ATA-M Series Power Amplifier
Output up to 690Vrms and 800VA, Bandwidth (-3dB) 10kHz-500kHz, drives 0-100% resistive or non-resistive loads
Driving a load that isn't a clean, fixed resistance — anything from a partially reactive test load to a device whose impedance shifts across its operating range — needs an amplifier that can adapt its output impedance matching rather than assuming a fixed, purely resistive load throughout. Aigtek's ATA-M Series addresses this directly: a single-channel amplifier built to drive loads across the full 0-100% resistive-to-non-resistive range, with output impedance matching adjustable via multiple taps.
Maximum output voltage of 690Vrms and 800VA output power give the ATA-M substantial drive capability, with bandwidth spanning 10kHz to 500kHz (-3dB) covering a solid mid-to-high frequency range for demanding load-driving applications. Built-in protection against over-temperature, over-voltage, short-circuit and no-load conditions adds a layer of safety for test setups where load characteristics may not be perfectly predictable in advance, with the protection status shown on the LCD.
The adjustable impedance matching taps let a test engineer configure the amplifier's output matching to suit the specific load being driven, rather than accepting a fixed matching configuration that may not be optimal across every load type the amplifier is asked to handle.
