ATA-300 Series Power Amplifier

Max output power 4000Wp, Bandwidth (-3dB) DC~150kHz, Max output voltage 850Vp-p (±425Vp), Max output current 80Ap

Some power amplification applications need substantially more raw output power than a general-purpose amplifier provides — driving larger power-type loads, higher-current actuators, or more demanding test setups where thousands of watts, not hundreds, are the actual requirement. Aigtek's ATA-300 Series is built for this higher-power segment, amplifying AC and DC signals up to a maximum output power of 4000Wp.

Bandwidth to 150kHz (-3dB) is paired with substantial voltage and current capability — up to 850Vp-p (±425Vp) output voltage and 80Ap output current — giving the ATA-300 the combination of high voltage, high current, and meaningful bandwidth needed to drive genuinely demanding power loads. Numerically controlled voltage gain adjustment and one-click settings save keep this high-power capability accessible through straightforward, repeatable operation.

This power level positions the ATA-300 well above Aigtek's general-purpose ATA-3000 series (1000Wp) for applications where the load itself demands substantially more drive power — a distinction worth checking carefully given the similarity of the two series' naming.

Frequently Asked Questions

How does the ATA-300 differ from the similarly-named ATA-3000 series?

Despite the similar naming, the ATA-300 delivers substantially more output power (4000Wp versus 1000Wp) along with higher voltage (850Vp-p versus the ATA-3000's more modest range) and higher current (80Ap) — the ATA-300 is the higher-power option of the two, suited to more demanding load-driving applications.

What load characteristics does 80Ap output current support?

This level of current capability supports driving loads that draw substantial current at high power — larger actuators, higher-power test loads, or applications where the combination of high voltage and high current together (rather than either alone) is the actual requirement.

Why does one-click settings save matter at this power level?

High-power test setups often get reconfigured and reused across repeated test cycles, and being able to instantly recall a previously validated configuration reduces both setup time and the risk of misconfiguring a high-power setting, which carries more consequence at this power level than at lower power.
