The new Transmitter: EM 1K + 1K HE DIG PLUS, has been created by the OMB center for the development of high efficiency transmitters. It consists of the FMA 1K + 1K HE power amplifier which has 75% efficiency and the EM 25 DIG PLUS transmitter.
This 2kW amplifier is composed by two 1kW amplifying stages (FMA 1000 HE) and has an approximately consumption of 2600VA, so it can be amortized in a short period of time due to its low consumption. It is also available the Dual Drive version with automatic and manual switch system.
NEW FMA 1K + 1K HE MAIN FEATURES
- Typical AC efficiency of 75%. Typical RF efficiency of 84%
- 2 amplifying stages with 2 amplifying modules of 600W with MOSFET technology each
- 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 excessive reflected power.
- Automatic voltage control for efficiency optimization.
- Thanks to its redundancy the equipment keeps the transmission in case of failure of one of the amplifying stages.
