Temperature Sensors - Thermostats - Solid State

The Results of Temperature Sensors - Thermostats - Solid State 516
Solid state thermostats and thermal switches provide on/off temperature control without moving parts — using electronic temperature-sensing ICs combined with built-in relay or triac output to switch loads directly. They are used in HVAC zone control, motor protection, thermal runaway protection in battery packs, 3D printer heated beds, industrial ovens, and medical refrigeration. Our solid state thermostat inventory covers adjustable and fixed-temperature electronic thermostats with output ratings from 5A to 25A, supply voltages from 12V to 240V AC/DC, and switching temperatures from –30°C to +150°C — from brands including Cal Therm, Heat-Kit, Runo, and Jumo. Specific thermal switch and thermostat assemblies for HVAC equipment and industrial motor protection are frequently on long lead times or end-of-life. Welllinkchips stocks a range of solid-state thermostat configurations and can source discontinued thermal switch types needed for legacy HVAC and industrial heating equipment repair.
