Emerson Ups Power Supply In Digital Cable Tv System
Emerson UPS power management solution for digital cable television system in the construction of
First, the traditional UPS power supply and environmental construction program required to meet higher demand
In the current digital broadcasting industry, the industrialization of the critical transition period, the broadcasting industry, new technology models and business models for the stability and security to run a higher requirement, also on the basis of all services and applications?? power and environmental systems building a more and more demands and new challenges. This performance was outstanding of which are digital cable television systems, the demand.
Digital Television Center (or IDC) engine room of the business is currently booming, the reliability of its power management solutions, security, maintainability needs to be improved greatly. Load in the engine room is mainly a variety of computers, servers, disk arrays and other loads. Construction of digital television system AC uninterruptible power supply systems (UPS) building on the following questions:
1) UPS power supply layout showing the status of decentralization, the exchange of electrical equipment after class to take power is not centralized;
2) UPS system, power supply scheme is irrational.
3) UPS variety, apart from the mainstream manufacturers, there are many small manufacturers products, good and bad.
4) UPS input and output system configuration showing a situation not entirely reasonable.
5) UPS status of the use and maintenance of a variety of reasons, it is not ideal.
Second, Emerson provided for the digital television system of power solutions
Based on the global forefront of technological superiority, Emerson Network Power Co., Ltd. for the broadcasting industry, providing a full range of digital TV system UPS power solutions, to make the program closer to the actual users, the UPS power supply system more reliable , more secure, easier to maintain.
Following a number of specific digital TV room in the program analysis:
1) Digital Television Broadcasting System in Guizhou center of a room configurations:
Configuration Program Analysis: The Radio and Television Information Network is the region where the largest company specialized information networks, broadcast television, digital television broadcasting in the overall translation front room 15 floor building, floor area of approximately 600 square meters. UPS power supply system in the engine room is crucial.
UPS power supply main to the main computer equipment to provide uninterrupted power supply. The program uses two series 40kUPS Emerson UL33 and machine operation widely used in the composition of the industry and the computer system 1 +1 redundancy, reliability is a single 5.5-fold.
Elements of the program: In today's broadcasting system, uninterrupted power supply system and other important room in order to ensure the load is not important because UPS, batteries, internal module system failure caused by power outages and other problems in the existing technical conditions, the use of " N +1 "redundancy-based UPS and Power Supply System is the best power supply to eliminate these failure program. It is the single UPS units to ensure the inverter output power in the same range, with the same frequency and phase conditions (single UPS in between the various "general circulation" equal to zero), the "N +1" Taiwan has the same output power of UPS put the output of single output state in parallel to run the power supply system. This advanced and the machine is much better than UPS, stand-alone program to run and run so hot backup mode.
With N +1 redundancy and machine power system reliability in the following areas:
1. To ensure that there is fail when a UPS is still able to provide continuous all load highly reliable power supply.
2. Redundancy and load electric machine system brought significantly improved the reliability of, and to such loads, the reliability of 99.999% or higher.
3. With the growth in customer business, expansion of the load device, the only existing and expansion machine system can, without the need to construct a new UPS power supply system, so the corresponding cost savings for customers and still maintain the power supply system reliability.
2) a broadcast system information Hangzhou Room Configuration options:
Configuration Third, the program summary In digital television broadcasting system, system construction and the use of N +1 redundant computer system that can provide customers with highly reliable power supply system, so the points for the parallel program and recommended indicators are as follows:
1, distributed directly parallel, UPS recommends direct parallel, without increasing, and the cabinet has built-in automatic bypass and maintenance bypass. User room to save space, reduce the purchase cost and ease of future expansion.
2, demands high standards of Parallel flow accuracy, enabling units, UPS loads are
