ATA-L Series Power Amplifier

Output current monitor 100mV/A, output voltage monitor 10mV/V or 5mV/V depending on model, BNC monitor connectors for oscilloscope

Some test setups need a power amplifier that combines genuinely wide bandwidth with substantial output power and the flexibility to drive both resistive and non-resistive loads — a combination that's harder to achieve than any single specification in isolation. Aigtek's ATA-L Series is built as a wide-band single-channel amplifier capable of high power output, adaptable across the full 0-100% resistive-to-non-resistive load range.

Built-in output current and voltage monitoring — 100mV/A for current and 10mV/V or 5mV/V for voltage, depending on the model — gives a direct, real-time readout of what the amplifier is actually delivering to the load, accessible via a BNC monitor connector for connection to an oscilloscope. This monitoring capability matters for applications where verifying the actual delivered signal, not just the commanded output, is part of the test requirement.

The combination of wide bandwidth, load flexibility, and built-in monitoring makes the ATA-L a practical choice where a test setup needs to both drive a demanding load accurately and independently verify what's actually reaching that load — rather than trusting the amplifier's output setting alone.

Frequently Asked Questions

What's the benefit of built-in current and voltage monitoring with an oscilloscope connector?

Rather than needing a separate current probe or voltage measurement setup to verify actual amplifier output, the BNC monitor connectors provide that readout directly at known scaling (100mV/A for current; 10mV/V or 5mV/V for voltage depending on the model), simplifying the test setup and giving real-time visibility of the delivered signal.

How does the ATA-L compare to the ATA-M series?

Both drive 0~100% resistive and non-resistive loads, with output impedance matched across selectable ranges and built-in voltage and current monitoring. The ATA-L covers lower frequencies (from 40Hz or 200Hz up to 120kHz or 150kHz) and higher voltage and power, up to 1200Vrms and up to 6500VA (ATA-L50), while the ATA-M covers 10kHz to 500kHz at up to 690Vrms and 800VA.

Why does wide bandwidth matter for a general-purpose load-driving amplifier?

A wide bandwidth means the same amplifier can accurately drive test signals across a broader frequency range without needing to switch to a different, frequency-specific instrument — useful in applications where the test signal's frequency content spans a wide range or where the same amplifier needs to serve multiple test types.
