FM TRANSMITTER OMB EM 5000 HE DIG

The OMB 5KW EM 5000 HE DIG PLUS transmitter has been created by the OMB development center for high efficiency transmitters. It consists of the high efficiency 5KW amplifier, FMA 5000 HE, with an efficiency of 72% 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 time due to its low consumption. This 5KW FM transmitter is also available in Dual Drive version.

MAIN CHARACTERISTICS OF THE 5KW FM TRANSMITTER MADE BY OMB:

– AC efficiency: 72% (typical value). RF RF Efficiency: 84% (typical value)
– 6 1000W amplifier modules with MOSFET technology
– 3 independent switching power supplies connected in parallel so that if there is a failure in any of them, the equipment maintains its operation
– TFT screen and touch keyboard for the control and visualization of operating parameters.
– Event log in memory
– Speed ​​control of the cooling fans based on the temperature in the power modules to optimize electricity consumption and reduce noise pollution
– Advanced protection against load misadjustments without interrupting transmission and ultra-fast protection in the event of excessive reflected power and input power
– Analog telemetry, remote control and RS232 digital telemetry, remote control by open / closed contacts
– Low-pass filter, EMI filters and internal single-phase transient suppressor
– Automatic power reduction at night if the amplifier is combined with the EM 25 DIG PLUS
– Automatic power reduction in case of high temperature, the equipment automatically returns to its nominal power value when the temperature reaches 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 to optimize efficiency
– Optionally TCP / IP telemetry, SNMP, web server
