The new EM 3000 HE DIG PLUS has been created by the OMB center for the development of high efficiency transmitters. It consists of the FMA 3000 HE power amplifier which has 72% efficiency and the new EM 25 DIG PLUS transmitter.
This 3-3.5kW amplifier has an approximately consumption of 4200VA @ 230Vac, so it can be amortized in a short period of time due to its low consumption. It is also available the Dual Drive version.
NEW FMA 3000 HE MAIN FEATURES
- AC Efficiency: 72% (typical value). RF Efficiency RF: 84% (typical value)
- 4 amplifying modules of 900W with MOSFET technology
- 3 independent switching power supplies connected in parallel so 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 operational parameters.
- Memory registration of events
- Control of the speed of cooling fans depending on the temperature at the power modules for optimizing power consumption and decreasing acoustic contamination.
- Advanced protection against load mismatches without interrupting the transmission and ultra-fast protection in case of excessive reflected power and input power.
- Analog telemetry, digital RS232 remote control and telemetry, remote control by opened/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 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.
- Automatic voltage control for efficiency optimization.
