 24 V DC fan delivers continuous airflow across the heatsink fins, supporting reliable relay operation and effective thermal management within electrical control panels.
Key Advantages
- Purpose-designed forced-air heatsink for Lovato solid state relays.
- 0.3 K/W heatsink thermal resistance for effective heat dissipation.
- Integrated 24 V DC cooling fan provides forced-air cooling.
- Designed for one compatible HS1B or HS2B solid state relay.
- Supports reliable SSR operation under demanding thermal conditions.
- Compact integrated heatsink-and-fan solution for industrial control panels.
Key Features
- Lovato HSBX solid state relay accessory range.
- 0.3 K/W thermal resistance.
- Complete with integrated 24 V DC fan.
- Designed for HS1B and HS2B solid state relays.
- Suitable for one compatible solid state relay.
- Forced-air thermal management for higher heat dissipation.
- Designed for industrial electrical, heating and automation installations.
- Compatible with Lovato thermal pads for effective heat transfer between the SSR and heatsink.
Forced-Air Cooling for Solid State Relays
Solid state relays generate heat while conducting load current because their semiconductor switching elements have a small on-state voltage drop. Effective removal of this heat is essential for maintaining acceptable semiconductor junction temperatures and supporting reliable operation, particularly at higher switching currents.
The Lovato HSBXH4D024 combines a heatsink with a 24 V DC fan to provide forced-air cooling and a specified heatsink thermal resistance of 0.3 K/W. A suitable thermal interface pad should be installed between the relay and heatsink to optimise heat transfer, while the applicable Lovato SSR derating data should be considered when determining the permissible load current for the installation.
Typical Applications
- Thermal management of compatible Lovato HS1B solid state relays.
- Thermal management of compatible Lovato HS2B solid state relays.
- High-current industrial electric heating control.
- Industrial ovens and resistive heater systems.
- Temperature-controlled process equipment.
- Packaging and production machinery.
- Industrial automation and machine-control panels.
- Applications requiring enhanced forced-air SSR cooling.
