HBControls Power Controllers are solid-state relays pre-assembled onto either a DIN-rail or panel-mount heat sink. Each Power Controller is fully assembled and ready to use, eliminating the need for thermal calculations or heat sink selection. The maximum allowable load current for the assembled solid-state relay, based on a 40 °C ambient temperature, is specified in the datasheet for each controller.
Solid-state relays are electronic switching devices that, unlike electromechanical relays and contactors, contain no moving parts. As a result, their operational lifespan is significantly longer than comparable electromechanical devices. Typical solid-state relays have an MTBF (mean time between failures) in excess of 7 million hours under rated operating conditions. Solid-state relays also operate much faster, with switching times measured in milliseconds or microseconds rather than seconds. An instantaneous (also called “random turn-on”) solid-state relay can switch power to a load in less than 100 µs.
Solid-state relay power controllers perform the same basic function as electromechanical relays and mercury contactors: switching power to or from an electrical load in response to an input or control signal. However, because solid-state relays have no moving parts, they offer faster response times, silent operation, and significantly higher reliability.
Benefits of using a solid-state relay power controller include:
Long operational life and high number of switching cycles
Resistance to shock and vibration
Silent operation with no acoustical noise
Fast response time
No mechanical or moving parts
A common misconception is that high operating temperature alone significantly reduces the life expectancy of a solid-state relay. While excessive temperature can contribute to failure, long-term reliability is more strongly affected by thermal cycling, also known as thermal fatigue, rather than steady-state temperature itself.
Thermal fatigue results from repeated thermal excursions—changes in temperature that occur as the relay heats up and cools down during normal operation. Solid-state relays dissipate power in proportion to the load current they conduct. If heat is not removed efficiently, the internal temperature of the relay can rise rapidly. When operating conditions change—such as load cycling, duty-cycle variation, or ambient temperature shifts—the relay experiences repeated heating and cooling cycles.
These temperature fluctuations place mechanical stress on internal materials because different components expand and contract at different rates. For example, the copper conductors that carry load current expand at a different rate than the solder joints and semiconductor materials used within the relay. Over time, repeated thermal cycling can fatigue these interfaces, leading to cracked solder joints, degraded connections, and ultimately premature device failure.
HBControls solid-state power controllers are designed to minimize thermal fatigue by using appropriately sized, high-efficiency heat sinks that reduce both peak operating temperature and the magnitude of thermal excursions. For high-current applications or installations operating in elevated ambient temperatures, active cooling solutions—such as forced-air cooling—are also available to further improve thermal stability and extend service life.
