TTek Model 40/15 High-Voltage Power Amplifier The Model 40/15 is a DC-stable, high-voltage power amplifier featuring an all solid-state design for high slew rate, wide bandwidth, and low-noise operation. It is configured as noninverting with a fixed gain of 4000 V/V and is protected against overvoltage and overcurrent conditions that may be 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 4-quadrant, active output stage sinks or sources current to reactive or resistive loads throughout the output voltage range. This is essential to achieve the accurate output response and high slew rates demanded by reactive loads. • Output Voltage Range: • Output Current Range: • Slew Rate: • Large Signal Bandwidth: (2% Distortion) • DC Voltage Gain: Features and Benefits • Four-quadrant output for driving capacitive loads • Closed loop system for high accuracy • Short-circuit protected for equipment protection • All solid-state design for maintenance free operation • DC-stable for programmable supply applications • Low output noise for ultra-accurate outputs • NIST-traceable Certificate of Calibration provided with each unit • C £ compliant TREK, INC. • 190 Walnut Street • Lockport, NY 14094 • USA • 800-FOR TREK 716-438-7555 • 716-201-1804 (fax) • www.trekinc.com •
