FM TRANSMITTER OMB EM 500 HE DIG

3.990,00

The OMB EM 500 HE DIG transmitter has been created by the OMB development center for high-efficiency transmitters. It consists of the high efficiency 500W amplifier, FMA 500 HE, with> 73% efficiency and the EM 25 DIG, a 25W FM transmitter. The high-efficiency 500W amplifier has an approximate consumption of 700VA at 230Vac, so it pays for itself in a short time due to its low consumption.

MAIN CHARACTERISTICS OF THE 1KW FM TRANSMITTER MADE BY OMB:

– Typical AC efficiency 75%. 84% typical RF efficiency
– TFT screen and touch keyboard for the control and visualization of the operating parameters
– Event log in memory
– Speed ​​control of the cooling fans according to the temperature of the power modules to optimize consumption and reduce noise pollution
– Advanced protection against load misadjustments without transmission outages and quick protection in case 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
– Optionally TCP / IP telemetry, SNMP, web server
