The
Silcon DP300E series saves money and protects the environment
|
|
Over a five-year
period, the savings you'll enjoy with a DP300E are quite amazing.
Changing to the DP300E series should save enough in yearly power
consumption, to pay your new UPS within 5 years!
If you are buying
your first UPS the advantages are obvious- the DP300E savings on
the power bill will generate return on investment from day one.

The Environmental
Benefit
|
|
| The money you save
on your electric bill means you charge nature with less pollution
as you use less power and reduce the CO2 emitted from the power plant.
Furthermore, the DP300E systems are made of PVC free materials. In
the event of fire it does not generate halogen gases, and all components
are recyclable. |

Input
corrected power factor, plus no mains repercussion, and high efficiency
- all add up to green power
|
|
| The Silcon
DP300E power factor |
|
| The DP300E has a
power factor corrected input side ensuring that the input power factor
is always 1 regardless of load and mains voltage. A power factor of
1 minimizes installation costs by using smaller cables and smaller
fuses. |
|
| No mains
repercussions |
|
| In more and more
countries, power distributors are setting new restrictions on mains
distortion. Exceeding those standards can be very costly. Most UPS
systems have a problem with distortion of the utility mains. The distortion
is caused by the 6-pulse thyristor rectifier in the mains input circuit.
This distortion has to be eliminated (EMC requirements) by large filters,
which causes further decrease in efficiency. DP300E technology which
maintains a sinusoidal mains current, eliminates this problem and
meets the EMC requirements. |
|
| Small
heat losses |
|
| DP300E offers massive
savings not only in operating costs for the unit itself, but also
in air conditioning costs due to the very low heat losses from DP300E.
Lloyds Bank in London, for example, installed a 2.7 MW DP300E system.
The annual power savings from using a DP300E instead of an ordinary
UPS was estimated at $160,000. That figure will be even higher because
of additional savings in air conditioning. |

The
Silcon DP300E extends battery lifetime
|
| APC has long been
recognized as a leader in providing extended battery life. A unique
process called "float voltage compensation" achieves maximum
battery life. Charge voltage is regulated to compensate for battery
temperature. With no compensation, battery life decreases, as temperature
increases. By adjusting the charging voltage by very small amounts
(typical compensation levels range from 2.20 to 2.36 volts/cell),
battery life is extended as seen in the green curve. |
|
| Extra
safety with Advanced Battery Monitoring (ABM) |
|
| Batteries are an
extremely important part of the UPS. ABM continuously compares actual
battery data to preprogrammed data in the monitoring software to ensure
DP300E batteries are healthy and ready. Any reduction in battery capacity
triggers alarms automatically. |
