FM TRANSMITTER OMB EM 15000 HE DIG PLUS

51.990,00

The OMB 15KW FM transmitter, EM 15000 HE DIG PLUS, has been created by OMB development center for high-efficiency transmitters. It consists of the high efficiency 15KW amplifier, FMA 15000 HE, with> 70% efficiency and the EM 250 DIG PLUS, a 250W FM transmitter. The high-efficiency 15KW amplifier is composed of three 5kW amplifier stages (FMA 5000 HE) and has an approximate consumption of 21KVA, so it pays for itself in a short time due to its low consumption. This 15KW FM transmitter is also available in Dual Drive version.

MAIN CHARACTERISTICS OF THE 15KW FM TRANSMITTER MADE BY OMB:

– Typical AC efficiency of> 70%. 76% typical RF efficiency
– 3 amplifier stages with 6 amplifier modules of 1000W with MOSFET technology each
– Each amplification stage contains 3 independent switched power supplies connected in parallel to maintain the operation of the equipment in case of failure of any of them
– 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 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 100 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 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
