Abstract
An HVAC actuator (1) comprises an electric motor (11); an energy buffer (13) configured to store electrical energy from a power supply (2), and to provide the electrical energy to the motor (11); and a power limiting circuit (12) configured to limit input power from the power supply (2) to the energy buffer (13) to a threshold lower than motor power drawn by the motor (11) from the energy buffer (13).
