Overview

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 reflects E&I’s commitment to reliable and robust RF power.

Flexible Operation:

The 1140LA produces 1000 Watts of quasi linear class B power over a frequency range of 9 to 2,000 KHz, with a nominal power gain of 55dB (+/-1dB). Operation over the entire frequency range is possible without the need for any switching. Operation up to 1 MHz is achieved with a lower power gain.
The front panel display provides simultaneous measurements of forward and reflected power as well as the unit’s 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 at 115 or 220 VAC, 50 – 60 Hz. The unit weighs approximately 95 lbs or 45 Kg.
