1 ACME An Intelligent Power House of Performance DC Power House The smart alternative to conventional AC Diesel Generator ACME Tele Power Ltd. (ATPL) provides comprehensive passive infrastructure solutions to wireless telecom players, both in India as well as overseas. With a strong focus on R&D, ATPL has developed products that provide cost-effective, energy-efficient, integrated solutions to telecom companies. Unlike most competitors, we provide end-to-end solutions. The ACME DC Power House is a result of ATPL s pioneering R&D endeavours. It is designed to meet the changing power demands. It addresses this need by producing the DC current required to meet the exact power and speed requirement and ensures the intended load power supply even as the battery is getting charged. Technology talking to the environment

2 WHY DC POWER HOUSE? Energy-saving is being increasingly concerned around the world. Leading through innovations.. ACME is known in the industry for innovating new technologies and ideas and translating those into assured and big benefits for the actual users. Development of DC Power House is one more great effort of ACME in this direction. ACME has specially launched this solution for green energy - serving emergency power supply. With intelligent use of this innovative product of high efficiency, energy saving and environmental friendly, the running cost is greatly reduced. At Telecom site, when there is no utility power, the DC output of DCPH not only ensures the telecom grade power supply for the load but at the same time charges the battery and thereby meets the constant power demand for telecommunications devices. In the pursuit of excellence, this product has been conceptualized and engineered to address not only the optimum consumption of fuel (diesel) at varying loads but also in the process helps bridging the ever widening gap that exists between electrical power supply and demand in developing countries. Relative saving in fuel burning as compared to the conventional AC Diesel Genset results into considerable reduction in CO2 emission. With intelligent use of DC Power House, ACME also achieves its corporate mission Technology talking to the environment and also earns Carbon Credits. Concept and Technology of DC Diesel Generator has evolved out of following facts: >> Offers the cheapest and most efficient of all Back-Up-Power solutions >> Specially designed variable speed engine consumes fuel with varying load conditions unlike conventional AC Diesel Gensets >> AC DGs waste fuel while operating at partial loads as engine runs at fixed speed only >> Most conventional AC Diesel Gensets are heavy, spaceconsuming, noisy machines. Run at constant RPM irrespective of load applied, they consume higher amounts of fuel resulting in poor fuel efficiency. >> In a conventional AC generator, SMPS is required to convert AC to DC. This results in conversion losses of percent. It provides 48V DC that can be directly used by telecom loads such as BTS and battery, thereby removing any loss in conversion. >> MTBF & operational reliability of DC Diesel Gensets better than ACDG s >> For telecom network penetration into rural areas having little or no-grid availability, initial investment for other back-up power solutions like Solar, Wind, etc. too high >> Has brought to limelight several benefits over ACDG s (refer table at other page) >> AC Gensets runs at percent of their rated capacity during the initial years, leading to more consumption and emissions. This is a drain on the operational expenditure of the operator, and is also energy-inefficient and unfriendly to the environment. >> Shift of power from AC to DC results into considerable saving on CAPEX & OPEX >> DCPH has provision to integrate with Network Monitoring System (GEMC) designed and installed at ACME HQ (Gurgaon, India). Unique features offered include: remote real-time access, monitoring and control of various parameters (load, alarms, fuel consumption, break down action taken report/closure, MTTR, MTBF, Billing, tracking of Preventive maintenance schedule, spares tracking, DCPH auto start /stop, etc

7 Vision About ACME Being the global benchmark for At ACME, our philosophy is to envision and develop technologies green energy solutions. that not only make great economic sense in terms of acceptability, efficiencies and return on investment, but also have a lasting Mission impact on social well-being. We firmly believe, that any technology Making the Green Approach profitable. we develop has to be socially rewarding, through augmenting and enriching the environment. Our principal idea is to make the green approach financially rewarding. *ACME Rudrapur, India factory An intelligent way of lowering Carbon Footprints and Earning Carbon Credits A Diesel Generator when run for around 8 hrs at a tower site, results in the consumption of around 16 litres of Diesel per day and 6,000 litres a year. This would mean a CO2 emission of 15 tons per year for a single tower. For 330,000 existing towers in India, CO2 emmissions per year stand at 5 Million tonnes. By using DCPH in Place of ACDG, carbon emissions can be reduced by 30% i.e. to 3.5 Million tonnes per year. This means added benefits in terms of carbon credit and its earnings. Overall, ACME DC Power House reduce fuel bills, helps earn carbon credits and contributes to a green environment.
