DPM Series FM Exciters

DPM FM Transmitter 30W to 5000W

NEW ECO-FRIENDLY COLLECTION, GREEN RF FM TRANSMITTERS


GREEN RF is the evolution of the COLD FET™ technology updated with the latest LDMOS devices. Offers High Efficiency and 65:1: VSWR Rugged capacity. Constructed totally in aluminum to prevent corrosion and reduce the heavy (AAD), mount a High Efficiency Redundant Cooling System (HERC), this features reduce the energy consumption, increase the reliability, reduce room heating, space occupied and specifically reduce the maintenance.


MAIN CHARACTERISTICS


• Available Output Power: 30, 50, 100, 150, 300, 500, 1.000, 2.000, 3.000, 5.000, 10.000, 15.000, 20.000, 30.000 and 40.000W
• All the models share the same human interface.

• AAD Technology: the construction is totally in aluminum. The air is ducted to reduce the electronic boards‘contact. The electronic boards are tropicalized with a special resin to protect the circuits against salt air. All this prevents the corrosion produced by the air and increase the reliability.

• The microprocessor is protected against short main interruption with external Watch Dog and dedicated Power Supply Supervisory.

• Input sensitivity and output deviation are adjustable with high precision of 0,05dB trough display interface or remotely by WEB.

• TCP/IP Remote control WEB Server SNMP (v2 and v3), with INFORMS, DHCP, FTP, TELNET. The IP and the other network parameters can be easily read and set on the front panel.

• Firmware remotely upgradable by TCP/IP, an easy procedure is on the WEB interface without the needing to use proprietary tools; the received software is controlled with a check-sum; after new release has been installed it's possible to return to the previous firmware release installed; from WEB / SNMP it's possible to select which release (the new or the old one) will run on air.

• Memory and recall of 10.000 working parameters pre-settings. The parameters of each station on the network can be memorized like: name, frequency, audio settings, alarms settings, etc.

• Modulation monitor generate alarms or warnings with programmable level thresholds and time for any audio and auxiliary inputs.

• Overal Electrical Efficiency 65% Typical 70%

• STEREO GENERATOR: High performance built-in digital stereo generator with 65dB separation, 85dB signal/noise ratio ensures top audio quality.

• AES/EBU digital interface.

• Limiter keeps the maximum frequency deviation within international requirements to avoid over-modulation and adjacent channels invasion.

• Uninterrupted service: intelligent protection circuit reduces proportionally the output power staying on-air in case of over-temperature or high VSWR. All this functions can be enabled or disabled by software.

• N+1 facility control available to modify remotely the frequency and power output for redundant systems.

• High Efficiency Switch-Mode Power Supply with Power Factor Control, meets all the international requirements for mains network disturbances.

• Over-dimensioned cooling system keeps the heat sink to 15°C above ambient temperature to properly operate even in high ambient temperature sites with hard climate conditions.

• Very small dimensions and low weight, reduce transport costs and simplifying the logistic.

• Meets or exceeds all the international standards for safety and electrical specifications.
