  • Page 4: Section 2.0 Overview

    The MDT694 is a precision, low-noise, low-drift, high voltage controller for piezo actuators. The MDT694 provides both manual and external control of the piezo drive voltages. The MDT694 is an ideal driver for use with Thorlabs Piezo Actuators including the PE4 and the AE-series piezo elements. Typical applications include remote alignment of single-mode fiber couplers, remote positioning, Fabry-Perot etalons, etc.

    OUTPUT ADJ Knob – This knob will adjust the output voltage from 0 to 150V DC. It can also be used as an offset for any external input, since it is summed with the EXT INPUT BNC. POWER Button – Press in to turn the MDT694 on.

    1. Attach the piezo to the high voltage output connector on the MDT694 front panel. Note: the BNC center conductor is positive and the shield is at ground potential. Be certain to match piezo polarity to the connector since most piezo elements will be permanently damaged if connected backwards.

  • Page 7: Using The Ext Input Bnc

    Using the EXT INPUT BNC 1. Attach the piezo to the high voltage output BNC connector, located on the front panel of the MDT694. Note: the BNC center conductor is positive and the shield is at ground potential. Be certain to match piezo polarity to the connector since most piezo elements will be permanently damaged if connected backwards.

    A better approach would be to use an external encoder to give direct positional feedback. Section 6.0 Serial Interface (Optional) The MDT694 allows for an optional computer interface card to be installed. The rear panel DB9 connector will not be active unless the interface card is installed.

  • Page 9: Fuse Replacement

    Voltage Selector Switch will display the set operating voltage, either 115V or 230V) 4. Replace the fuse for the proper line voltage. The fuse rating is located on the rear panel of the MDT694 and in the Specifications section of this manual.
