The electrical regulator is connected to a load.

The supplementary Battery feeds the supplementary linear D.C. electric motor via electric regulator and electric relay/contactor.

The supplementary Battery feeds the supplementary linear D.C. electric motor via electric regulator and micro switch.

The communications interface (806) allows digital control of the networkable power controller.

The generated electrical power feeds electrical loads via an electric convertor and feeds a supplementary linear D.C. electric motor via a supplementary electric regulator.

The power supply control circuit (3) provides proper control over the supply and shutoff of the electrical power for each of the functional blocks, whereby each of the functional blocks consumes reduced electrical power.

Due to the recent lightning strike, the power regulator continues to be inoperative.

A cooling system that has an electrical controller that controls an electric expansion valve and the defrost cycle using a reversing valve.

The need for heater circuit to achieve defrost is eliminated.

An electric control (113), including a processor (108), for developing the electric control signal from a primary control signal and a secondary control signal.

A power control circuit (50) for improved temperature control of thermoelectric devices to maintain the temperature of thermoelectric devices at a set point.
