YE5879 5 channel 2500VA digital power amplifier
YE5879 power amplifier is a digital power amplifier. This power amplifier can be used to drive the exciter as a high-power excitation source for vibration testing and vibration measurement. Can be widely used in aviation, aerospace, machinery, construction and transportation departments of vibration research and vibration experiments.
Digital power amplifiers are similar to DC - DC switching inverter circuits. The input analog signal is modulated by the PWM circuit to form a pulse chain with a duty ratio proportional to the input signal. After amplification by the switching circuit, the high-frequency component is filtered by a low-pass filter to restore the amplified signal waveform Output.
