Features

  • Bipolar and unipolar output load
  • Galvanic separation of the output
  • Adjustable input range and phase inversion
  • Full stroke driving capability for benders (bimorphs), stacked actuators, bipolar stacks, shear mode actuators.
  • Low noise.
  • Small unified dimensions.

Purpose

The NDR6110 series piezo actuator driver is intended as the basic device that enables to supply various piezoelectric actuators with static and dynamic voltage in the range up to ±100V or 0-200V. The driver can be used as a part of fine adjustment mechanism in mechanical positioning equipment with piezo feed, or for other piezo element applications.

Description

The driver has a built-in voltage converter, so that only a single external supply voltage is needed. The device is supplied by the +5V/1A stabilized adaptor. The adaptor is included. The driver input signal can be static or dynamic.

It can be supplied by a potentiometer, trimmer, frequency generator, or D/A converter. The input range can be switched between ± 2.5, ± 5, 0 to 5, 0 to 10 Volts. The gain of the amplifier can be switched to negative (opposite phase). An internal voltage limiter guarantees output voltage within limits during operation and also during startup or shutdown. The actuator is protected against overvoltage or reverse voltage and subsequent depolarization.

The output of the device is galvanicly separated from other circuits. The following voltages are connected to the pins of the output connector: +U, -U, zero Volts, and output. This allows for connecting all categories of piezoelectric actuators.

The NDR6110 series drivers are available in a broad range of versions: with a potentiometer instead the input connector, DIN rail mounting casings, and OEM printed boards. Option is a bipolar asymmetrical output voltage (i.e. -30 to +150 V).
