GENERAL DESCRIPTION

On/Off and Proportional Control Models
Quarter-turn reversing electric actuator with torque outputs from 300-13,500 in. lb, all on/off and proportional control models feature a Modular Design and Superior Gear Design as standard.

Unique EPM Standard Features:
Modular Design
All EPM Series actuators utilize modular PC boards designed and manufactured in North America. By eliminating 90% of the internal wiring found in most actuation products, we’re producing a higher quality, more reliable product that is easier to install, operate, and maintain.

Superior Gear Design
All EPM Series actuators employ an epicyclic gear design to provide tough, dependable torque transmission in a compact, quiet, smooth package.

Thermal Management
Our Proportional Control Actuators utilize proprietary, microprocessor-based algorithms to automatically control motor temperatures in real time with close-loop feedback.

Data Logging and Diagnostics
Our Proportional Control Actuators respond to a variety of control signals which are user-selectable through a simple joystick/menu interface. The microprocessor-based control monitors and records operating parameters that can be used for process diagnostics, advanced alarming functions or maintenance scheduling.

Proportional Control Models
All EPM Series Proportional Control Models feature added Thermal Management and Data Logging and Diagnostics capabilities not found on the basic EPM on/off models.
