FM TRANSMITTER OMB EM 7500 HE HOT PLUG

35.990,00

The OMB 7.5KW transmitter, EM 7500 HE HOT PLUG, has been created by the OMB development center for high efficiency transmitters with hot plug modules. It consists of four high-efficiency 2KW amplifiers, FMA 2000 HE, with> 73% efficiency (can be used externally as 2KW amplifiers) and the EM 100 DIG PLUS, a 100W FM transmitter. The 7.5KW high-efficiency amplifier has an approximate consumption of 73% and a typical RF efficiency of 80%.

1000W amplifier modules with MOSFET technology.
– Power supplies connected in parallel to keep the equipment working 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.
– Analog telemetry, digital remote control and RS232 telemetry, remote control by open / closed contacts.
– Low-pass filter, network 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 automatically returns to its nominal power value when the temperature reaches an average value.
– Automatic power reduction in case of excessive reflected power.
– Automatic voltage control to optimize efficiency.
– TCP / IP, SNMP and Webserver are optiona
