ATA-700 Series High Voltage Amplifier

Output from 2kVp-p up to 20kVp-p (±10kVp), Bandwidth (-3dB) up to DC~25kHz, Output current up to 40mAp

Kilovolt-level drive covers a wide range of high-voltage applications. Aigtek's ATA-700 Series addresses it with high-voltage amplifiers that amplify both AC and DC signals, with single-ended output from 2kVp-p (±1kVp) on the ATA-701 up to 20kVp-p (±10kVp) on the ATA-710.

Bandwidth and current trade off against voltage across the range: the ATA-701 reaches 25kHz with up to 40mAp, while the ATA-710 delivers 20kVp-p at up to 1.2kHz and 2mAp. This suits voltage-driven loads such as capacitive and dielectric test loads, which typically draw modest current even at high voltage.

The ATA-703, ATA-705 and ATA-710 provide four-quadrant output, voltage and current monitor ports for real-time oscilloscope monitoring, status indicators, and output enable via a rocker switch with BNC or TTL control.

Frequently Asked Questions

How do I choose a model within the ATA-700 series?

Start from the voltage, bandwidth and current your load needs. Maximum voltage ranges from 2kVp-p (ATA-701) to 20kVp-p (ATA-710), with bandwidth and current decreasing as voltage increases: from 25kHz and 40mAp on the ATA-701 to 1.2kHz and 2mAp on the ATA-710.

What does the ATA-700's output current range mean for the loads it can drive?

Maximum output current ranges from 40mAp on the ATA-701 to 2mAp on the ATA-710. These ratings suit loads that are primarily voltage-driven rather than current-hungry; capacitive and dielectric test loads typically draw modest current even at high voltage.

How is the high-voltage output enabled and monitored?

On the ATA-703, ATA-705 and ATA-710, the high-voltage output is controlled by a rocker switch together with a BNC enable input that also accepts TTL control, and dedicated voltage and current monitor ports allow real-time oscilloscope monitoring of the output.
