FM TRANSMITTER OMB EM 3500 HE DIG PLUS

10.990,00

The OMB 3.5KW FM transmitter, EM 3500 HE DIG PLUS, has been created by OMB development center for high-efficiency transmitters. It consists of the high efficiency 3.5KW amplifier, FMA 3500 HE, with an efficiency of 72% and the EM 25 DIG PLUS, a 25W FM transmitter. The high-efficiency 3.5KW amplifier has an approximate consumption of 4900VA at 230Vac, so it pays for itself in a short time due to its low consumption. This 3.5KW FM transmitter is also available in Dual Drive version.

MAIN CHARACTERISTICS OF THE 3.5KW FM TRANSMITTER MADE BY OMB:

– AC efficiency: 72% (typical value). RF RF Efficiency: 84% (typical value)
– 4 amplifier modules of 1200W 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 digital RS232 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
