The ATA-4000 series is an ideal high voltage power amplifier that can amplify both AC and DC signals. With a maximum output voltage of 310Vp-p (±155Vp) and 547.1Wp power, it can drive high voltage power type loads. Voltage gain, DC bias NC is finely adjustable, providing customers with a wealth of test options.
ATA-4000 Series High Voltage Power Amplifier Application Scenarios: Ultrasonic Motor Drive, Soft Magnetic Testing, Non-Destructive Testing, Core Loss Testing, Driving Piezo Ceramics, Ultrasonic Transducers.
High-speed signal response
With a maximum bandwidth of up to 3MHz, the ATA-4000 series ensures high conversion rates and good step response of the signal.

Numerically controlled adjustable gain
ATA-4000 series breaks the traditional fixed gain multiplier, original numerical control gain adjustment function, the function can be directly on the amplifier multiplier X1, X0.1 step adjustment, suitable for all kinds of scientific research experiments that need to finely adjust the voltage.

Output DC Bias Adjustment
ATA-4000 series amplifier built-in DC bias adjustment function, can be set directly on the amplifier DC voltage superimposed on the AC voltage of the signal generator for output, and can achieve 1V, 0.1V refinement of the adjustment, so as to serve as the load side of the DC power supply change test.

quadrant output
When AC voltage is applied to capacitive or inductive loads, due to the load characteristics of the current and voltage signal phase of the existence of overrun or hysteresis, the current will be backed up from the load side, the general power supply or amplifier will not be able to drive the situation, the ATA-4000 series has a four-quadrant output characteristics, both the output current and the current can be absorbed, so that the series of products can be driven by various types of loads.

master-slave functionality
ATA-4000 series are single-channel output, when the experiment needs more channels synchronized output, you can choose this function. This function can cascade multiple amplifiers, set the parameters of the host, cascade the slave can be synchronized to make changes. Disconnect, but also be able to realize independent control.

short circuit protection
This function is suitable for scientific research experiments, the use of load power is not clear and lead to breakdown, the instrument will not have the risk of failure, can cut off the output in time. In general, only the overcurrent protection of the instrument, in this case, cut off in time, will lead to amplifier failure.
