Power converters for telecom

Powertec Supplies India offers dedicated power converters for telecom. It has come out with SMPS units of COSEL, Japan and Artesyn Technologies, USA enclosed in various modular packages to suit customer applications. These SMPS units as well as DC/DC converter modules are enclosed in standard modular aluminium/steel enclosures and provided with screw connectors or suitable quick connect/disconnect and weatherproof interconnections. The modular enclosures are plug-in-module (PIM) for card cage assemblies or instrument case for stand alone laboratory models. For 19" standard rack enclosures employed with various networking applications, these supplies are housed in 1U/2U/3U/6U height panels with 84T width and a depth of 200/300/400 mm as required. The European standard (ETSI) racks with power supply outputs are readily available as per consumer requirements. Special DC/DC converters are fabricated for customer requirement of CDMA/WLL and other multiplexers. These range with Input 48 V DC (32-75 V DC) and generate 5 V DC, 12.5 V DC, 24 V DC or 28 V DC as desired for the equipment. The input/outputs are isolated and floating to 3000 V DC. Power levels could range from 100 W to multiple kilowatts. The configuration desired for communication systems could be dual redundant for current sharing operation or hot swap for repair removals while the second unit is functioning. The current capacities range from less than an ampere to 100 A. The voltages are generally 48 V DC floating. However the company is capable of providing up to 350 V DC generated from AC mains.
