What is an HBControls solid-state relay power controller?
An HBControls Power Controller is a solid-state relay pre-assembled onto either a DIN or panel-mount heat sink. Each Power Controller is ready-to-use, eliminating the need for thermal calculations or heat sink selection. The maximum allowable load current for the assembled solid-state relay in a 40°C ambient temperature is provided in the datasheet for each controller.
Solid-state relays are electronic relays that, unlike electromechanical relays and contactors, have no moving parts. As a result, their lifespan is significantly longer than comparable electromechanical relays. The typical MTBF (mean time between failures) for a solid-state relay is >7 million hours. Solid-state relays can also operate significantly faster, with on/off times measured in cycles rather than seconds. An instantaneous (also called a "random turn-on) solid-state relay can switch power to a load is less than 100µS.
Power controllers are similar to electromechanical relays and mercury contactors in terms of functionality. All of these devices switch power to or from an electrical load upon the application of an input or control signal. As previously mentioned, solid-state relays contain no moving parts, making them faster, quiet and highly reliable.
Some of the benefits of using a solid-state relay power controller are:
- Longer life expectancy and number of operations
- Resistant to shock and vibration
- Silent operation - no acoustical noise
- Fast response time
- No mechanical or moving parts

Does HBControls warranty their work?
Yes. Our solid-state relays and power controllers carry a standard one-year warranty. However, in case a manufacturing defect leads to product failure, it will be considered eligible for repair or replacement during its operational lifespan. If you have any questions regarding the quality of our products, want to voice your concerns or enquire about a return, please contact the HBControls Quality Control Department;
Quality Control Manager: HBControls, Inc. 18 Rosary Lane Hyannis, MA 02601 Tel: (800) 879-7918 / Fax: (508) 676-7346, www.hbcontrols.com.
HBControls will not be considered liable for any damage sustained apart from the repair or replacement of the equipment provided by the customer. HBControls takes no responsibility for additional parts, costs or labor incurred.
Does Thermal Fatigue Affect the Lifespan of HBControls Power Controllers?
A common misconception with solid-state relays is that high operating temperatures negatively affect the lifespan of a Power Controller. This is partially true, primarily in cases where the operating temperature exceeds the maximum specifications of the solid-state relay. In fact, solid-state relays can operate safely and reliably for decades at high operating temperatures, as long as maximum ratings are not exceeded. Instead, the real concern revolves around thermal excursions - the rate and frequency at which the the temperature within the solid-state relay changes.
Solid-state relays dissipate power in the form of heat during normal operation at a rate of approximately 1 Watt per ampere of load current. As a result, the internal temperature of the solid-state relay can increase rapidly if the heat sink to which it's mounted cannot adequately dissipate the heat. The subsequent expansion of internal components can eventually lead to thermal fatigue and the premature failure of the solid-state relay.
This is our area of expertise. HBControls Power Controllers utilize highly efficient heat sinks to prevent the solid state relay from overheating during normal use. Datasheets for each controller provide maximum allowable current ratings in a given ambient temperature, eliminating the need for thermal calculations or heat sink selection. We also offer custom power controllers with active cooling solutions for high-current applications or situations where the SSR controllers are used in high-temperature environments.
