The 1140LA reflects E&Is commitment to reliable and robust RF power.
Flexible Operation:
The 1140LA produces 1000 Watts of quasi linear class AB power over a frequency range of 10 kHz to 2 MHz, with a nominal power gain of 55 dB (±1dB). Operation over the entire frequency range is possible without the need for any switching. Operation up to 5 MHz is achieved with a lower power gain.
The front panel display provides simultaneous measurements of forward and reflected power as well as the units status. The RS232 connector at the rear of the unit can also be used to capture this data and reset the unit should a fault occur.
The E&I 1140LA is a 19 rack mount unit 8U high. It employs an integral power supply capable of operation from 120 - 240 VAC 50 60 Hz. The unit weighs approximately 108 lbs or 48 Kg.
