DTU-52 Series ：
High-Power Liquid-Cooled Digital UHF TV Transmitter
NEC transmitter equipment is renowned for High Reliability and Low Maintenance throughout the global broadcast community. The DTU-52 Series inherits the technological and performance advantages of the previous DTU-51 Series, which through many years of field operation, has been highly praised by our customers, and has successfully achieved two additional advantages; high efficiency and small footprint.
Features
| Enhanced Efficiency
With the new PA, the DTU-52 Series enables a reduction in power compumption by an average of 20 to 30% compared to the previous model. |
User friendly monitoring and control
Control and monitoring of the equipment is carried out via the colour LCD on the front of the rack which features an intuitive Graphic User Interface for easy maintainability. As an example, it is possibile to monitor IM and MER without the use of measuring equipment. |
| Small Footprint
The DTU-52 Series provides up to 8.7kW output power (average) by using 10 sets of PA units in a single rack, achieving a footprint of only 590 (W) x 2,000 (H) x 1,000 (D) mm, making it one of the smallest transmitter foot-prints in the world. |
Wide range of redundancy configuration
To meet customer's ever increasing demands, the DTU-52 Series can offer wide range of backup options: from redundancy only in the liquid cooling system to N+1 configurations. |
| Advanced cooling system
With the adoption of Hybrid Closed System for cooling, there is the advantage of excellent cooling liquid exchangeability and automatic removal of air from the system when an amplifier is changed. |
Wide band design
The DTU-52 Series is designed to be frequency-agile, covering the entire UHF band and thus, no channel-specific components are required. |
| Compliant to a variety of digital terrestrial broadcasting standards
The DTU-52 Series is able to support a wide range of global digital standards including ATSC, DVB-T/H, ISDB-Tb, and the latest established standard - DVB-T2. |
Reduced maintenance costs
All DTU-52 Series transmitters are produced from, and supported by, one common set of modules, resulting in reduced costs from purchase to installation and suppport. |
