High-current High-voltage Wideband Linear Power Amplifier for Underwater Communications
Technical Parameters:
The L6 is a wideband linear power amplifier capable of delivering high current and high voltage; it functions as a high-power, high-frequency sinusoidal power source and can drive resistive, capacitive, and inductive loads. Featuring comprehensive protection functions, stable performance, and high reliability, the product is widely used in fields such as underwater acoustic communication, electrochemistry, and wireless power transfer. Thanks to its outstanding performance and reliable quality, it has become standard equipment for underwater acoustic communication research at major defense research institutes and laboratories at marine-focused universities.
The L6 linear power amplifier offers a -3dB bandwidth of 100 Hz to 100 kHz and an RMS output voltage of up to 1012 V. It delivers a continuous output power of 800 W and a pulse output power of up to 2000 W. The output stage provides eight selectable impedance settings to facilitate matching with loads of varying impedances. The L6 is equipped with robust protection features, ensuring automatic protection and fault status indication in the event of a blown fuse, input overvoltage, output overcurrent, or internal overheating.
