| 摘要 |
A low noise solid-state thermostat is provided designed to operate on AC power over a wide range of frequencies (e.g., from 0 Hertz (Hz) to 1000 Hz). The thermostat incorporates a soft start turn ON/OFF feature which reduces electromagnetic emissions (e.g., EMI). In addition, the thermostat is designed to provide common mode noise cancellation. Moreover, the thermostat uses state of the art complementary metal-oxide-semiconductor (CMOS) and metal-oxide-semiconductor field effect transistor (MOSFET) technology which improves reliability over conventional mechanical relays and thermostats. Custom temperature set points and custom temperature hysteresis can be selected at the time of production and/or subsequent to production.
