X.DA-10
10 kW AM Transmitter10 kW AM transmitter from the X.DA series. Fully solid-state design with multiple redundant 1 kW power modules. HD Radio® (IBOC) and DRM compatible. Remote control via Ethernet built into the Control Panel board. Available in three-phase or two-phase 220 V configurations.
The X.DA-10 is a 10 kW solid-state AM transmitter designed for regional and national broadcasters operating at medium to high power. Its modular architecture groups twelve independent 1 kW power stages, simplifying corrective maintenance: when a module fails it is identified and replaced without specialist tools. Class D PWM modulation with HEXFET transistors delivers over 85% efficiency, substantially reducing operating costs over the transmitter's service life. The built-in Control Panel board provides Ethernet-based remote control and monitoring, and the unit is certified for HD Radio® (IBOC) and DRM digital broadcasting.
