Delta Announces a New Telecom Power System: CPS 1500B Series High Efficiency DC/DC converter

Delta High Efficiency DC/DC Converter Helps Eliminate Tons of CO2 and Saves Carriers Millions of Dollars Annually

Taipei, Taiwan, Dec. 14, 2011- Delta Electronics, Inc., a world-leading power management solutions provider, announced its new CellD product series, featuring the CPS 1500B DC/DC converter, an advanced 1U converter power system. The new converter sets a new standard for energy efficiency and density for +24V/-48V and -48V/+24V dual voltage telecom power solutions. The new CPS 1500B performs power conversion with up to 95% efficiency, which is an outstanding 5-8% increase in energy efficiency compared to currently available models on the market This new standard for world class DC/DC density provides rack unit space savings of up to 83%, making the CPS 1500B a perfect solution for space critical applications.

“Delta is committed to our mission of ‘providing innovative, clean and energy-efficient solutions for a better tomorrow.’ Our latest CPS 1500B DC/DC converter is a milestone in energy efficiency for telecom power systems*. The Delta DC converters complete our InD and OutD systems to achieve total site power solutions globally.” said Kelvin Huang, head of the Telecom Power Solutions Business Unit at Delta Electronics.

The compact size and extended operating temperature range make this series suitable for both indoor and outdoor applications. Installation is easy as all Delta converters have connectors at the rear and are hot-pluggable. Fan cooling with speed control ensures near silent operation. Its compact footprint creates additional space that allows operators to install more revenue generating equipment. The low audible noise is an additional benefit for installing the CPS 1500B in urban areas.

“By combining this converter power system with Delta’s EnergE rectifiers, Delta provides unique energy efficiency for dual voltage power plants”, said Douglas Wilkins, product manager for telecom power solutions at Delta Greentech Inc. The significantly higher efficiency lowers the energy consumption required for cooling. Replacing existing average efficiency dual voltage power plants with this new converter series will provide OPEX savings of up to 1,500 USD annually per site. This is based on an average utility rate of 0.11 USD / kWh. It will also reduce annual CO2 emissions by up to 11500 tons for a network with 5000 sites.

*A note on telecom power systems
Telecom power systems secure telecommunication services in case of power interruptions or fluctuations. The essential parts of the system are rectifiers, batteries, and a power system controller. The rectifier converts alternating current (AC) to direct current (DC) and provides the power necessary to charge the batteries. The power system controller monitors and controls the entire system and site power infrastructure, maximizes battery life, supports energy saving and informs the operator of maintenance needs.
