INTEGRATED TELECOM POWER UNIT ITPU 2008AIntegrated Telecom Power Unit is an all-in-one power solution for Mobile Telecom Operators. It houses all required power and control equipments except Diesel Generators and Batteries in one 19 Inch Rack. The basic building block used is 25 Amp SMPS Rectifier as per latest TEC specifications. These rectifier modules have been designed to work in Indian electric and climatic environment and provide full power over applicable voltage and temperature range without any degradation in performance. The system gets electric power from two sources, a three phase commercial electricity connection and a single phase or three phase Diesel Generator. Using intelligent phase selection and distribution techniques, adequate numbers of Rectifier Modules are powered for providing DC power up to 3 BTS and forcharging the back-up batte ry. DG is put ON automa tically in case no good phas e ofMains Power is available and installed battery has discharged to the programmed threshold. The SMPS Rectifiers operate over a wide voltage range (90-300V Single Phase) eliminating the need of any additional Line Conditioning Unit (LCU), SVR orServo Stabilizer for powering the BTS. Provision is made for metering the energy consumed by each BTS. Required measurements, controls and alarm processing are done through Micro-processor based Control Modules. All required equipments including rec tifiers for ultimate c apacity of300A are accommodated in a 19” Rack of height 1660 mm.
