OMB FM TRANSMITTER EM 6000 HE DIG

The new OMB 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 >70% 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. It is also available the Dual Drive version.

NEW FMA 6000 HE MAIN FEATURES

– Typical AC efficiency of >70%. Typical RF efficiency of 76%
– 2 amplifying stages with 4 amplifying modules of 900W with MOSFET technology each
– Each amplifying stage contains 3 independent switching power supplies connected in parallel for maintaining the operation of the equipment in case of failure of any of them
– TFT screen and touch keyboard for the control and visualization of operation parameters
– Memory recording of events
– Speed control of cooling fans according to the temperature of power modules for optimizing the consumption and decreasing the 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 failure of one of the power supplies and in case of excessive reflected power
– Automatic voltage control for efficiency optimization
– Optionally Telemetry TCP/IP, SNMP, Webserver
