Model PZD700 M/S Piezo Driver/Amplifier

Now equipped with a SHV type high-voltage output connector.

The Trek Model PZD700 M/S amplifier system provides precise voltage control and delivers twice the current of our standard Model PZD700. The PZD700 M/S is a high-voltage DC power amplifier with an available bipolar voltage range of 0 to ±700 V and unipolar ranges of 0 to +1.4 kV or 0 to -1.4 kV DC peak AC. Output current capabilities of ±200 mA for the bipolar range and ±100 mA for the unipolar ranges are available. Voltage ranges and input configurations (inverting or noninverting) are customer specified and factory set.

Applications for the PZD700 M/S include piezoelectric driving/control, laser modulation, semiconductor research, and ion beam control. Features include an all-solid-state design, a slew rate greater than 200 V/µs for the ±700 volt range, a slew rate greater than 150 V/µs for either the 1.4 kV ranges, and a small signal bandwidth of greater than 100 kHz for all voltage ranges. The four-quadrant active output stage sinks or sources current into reactive or resistive loads throughout the output voltage range. This capability is essential for achieving the accurate output responses and high slew rates demanded by reactive loads.

Precision voltage and current monitors provide buffered low-voltage representations of the high-voltage output and load current for monitoring purposes or for use as feedback signals in a closed-loop system. The Digital Enable feature provides a connection for a remote device to turn ON and OFF the high voltage of the instrument. The Model PZD700 M/S has a Dynamics Adjustment feature which is used to optimize the AC response of the output for various load configurations.
