OMB FM TRANSMITTER EM 1000 HE DIG

The 1KW OMB FM transmitter, EM 1000 HE DIG PLUS, has been created by the OMB center of development for high efficiency transmitters. It consists on the high efficiency 1KW amplifier, FMA 1000 HE, with >73% efficiency and the EM 25 DIG PLUS, a 25W FM transmitter. The high efficiency 1KW amplifier has an approximate consumption of 1300VA at 230Vac, so it pays for itself in a short period of time due to its low consumption. This 1KW FM transmitter is also available in Dual Drive version.

MAIN FEATURES OF THE 1KW FM TRANSMITTER MANUFACTURED BY OMB:

– Typical AC efficiency of 75%. Typical RF efficiency of 84%
– 1 amplifying module of 1000W with MOSFET technology
– 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 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
– Optionally Telemetry TCP/IP, SNMP, Webserver

Following options are factory fitted options and must be specified when ordering:

– Stereo generator
– RDS
