Switching Power Amplifier BDA 800 BEAK
The digital power amplifier BDA 800 was developed for the control of vibration test systems with a maximum of 810 watts. The RMS output power is calculated at a load impedance of 2.5 Ohm. The frequency of the power amplifier ranges from 20 Hz to 15 kHz at full power or with DC to 25 kHz with reduced power @ voltage mode. The device offers extremely stable operation within the specified temperature and voltage range and is therefore highly reliable. The digital power amplifier allows operation in both voltage and current mode. Its RMS output current limit is variable. (ACA)
