The EM
1000 is a 1000W FM transmitter made up of the EM 25 DIG exciter
(or EM 20/30 exciter) and the AM 1000 FM amplifier. This
equipment includes 4 300W high-efficiency MOSFET-Technology amplifying modules. The output
power is externally adjustable from 0 to 1000W. Furthermore it includes LPF (Low Pass
Filter), telemetry output, it is microprocessor controlled and has a LCD display for the
visualization of the most relevant parameters: Forward and Reflected power, overdrive,
group currents, power supply voltage, SWR and temperature alarms. The cooling system is
based in a high-performance heat-exchanger which allows 4000m-height operation (12,000
feet). The switching power supply endures voltage variations between 190 and 250V. The
Wilkinson Coupling System between modules allows uninterrupted operation with 4, 3, 2 or 1
module, meanwhile the damaged modules are replaced easily and quickly. For this reason,
this is one of the most versatile equipment of the broadcasting sector. The complete
equipment is supplied in an 8-unit 19”standard rack. |

EM 2000 is a 2000W FM transmitter made up of the EM 25 DIG exciter (or EM 20/30 exciter) and the AM 2000 FM amplifier. AM 2000 includes eight 300W
high-efficiency MOSFET technology amplifying modules, fed by 2 independent switching power
supplies, which are made to withstand the working conditions. The amplifiying modules work
independently thanks to a power combining structure that provides high isolation between
them.The equipment includes a low-pass filter at the antenna output, EMI filters at the
utility connection and an internal transient suppressor. The LCD display shows the
amplifier main parameters: supply voltages, 8 module currents, direct, reflected and input
power, power loss in the internal unbalance load and three temperature sensors. The
amplifier control system stores in their memory all events and alarms detected, showing
time and date of occurrence. Smart temperature protection: if temperature
rises up to a level dangerous for the modules, the output power is reduced until the
temperature goes back to a “normal” state. If, even with the power reduction,
the temperature keeps on rising, then the amplifier is stopped until the temperature goes
down.Reflected power protection (load mismatch):
when the control system detects that the V.S.W.R. is dangerous for the modules, it reduces
automatically their output power so as not to exceed the internal security level. Besides,
there is a fast protection system that instantaneously turns off the modules polarization
when it detects a peak on the reflected power sensor. Automatic gain control: it reduces the gain in
the case of excessive driving power, keeping the adjusted output power despite temperature
changes. The control allows manual power adjustment by means of the front keyboard. |
