Product Description

VHF TV AMPLIFIERS

VHF TV amplifier

The ED series is an excellent power TV amplifier system needed to increase transmission power. All ED series devices are composed by one or more AB class pallet amplifier stages (depends on output power required) based on 50V technology LD-MOS transistors characterized by higher power density, allowing very high levels of efficiency

Remote control interface
Strong mechanical structure
0 dBm RF monitor
Optional:
Hot swappable power supply
120 VAC input
EIA 7/8’’ output connector
Remote control
SNMP

They provide excellent values on key parameters of the transmitted signal quality, such as shoulder attenuation, MER and intermodulation value. A redundant power supply part architecture permits to these amplifiers to work at reduced power in case of failure of one or more power supply units. The following important features, built in, confer very high ruggedness and reliability to ED amplifiers: EMI filter on line voltage, switching power supply with PFC, fully redundant modular construction, control unit display, microprocessor controlled fans, SWR, over-temperature, over-drive, over-current and over-voltage protections. A display unit and USB port on frontal panel permit to control all operating parameters.
