PD200X4 V2 Manual 3 Modified 13/01/2021
1 Introduction
The PD200X4 is a four-channel linear amplifier for driving piezoelectric actuators and other loads. The
output voltage range can be unipolar, bipolar, or asymmetric from 50V to 200V. Up to +/-200V can be
achieved using two channels with a bridged load. Refer to the specifications table for the available
output voltage ranges. Front panel switches and dedicated connectors for independent and bridged
loads make it easy to switch between four independent channels and two bridged channels with
double the voltage range.
The PD200X4 can drive any load impedance including unlimited capacitive loads such as stack
actuators; standard piezoelectric actuators; two wire benders; and three-wire piezoelectric benders
requiring a bias voltage. Bias voltages can be generated using two auxiliary outputs linked to the
power supply voltages, or by using an amplifier channel with a constant DC offset.
A range of user controls and ordering options are available to provide maximum application
flexibility. The DC offset of each channel can be controlled by a front panel potentiometer, or can be
fixed to zero as an option. The maximum positive and negative output voltages can be restricted
using two front panel potentiometers. A 15-pin DSUB connector on the front panel includes signals
for inputs, voltage monitors, current monitors, temperature measurement, a digital status output,
and a digital shutdown input.
The output connectors include BNC for independent channels, LEMO 0B for bridged channels, and a
plug-in screw terminal. The PD200X4 is suited to a wide range of applications including electro-optics,
ultrasonics, vibration control, nanopositioning systems, and piezoelectric motors.
