5000W FM transmitter

    SKU EM 5000 HE DIG Categories ,


    The 5KW FM transmitter, EM 5000 HE DIG PLUS, has been created by the OMB center of development for high efficiency transmitters. It consists on the high efficiency 5KW amplifier, FMA 5000 HE, with >73% efficiency and the EM 25 DIG PLUS, a 25W FM transmitter. The high efficiency 5KW amplifier has an approximate consumption of 6600VA at 230Vac, so it pays for itself 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

    – Typical AC efficiency >73% and typical RF efficiency of 84%.
    – Six amplifying modules of 1.200W with robust LDMOS transistors of the latest technology.
    – 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 25 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.
