Bandwidth (-3dB) up to DC~1.2MHz, Output voltage up to 310Vp-p (±155Vp), Max output current 8Arms
Some high-voltage loads need substantial current and power as well as voltage. Aigtek's ATA-40000 Series covers this with high-voltage power amplifiers that amplify both AC and DC signals, delivering up to 1314Wp (ATA-40506B) and up to 11.31Ap, 8Arms output current (ATA-41008).
The ATA-41008 delivers 160Vp-p (±80Vp) and 905Wp with bandwidth to 1.2MHz, while the ATA-40506B delivers 310Vp-p (±155Vp) and 1314Wp with bandwidth to 500kHz. Both have N-type outputs, a 1/100 voltage monitor port, and finely adjustable voltage gain and DC bias.
Within Aigtek's range, the ATA-40000 is the higher-power step above the ATA-4000 series (up to 547.1Wp), for loads where current and power, not just voltage, are the limiting factor.

⬇ Download Datasheet (PDF) Enquire About ATA-40506B →The ATA-40000 offers substantially more power and current: up to 1314Wp and 11.31Ap, versus up to 547.1Wp and 5.65Ap for the ATA-4000. The ATA-4000 reaches further in bandwidth, up to 3MHz on the ATA-4315, versus up to 1.2MHz for the ATA-40000.
Fine DC bias control lets the output waveform's operating point be shifted independently of its AC gain, which matters for applications where the driven device needs a specific DC offset alongside its AC drive signal — piezoelectric and certain capacitive-load applications commonly need this kind of combined AC/DC control.
Above 50Hz the ATA-41008 delivers up to 11.31Ap (8Arms) and the ATA-40506B up to 8.48Ap (6Arms). This matters for loads that draw significant current at high voltage, rather than presenting a purely capacitive, low-current characteristic.
