HCT-10K is the top power Analog TV transmitter for National TV station.
l Combined amplification design, ready for digital.
l Dual exciter configuration with automatic switchover.
l High gain power amplifier modules. The transmitter does not need low power drive stage. The exciter is directly connected to power amplifier.
l MOSFET power amplifiers with high redundancy.
l Modular design, hot plug-in replacement, easy maintenance and short MTTR.
l Excellent versatile power amplifier modules available for 1KW to 20KW transmitter.
l High reliability, multiple protections and long MTBF.
l Multiple remote interfaces including remote measurement, control, communication, adjustment, and LCD display for major fault and operation conditions.
l Based on microprocessors, which facilitate remote control operation. The control system offers intelligent adjustment for transmitter’s optimum operation (DG, DP, IM, ICPM, etc).
l Switch mode regulators connected in parallel, each one can be hot plug-in and on-line maintenance.
l Network interfaces and software (optional).
l Force air-cooling system.
l Centrifugal blower inside.
