Technology talking to the environment
An Intelligent Power House of Performance
The smart alternative to conventional AC Diesel GeneratorACME 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.
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, space-
consuming, 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 10-15 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 20-25 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 High-efficiency alternator The ACME DC Power House
uses a proprietary alternator
design that uses a permanent
magnet and no rotating
parts that wear out. There
are no bearings, couplings,
brushes, slip-rings or
rotating fields. The alternator
efficiency is as high as 91%
as compared to 75-80% in
the case of conventional AC
generators.
Remote fuel Level Monitoring ACME DC Power house has electronic fuel level
sensor which monitors fuel level continuously. It is
highly accurate ( 2-3%)Fuel level data is available
on LCD as well as on RS485 comport for remote
monitoring, which helps in controlling fuel theft.
Fuel savingACME DC Power House can reduce fuel consumption
by 30-40 percent compared to a conventional AC
Diesel Generator. A conventional AC generator is
designed to run at fixed RPM and gives best fuel
efficiency when loaded at 80 percent or more,
whereas ACME DC Power House runs at variable
speeds to match the load, thus consuming less fuel at
part loads. Fuel saved is money earned.
Zero conversion lossesWith a conventional AC
generator, SMPS is required to
convert AC to DC. This results
in conversion losses of 10-
15 percent. ACME DC Power
House provides 48V DC that
can be directly used by telecom
loads such as BTS and battery,
so there is no conversion loss.
Power saved is power earned.
Telecom grade DC Power Ripple & Psophometric Noise are very important
& Critical parameters for SMPS or any other DC
Source used for Telecom Load & Battery. ACME
DCPH offers very low ripple (i.e. <300mv Pk – PK
without Battery and <100 mv Pk-Pk with Battery)
& Psophometric Noise (<4mv) and it complies with
TEC specifications.
Compact and lightweightCompared to a conventional
AC Diesel Generator, ACME
DC Power House is almost
half in weight and size, and
so needs much less space. It
is truly a little wonder.
High automation with com portACME DC Power House is equipped
with RS 485 communication port
that provides connectivity for open
protocol. The data from this port
can be sent to the NOC through
the server, which helps in the real-
time site monitoring of various
parameters. ACME also provides this
facility at its state-of-the-art GEMC
(Global Energy Monitoring Centre)
located at Gurgaon, India. Real-time
monitoring helps you stay proactive.
No power theftAt a telecom site powered by a conventional AC Diesel
Generator, it is common for power to be stolen for
domestic use. Since ACME DC Power House delivers
output as DC, which can’t be used for any domestic
applications, there is no chance of power theft.

hour (KWh) and run-hour
meter, amongst others.
Environment adaptabilityACME DC Power House
withstands a variety of
adverse situations like rain,
temperature variations,
damp heat, salty atmosphere
and vibration. An all weather
friendly product.
Tamper-proof metersTelecom operators suffer losses due to the
malfunction or tampering of the hour and KWh
meters. Keeping this in mind, ACME DC Power House
is equipped with tamper-proof electronic hour and
KWh meters. No one can penetrate this fortress.
11
Easy installationACME DC Power House can be installed very easily,
especially compared to a conventional AC Diesel
Generator. For instance, there are no lengthy wires or
complicated connections to be done with the PIU.
12
Quiet operationCompared with a conventional AC Diesel Generator,
ACME DC Power House operates at a far lower
noise level of 67 dB at 1 meter. It is truly a silent
performer.

Scalability with convenient parallelingTwo or more ACME DC Power House can be
connected in parallel together, irrespective of the
model. The appropriate power capacity and number
of paralleling units can be selected to meet disparate
loads. A truly scalable machine.

About ACME
*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.
