Power amplifier ATA-703

currentvoltagemeasuring

Product overview
The ATA-703 is a high-voltage amplifier designed to amplify both AC and DC signals. It provides four-quadrant operation up to 6 kVp-p (±3 kVp) and is suitable for driving high-voltage loads. The wide-range power supply supports global mains voltages for laboratory and industrial use.

Key features

• Bandwidth (-3 dB): DC–5 kHz
• Output voltage: 6 kVp-p (±3 kVp)
• Maximum output current: 15 mAp
• Power: 45 Wp
• Slew rate: ≥67 V/μs

Status display
Status LEDs indicate Power On, High-Voltage Operation and Overcurrent conditions for clear operational feedback and troubleshooting.

Output control
The high-voltage output is controlled by a rocker switch combined with a BNC enable input. Local operation: connect the BNC shorting cap to enable the output; remove the cap to disable. TTL control: 0 V–3.3 V (low level, 3.3 V excluded) = ON; 3.3 V–5 V (high level) = OFF.

Monitor

• Voltage monitor (1 mV/V): BNC port for real-time output voltage measurement (oscilloscope)
• Current monitor (100 V/A): BNC port for real-time output current monitoring

Fixed gain
The voltage gain is fixed at ×1000 for consistent signal scaling.

Applications

• Dielectric and piezoelectric actuation
• Electro-optic modulation
• Material polarization and plasma research
• Withstand voltage testing and electrostatic deflection
• Particle accelerator and mass spectrometer applications
