High Voltage Power Amplifiers
Model PZD350A
Trek Model PZD350A Piezo Driver/Amplifier
Superior Bandwidth Capabilities
The Trek Model PZD350A is a high-voltage DC power amplifier designed to provide precise control of output voltages in the bipolar range of 0 to ±350 V and unipolar ranges of 0 to +700 V or 0 to -700 V DC or peak AC.
Output current ratings are ±200 mA for the bipolar range or ±100 mA for the unipolar ranges. Bipolar or unipolar ranges are customer specified and factory set. The Model PZD350A is configured as a noninverting amplifier with a variable DC gain to 150 V/V. An inverting amplifier configuration is optionally available. Features include an all-solid-state design, a slew rate greater than 500 V/µs (±350 V range) or 350 V/µs (700 V ranges).
"DC to greater than" bandwidth capabilities for the 350 volt range include large signal bandwidth of 250 kHz (-3 dB) and a small signal bandwidth greater than 350 kHz (-3 dB).
Applications for the Model PZD350A include piezoelectric driving/control, laser modulation, semiconductor research, and ion beam control.
A 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 PZD350A is available in single channel or dual channel instruments and can be operated on a bench top or, with optional hardware, in a standard 19-inch rack.
