The 500W FM amplifier FMA 500 HE is the result of the OMB development centre for high efficiency amplifiers. It has an efficiency of >73% and an approximate power consumption of 750VA at a voltage of 230Vac, so that in a short period of time the equipment is amortised thanks to its low power consumption.

High efficiency amplifier FMA 500 HE, solid state mosfet technology with switch-mode power supply with 90 – 250 V input and internal transistor suppressor. The following parameters are displayed on a colour graphic display with touch sensor:

Direct power
Reflected power
Measurement of the 600 W RF module
Source voltage
Power module temperature indication
Digital, analogue and contact telemetry
Alarms against temperature, SWR, over excitation, direct power over current and power supply.
FOLD-BACK (automatic gradual power reduction in case of SWR).
Power reduction in case of excessive ambient temperature
Adjustable power from 0 to 500W
Low-pass filter and EMI mains filter included.
