Collection: Solid State Relay
Solid State Relays for Precision Power Switching
QITAI solid state relays deliver silent, fast, and durable switching: QSRM mini (10-25A), QSN/QSR single-phase (10-125A), QSRD dual, QSJ DC, QSQF/QSQE three-phase, and QMTY motor reversing relays, plus voltage regulators and DIN rail types.
With zero mechanical wear and instant response, our SSRs are ideal for industrial heating, motor control, and power switching applications where contactors fall short. Built-in thermal protection extends service life.
Factory direct with free samples and 12-month warranty — switch to QITAI SSR reliability.
