Trek Model 30/20A High-Voltage Power Amplifier The Model 30/20A is a DC-stable, high-voltage power amplifier featuring an all solid-state design for high slew rate, wide bandwidth, and low-noise operation. t is configured as noninverting with a fixed gain of 3000 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. 0 to ±30 kV DC or peak AC 0 to ±20 mA DC or peak AC Greater than 550 V/ps DC to greater than 2.5 kHz 3000 V/V Key Specifications • Output Voltage Range: • Output Current Range: • Slew Rate: • Large Signal Bandwidth (2% distortion): • DC Voltage Gain: Typical Applications Include • Dielectric studies • Electron beam ion traps and ion sourcing • Electrospinning • Electrostatic deflection (including ion beam steering) • Electrostatic flame control • Electrostatic levitation • Electrostatic precipitation • High-voltage cable testing • High-voltage component testing • Plasma studies (including dielectric barrier discharge) 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 • CE compliant (230 VAC unit only) TREK, INC. • 190 Walnut Street • Lockport, NY 14094 • USA • 800-FOR TREK 716-438-7555 • 716-201-1804 (fax) • www.trekinc.com •
