FM TRANSMITTER EM 6000 HE DIG

Description

The new EM 6000 HE DIG PLUS has been created by the OMB center for the development of high efficiency transmitters. It consists of the FMA 6000 HE power amplifier which has >73% efficiency and the new EM 100 DIG PLUS transmitter. This 6kW amplifier is composed by two 3-3.5kW amplifying stages (FMA 3000 HE) and has an approximately consumption of 8600VA @ 230Vac, so it can be amortized in a short period of time due to its low consumption.This transmitter can be supplied with the following options:
– Stereo generator
– RDS
– Web server/SNMP telemetry
– AES/EBU digital audio input

MAIN ADVANTAGES:
– Typical AC efficiency >73% and typical RF efficiency of 84%.
– Two amplifying units each composed by four amplifying modules of 1.200W with robust LDMOS transistors of the latest technology.
– Each amplifying unit contains three independent switching power supplies connected in parallel to maintain the equipment working in case any of them fails.
– TFT screen and touch keyboard to control and to visualize operation parameters.
– Memory recording of events.
– Speed control of cooling fans according to temperature of power modules so as to optimize consumption and to decrease acoustic contamination.
– Advanced protection against load mismatches without transmission cuts and fast protection in case of excessive reflected power and/or excessive input power.
– Analog telemetry, digital remote control and telemetry RS232, remote control by opened/closed contacts.
– Low pass filter, Mains EMI filter and internal single-phase transient suppressor.
– Automatic power reduction at night when used in combination with the EM 100 DIG PLUS transmitter.
– Automatic power reduction in case of high temperature, the equipment returns automatically to its rated power value when the temperature reaches back an average value.
– Automatic power reduction in case of excessive reflected power.
– Automatic voltage control for efficiency optimization.
