The 1140LA Amplifier is a rugged source of RF power for ultrasonics, induction heating and laser modulation as well as plasma applications. It is a totally solid state solution employing RF DMoS FETs in the power amplification stages, offering simultaneous forward and reverse power readouts, and RS232 port for data collection. The 1140LA produces 1000 Watts of quasi linear Class AB power over the entire frequency range from 10 KHz - 2 MHz.
