ATA-703 High Voltage Amplifier

Product catalog summary

Introduction
The ATA-703 is a high voltage amplifier designed for amplifying both AC and DC signals. It offers a four-quadrant output with a maximum voltage of 6kVp-p (±3kVp) and can drive high-voltage loads. It supports a wide-range power supply for global compatibility.

Status Display
The device features indicator lights for Power On, High Voltage Operation, and Overcurrent to display its operating status.

Output Control
The high-voltage output is managed via a rocker switch and a BNC enable interface. In local operation, connecting the BNC shorting cap turns the output ON, while removing it turns the output OFF. In TTL control, a low level (0V~3.3V) turns the output ON, and a high level (3.3V~5V) turns it OFF.

Monitor
The amplifier includes a 1mV/V port for voltage monitoring and a 100V/A port for current monitoring, both connectable to an oscilloscope for real-time monitoring.

Fixed Gain
The voltage gain is fixed at x1000.

Applications
The ATA-703 is suitable for applications such as Dielectric Material Actuation, Piezoelectric Actuation, Electro-Optic Modulation, Material Polarization, Plasma Research, Withstand Voltage Test, Electrostatic Deflection, Particle Accelerator, and Mass Spectrometer.

Xi'an Aigtek Electronic Technology Co., Ltd. ATA-703 High Voltage Amplifier  Bandwidth (-3dB): DC~5kHz  Maximum Output Voltage: 6kVp-p (±3kVp)  Maximum Output Current: 15mAp  Slew Rate: ≥67V/μs  Short Circuit Protection, Over Current Protection and Current Limiting Output INTRODUCTION The ATA-703 is an ideal high voltage amplifier capable of amplifying both AC and DC signals. It features four-quadrant output with a maximum voltage of 6kVp-p (±3kVp), and can drive high-voltage loads.The wide-range power supply accommodates different regional power standards worldwide. STATUS DISPLAY The status indicator lights (Power On, High Voltage Operation, and Overcurrent) clearly show the device's operating status. OUTPUT CONTROL The high-voltage output is controlled via a rocker switch in conjunction with a BNC enable interface. BNC enable status description (rocker switch in ON position). Local Operation: When the BNC shorting cap is connected, the device output is ON; when the shorting cap is removed, the device output is OFF. TTL Control: 0V~3.3V (low level,3.3V excluded) → the device output is ON; 3.3V~5V (high level) → the device output is OFF. MONITOR 1mV/V Monitor: This port is for voltage monitoring and can be connected to an oscilloscope for real-time monitoring of the output voltage. 100V/A Monitor: This port is for current monitoring and can be connected to an oscilloscope for real-time monitoring of the output current. FIXED GAIN The voltage gain is fixed at x1000.
