Xi'an Aigtek Electronic Technology Co., Ltd. AigtekATA-M4 Power Amplifier • Maximum Output Voltage: 345Vrms • Maximum Continuous Output Power: 400VA • Maximum Pulse Output Power: 1000VA, 10%@1S • Over Temperature Protection, Over Voltage Protection, Short Circuit Protection, and No Load Protection The ATA-M4 is an ideal single-channel power amplifier. It delivers a maximum output voltage of 345Vrms, continuous power of 400VA, and pulse power up to 1000VA. It is capable of driving 0~100% of both resistive and non-resistive loads. The output impedance is matched with multiple selectable ranges, allowing users to adjust according to specific testing requirements. The ATA-M4 features an LCD screen that dynamically displays device status and parameters. The user interface is intuitive, clear, and easy to understand, ensuring a user-friendly experience. Single-ended input with a BNC connector; the input signal's valid value must not exceed 1Vrms. Output Current Monitor: 100mV/A Output Voltage Monitor: 10mV/V The output monitoring port uses a BNC connector and can be directly connected to an oscilloscope for real-time monitoring. The output impedance is matched with multiple selectable voltage ranges. According to testing requirements, the output can be adjusted by setting the desired voltage percentage (0~100%) within the corresponding range. The device is equipped with protection features against over-temperature, over-voltage, short-circuit, and no-load conditions. The LCD panel displays the current protection status, and output can only resume after the fault has been cleared. Note: 1. The valid value of the input signal must not exceed 1Vrms. Adjustments within this limit may be made as needed for actual use. 2.During operation, the device must be used strictly within the specified bandwidth, maximum output voltage, and load limits. Over-range and no-load operation are strictly prohibited.
