PTD11 DC Supply System for Communication

The system is composed of AC distribution unit, rectifier modules, DC distribution unit, micro-processor based monitor module and battery, featuring high automation, small size, complete functions and high reliability.

1.     Technical features

í  Novel structure with good looking

The cubicle adopts blocky arrangement with easy fix and removing of face/side board or rear door, easing greatly the installation and maintenance. The face board is assembled with 19’ (19 inch) standard boards,

í  Wide range of voltage input

The range of AC voltage input is 90-290V(phase voltage), so the equipment is able to adapted in where the power grid is not so stable.

í  Two AC accesses interlocked each other ensures safety and reliability

The two AC inputs interlock with each other both electrically and mechanically to improve the system’s safety and reliability of running.

í  Character LCD display and digital settings

The system is equipped with a monitor module, whose LCD displays various system information in Chinese or English characters, the system parameter can be set digitally by the monitor easily and accurately

í  Reliable rectifier modules

The DMA14 type rectifier module features small size, wide range of voltage input, high efficiency, stable & reliable and convenient maintenance.

í  Acoustical and optical alarm with character display

When there occurs a fault during the running of the system, the monitor module will make an alarm acoustically and optically with the fault content displaying on the LCD of it.

í  Intelligent manage on battery

   The monitor module is capable of adjusting the charge mode, charge voltage/current of the battery based on the parameter of its capacity and ambient temperature. Furthermore, in the case that the battery discharge voltage is underdue, the battery will be cut off automatically.

í  Four remote functions

The equipment can be connected with upper system via  RS485/232 interface or modem, realizing the functions of remote communication, remote metering, remote adjusting and remote controlling, namely the four remote functions.
