Model ESA-CXA Electrostrictive Actuator Controller
Actuator Compatibility
This unit is intended for use only with Newport AD Series
electrostrictive actuators.
Caution
Clamp-type micrometer/actuator mounts are
capable of very high clamping forces. Do not
over-clamp the actuators! Tighten the clamp
only as much as necessary to firmly grip the
actuator. Performance degradation and/or
damage can occur if the clamps are
overtightened.

1. On/Off switch
Power switch to turn the power of the ESA-CXA on and
off. Be sure the controller is set to the “OFF ” position
when connecting actuators.
Caution
Do not insert or remove actuator connectors
while power is on. Amplifier damage may result.
2. Voltage adjust knob
The DC voltage can be adjusted with the 10-turn
potentiometer and is limited from approximately 10 to
160 volts. Since voltage may be present at the output
connector on the controller, do not probe this area with
any conductive material.
3. Voltage display
The LED readout display shows the voltage output to an
actuator which is set by the voltage adjust knob (2) for
X, Y, or Z axis.
