Power amplifier 603

high-voltageDCfor piezo-electric actuators

The Trek Model 603 is a high-voltage DC power amplifier/piezo driver designed to provide precise control of output voltages in bipolar or unipolar ranges that are customer specified within a range of available settings. The instrument achieves the accurate output responses and high slew rates demanded by reactive loads by utilizing a four-quadrant active output stage that sinks or sources current into reactive or resistive loads. The Model 603 is configured as a non-inverting amplifier. An inverting configuration is optionally available. Both configurations are available in single or dual channel packaging. They are operable on a bench top or in a 19-in rack. Key Specifications Available Voltage Ranges: 0 to ±125 kV DC or peak AC 0 to -250 V DC or peak AC 0 to +250 V DC or peak AC Output Current Range: 0 to ±40 mA DC or ±80 mA peak AC for 1 ms Slew Rate: Greater than 100 V/µs Large Signal Bandwidth: DC to greater than 150 kHz (5% distortion) DC Voltage Gain: 50 V/V or 25 V/V Typical Applications Include Driving piezoelectric actuators Modulating electrooptics Electrostatically controlling ion beams Providing remote ON/OFF capabilities for automated or computer controlled systems Features and Benefits Four-quadrant output for driving capacitive loads Up to two independent amplifier channels in one enclosure Short-circuit protected for equipment protection CE compliant for assured reliability Reprogrammable factory-set output configurations All solid-state design for maintenance free operation Low output noise for ultra-accurate outputs
