Introduction:
LFPA 9733B is a low-frequency power amplifier produced by Schwarzbeck, Germany, and authorized by EUTTEST in Shenzhen, China. It is especially suitable for low-frequency magnetic field immunity testing according to ISO 11452-8, and it replaces the NFPA 9730, which has been discontinued.
The amplifier can have a gain effect of 26dB in the frequency range of 5Hz-1MHz (nearly 20 times amplification), external two banana head power output port, can directly output large voltage and current signals to theHomer Hertz antennaand handheld radial ring antennas to generate a magnetic field, the voltage and current are shown by a display on the front of the unit and an overvoltage and overcurrent alarm is provided.
