Product Description

1KW/3KW/5KW/10KW UHF/VHF All Solid-state Transmitter

The ELETEC transmitters family has been designed for broadcast analog TV standards(B/G, D/K, I, L, M, N colour coding standards SECAM, PAL, NTSC and sound coding standards FM mono or dual sound / stereo with optional coder.
This series is an air-cooled system available from low to high output power levels featuring excellent signal quality. Output power ranges are up to 32KW for VHF bI, VHF bIII & UHF frequency bands.
Each device is provided with high efficiency blowers ensuring a perfect cooling system. For the medium and high power systems the hot air is well extracted on the top of the cabinet. To obtain the required high output power, several independent base amplifiers are combined. It is possible to remove one or more amplifiers, for maintenance operation, without interrupting the service. The transmitter will be ever on air, at reduced power. Integrated latest LD-MOS technology guarantees excellent linearity and capability and also a high power level with compact design.
High efficiency switching power supply stages complete the great performance of  amplifier. High power transmitter is supervised by a main control unit which shows all system working parameters.
