Course EPT: Electro-Proportional Technology
Description
Introduces students to the fundamentals of electrically operated fluid power control components and their applications in mobile and stationary industrial equipment. Successful completion of this course allows students to understand the relationship of electrical voltage and current to the control of hydraulic flow, pressure and direction for commissioning, maintaining and troubleshooting modern hydraulic systems.

Attendance considerations:
Students should come prepared with a calculation device, toe guards/safety shoes, and eye protection/safety glasses. A selection of refreshments and lunches are provided, but may not meet dietary requirements.
Length
4.5 days

Cost
