ESA-C In Stock

The ESA-C by Newport is an Ultra-Resolution Actuator Controller meticulously crafted to seamlessly integrate with compatible electrostrictive actuators featuring a specialized micrometer-style bezel. Specifically designed to complement the ULTRAlign stage, this controller offers precise control over output voltages upon insertion of the output DIN-connector. In the absence of connector engagement, the voltage is maintained at a steady 0V, with axis voltage parameters constrained within the 10 to 160.6 V range. Operating versatility is a hallmark of the ESA-C, which functions adeptly in both remote and local operational modes. A notable feature is its IEEE-488.2 compliant GPIB interface, enabling standardized communication.

The ESA-C preserves manual adjustment capabilities unless a remote mode command is issued by the GPIB controller. The inclusion of a front-panel knob facilitates direct adjustment of DC voltage, accounting for inherent controller tolerances. The ESA-C's voltage, set through the potentiometer or IEEE interface in remote mode, is presented on the LCD display across its X, Y, and Z axes. Display accuracy is maintained at a resolution of 0.1 V, equivalent to approximately 0.02 µm. A distinctive attribute is the output voltage at the monitor BNC, pegged at 1/20 of the applied voltage, permitting direct connection to an oscilloscope for voltage monitoring. This configuration proves invaluable when dealing with AC signals combined with DC voltage, albeit with an inversely proportional reduction in maximum allowable AC amplitude as frequency escalates.

The ESA-C incorporates a HIGH BW LED indicator, signaling a frequency response exceeding 30 Hz at 20 volts peak-to-peak. Accompanying this is the high bandwidth mode controlled by the rear panel DIP switch positions. This controller is also equipped with an AUX BOARD LED, illuminating when an internal option board is present. A REMOTE LED is indicative of GPIB software-induced remote mode, which temporarily suspends front panel controls. If adjustments are enacted on the front panel while in REMOTE mode, the actuator will revert to LOCAL mode based on altered knob positions. For precise positioning, the ESA-C accommodates rear-panel analog inputs, which, when combined with front panel settings, determine the final position. Tolerances for higher frequencies are lowered to enable functionality, with a ≤ 20 Hz bandwidth attainable when coupling the system with an ULTRAlign positioning stage and electrostrictive actuators.
