OMB FM TRANSMITTER EM 10000 HE DIG (5KW+5KW)

The OMB 10KW FM transmitter, EM 10000 HE DIG PLUS, has been created by the OMB center of development for high efficiency transmitters. It consists on the high efficiency 10KW amplifier, FMA 10000 HE, with >70% efficiency and the EM 100 DIG PLUS, a 100W FM transmitter. The high efficiency 10KW amplifier is composed by two 5kW amplifying stages (FMA 5000 HE) and has an approximate consumption of 14.2KVA at 230Vac, so it pays for itself in a short period of time due to its low consumption. This 10KW FM transmitter is also available in Dual Drive version.

MAIN FEATURES OF THE 10KW FM TRANSMITTER MANUFACTURED BY OMB:

– Typical AC efficiency of >70%. Typical RF efficiency of 80%
– 2 amplifying stages with 4 amplifying modules of 1.000W 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
