The 2KW FM transmitter, EM 2000 HE DIG PLUS, has been created by the OMB center of development for high efficiency transmitters. It consists on the high efficiency 2KW amplifier, FMA 2000 HE, with >73% efficiency and the EM 25 DIG PLUS, a 25W FM 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 transmitter is also available in Dual Drive version
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 excessive reflected power.
Automatic voltage control for efficiency optimization.
Power supplies of the amplifier are hot removable and interchangeable.
