ABSTRACT:
A power supply circuit for a temperature control system is switchable between a low input impedance mode and a high input impedance mode, so that a temperature control system having this power supply can directly replace a bimetallic switch and the power supply will look to the rest of the system like the replaced bimetallic switch.
