Linear Power Amplifier BAA 500 BEAK – 2. Generation

The analog power amplifier BAA 500 BEAK V4 230V was developed for the control of vibration test systems with a maximum of 500 VA. The RMS output power is calcu- lated at a load impedance of 4 Ohm. The frequency of the power amplifier at voltage mode ranges from 40 Hz to 25 kHz at full power or with DC to 200 kHz with reduced power and minimum harmonic distortion. The device offers extremely stable operation within the specified temperature and voltage range and is therefore highly reliable. The analog power amplifier allows operation in both voltage and current mode. Its RMS output current limit is variable.
