Efficient hydraulic power units for comprehensive compactor automation and method of using same

A hydraulic power unit for full compactor automation comprising:

• A housing, wherein the housing includes a support frame, an electrical control cabinet and a plate cover, wherein the support frame includes a front plate and a rear plate with a horizontal mounting plate there between, and wherein the frame includes front mounting channels coupled to the front plate, wherein the electrical control cabinet is coupled to the mounting channels, and wherein the plate cover is above the mounting plate;
• A hydraulic fluid reservoir supported by the housing;
• An electric motor on the housing;
• A hydraulic pump directly coupled to the motor;
• A Controller Area Network (CAN) control system mounted to the housing and wherein the hydraulic power unit measures a current draw by the electric motor and wherein a signal level associated with a measure of the current draw is fed to the Controller Area Network (CAN) control system whereby decisions about a compactor's fullness are based on the signal level;
• and
• An Integrated Circuit Hydraulic Manifold mounted to the housing including at least one Directional Control Valve, a Relief Valve, a Hydraulic Filter and a Check Valve.
