FM TRANSMITTER OMB EM 4000 HE HOT PLUG

18.990,00

The OMB 4KW EM 4000 HE HOT PLUG transmitter has been created by the OMB development center for high efficiency transmitters with hot plug modules. It consists of two high-efficiency 2KW amplifiers, FMA 2000 HE, with> 73% efficiency (they can be used externally as 2KW amplifiers) and the EM 25 DIG PLUS, a 25W FM transmitter. The high-efficiency 4KW amplifier has an approximate consumption of 5450VA, so it pays for itself in a short time due to its low consumption. This 4KW FM transmitter is also available in Dual Drive version.

KEY FEATURES OF THE 4KW FM TRANSMITTER HOT PLUG MADE BY OMB:
– Hot plug modules.
– Typical AC efficiency> 73% and typical RF efficiency 80%.
– 1000W amplifier modules with MOSFET technology.
– Power supplies connected in parallel to keep the equipment running in case any of them fail. Hot-plug power supplies.
– TFT screen and touch keyboard to control and display the operating parameters.
– Record of events in memory.
– Speed ​​control of the cooling fans based on the temperature of the power modules to optimize consumption and reduce noise pollution.
– Advanced protection against load misadjustments without transmission outages and rapid protection in the event of excessive reflected power and / or excessive input power.
