TREK Product - Model 603 Power Amplifier / Piezo Driver

Trek Model 603 Power Amplifier/Piezo Driver

Now equipped with SHV type high-voltage output connectors.

The Trek Model 603 is a DC-stable, Power Amplifier / Piezo Driver designed to provide precise control of output voltages in the ranges of 0 to ±125 V, 0 to -250 V, or 0 to +250 V DC or peak AC. The output current capability is 0 to ±40 mA DC or 0 to ±80 mA peak AC for all voltage ranges. The Model 603 features an all solid-state design for high slew rate, wide bandwidth, and low-noise operation. The four-quadrant, active output stage sinks or sources current into reactive or resistive loads throughout the output voltage range. This is essential for achieving the accurate output response and high slew rates demanded by reactive loads. Industrial applications using the Model 603 include driving piezoelectric actuators, modulating electrooptics, and electrostatic deflection.

The Model 603 is protected against overvoltage and overcurrent conditions generated by active loads or by output short circuits to ground. Precision voltage and current monitors provide 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 output of the instrument. This makes the Model 603 suitable for automated or computer controlled systems.

The Dynamics Adjust feature can be used to optimize the AC response of the output signal. The Model 603 Power Amplifier / Piezo Driver operates as a noninverting amplifier with a fixed gain. The input gain can be programmed for 25 V/V or 50 V/V. Consult the factory for information on reprogramming the factory set output configuration.

The Model 603 comes from the factory with settings for an output voltage of ±125 V DC or peak AC and a signal gain ratio of 50 V/V. The Model 603 is available in single or dual channel configurations.
