The 2KW FM transmitter, EM 2000 HE HOT PLUG, has been created by the OMB center of development for high efficiency transmitters. It consists on the high efficiency 2KW amplifier, FMA 2000 HE HOT PLUG, with >73% efficiency and the EM 25 DIG PLUS, a 25W FM exciter/transmitter. The high efficiency 2KW amplifier has an approximate consumption of 2600VA at 230Vac, so it pays for itself in a short period of time due to its low consumption. This 2KW FM HOT PLUG transmitter is also available in Dual Drive version.

MAIN FEATURES OF THE 2KW FM TRANSMITTER MANUFACTURED BY OMB:

– Typical AC efficiency of >73%. Typical RF efficiency of 84%
– 2 amplifying modules of 1000W with MOSFET technology
– 2 independent switching power supplies connected in parallel for maintaining the operation of the equipment in case of failure of any of them
– TFT screen and touch keyboard for the control and visualization of operation parameters
– Memory recording of events
– Speed control of cooling fans according to the temperature of power modules for optimizing the consumption and decreasing the acoustic contamination
– Advanced protection against load mismatches without transmission cuts and fast protection in case of excessive reflected power and/or excessive input power
– Analog telemetry, digital remote control and telemetry RS232, remote control by opened/closed contacts
– Low pass filter, Mains 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 returns automatically to its rated power value when the temperature reaches back an average value
– Automatic power reduction in case of failure of one of the power supplies and in case of excessive reflected power
– Power supplies of the amplifier are hot removable and interchangeable
– Automatic voltage control for efficiency optimization – Optionally Telemetry TCP/IP, SNMP, Webserver
