Power: 2÷20W

PTRL-LCD

20W Radio Link TX 940÷960 MHz in step of 20 MHz factory limited. Please specify the operating frequency at the order.

FEATURES

PRIMARY APPLICATION: link to carry audio signals to support sound FM radio broadband broadcasting.

RADIO LINKS TOPICS: optimal price/performance ratio recognized worldwide.

AUDIO PERFORMANCE: low distortion and intermodulation values, combined with a high noise/signal ratio, provide high performance also together with an integrated stereo coder with L&R, Mono, MPX (composite signal) analog audio and auxiliary SCA/RDS inputs. The stereo coder is available as an option.

HARDWARE FEATURES: extremely compact and indeformable thanks to their stainless steel chassis, in 2 rack units (2HE) each only.

WORKING FREQUENCIES: standard working frequency bands is  200 ÷ 400 MHz and from 800 ÷ 960 MHz of 20 MHz and selectable in steps of 5kHz. Working frequency (hence, the frequency band) must be specified on order.

RELIABILITY/CONTINUITY: enhanced business continuit guaranteed in all working conditions through an APC automatic control and a Foldback protection. The presence a 24VDC connector connected to a battery or other power source ensures uninterrupted operation in the event of mains failure.

USER-FRIENDLY FEATURES: universal 80-260 V multi-voltage power supply enables operation on different mains voltages with no need to preselect voltage. Pushbuttons for user/device interaction provide enhanced accessibility, resulting in extreme ease of use. Configuration software offers a simple, intuitive interface.

INTERFACE CONTROL: total control thanks to microprocessor with all key parameters displayed on LCD.

EASE OF MAINTENANCE: advanced module engineering ensures extreme ease of access and simple maintenance.
