Abstract: A power controller monitors and controls supply of AC power to a load. A power supply derives DC power supply voltages from the input AC power. The power supply includes power dissipation circuit that dissipates excess power as a function of one of the supply voltages. A voltage sensing circuit provides a voltage sense signal that is a function of the voltage of the input AC power. A digital processor controls a switch that connects a load to the AC power based upon the voltage sensed signal.

Abstract: A drive system for a fluid displacement pump includes an electric motor, a drive coupled to the rotor at a first end of the electric motor, a pump including a fluid displacement member mechanically coupled to the drive, and a controller configured to control a level of power to the electric motor based on a pressure setting set by a user. The electric motor includes a stator and a rotor disposed on an axis. The drive coupled to the rotor converts the rotational output to a linear, reciprocating input to power a pump.
