  • Model: 30/20A
  • Manufactured by: TREK
  • Frequency Range - High: 20.00kHz
  • Output - Compression: n/a
  • Gain: n/a
  • Extra Specifications: High-Voltage Amplifier

The Model 30/20A is a DC-stable, high-voltage power amplifier designed to provide precise control of output voltages in the range of 0 to ±30 kV DC or peak AC with an output current range of 0 to ±20 mA DC or peak AC. The amplifier is configured as noninverting with a fixed gain of 3000 V/V. Inverting and differential input options are available. A calibrated potentiometer provides a DC offset over a range of 0 to ±30 kV DC.

Industrial and research applications include dielectric studies, electrostatic deflection, and electrooptic modulation.

The Model 30/20A 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.

The Model 30/20A 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 replicas of the high-voltage output and load current for monitoring purposes or for use as feedback signals in a closed-loop system. The Remote High Voltage Enable feature provides a connection for a remote device to turn on and off the high voltage of the instrument. This makes the 30/20A useful for automated or computer controlled systems.

The Model 30/20A-CE-H [180 to 250 V AC] is CE compliant.
