The 3,5KW FM amplifier FMA 3500 HE is the result of the OMB development centre for high efficiency amplifiers. It has an efficiency of >73% so that it pays for itself in a short period of time due to its low power consumption.

Solid state mosfet technology with three independent switching power supplies with 185-264V input and internal transient suppressor, microprocessor control and colour graphic display with touch sensor for the following parameters:

Direct power
Reflected power
Combiner temperature
Measurement of the individual currents of each of the 4 x 1,200W RF modules
Voltage at the 3 sources
Temperature indication at three points
Analogue, serial digital and contact telemetry
Alarms against temperature, VSWR, over excitation, direct power excess, over current and power supply failures
Automatic gain control
FOLD-BACK (automatic gradual power reduction in case of VSWR)
Power reduction in case of excessive ambient temperature
Adjustable power from 0 to 3.500W
Low pass filter included
