Three reasons why
DENYO Power GENERATORS set the standards in performance,
quality and user- friendliness.
REASON 1
Denyo is a specialized generator
manufacturer that relies on its own patented
technology and design. The result of this effort
is the DCA Series soundproof generator range,
which have features and flexibility built into
each generator that other makers/assemblers cannot
match. At this very moment, Denyo is continuing to
develop new technology for tomorrow's power needs.
REASON 2
All Denyo generators are designed and
manufactured in order to provide full power
performance and are rated on the alternator's
actual capabilities. In addition, Denyo utilises
engines that can sustain our alternator's 100%
load rating.
Other brands of generators publish and market
their generator's output ratings based upon their
alternator's maximum output, which totally
disregards alternator and engine efficiency loss.
Therefore on paper, these generators may appear
powerful in relation to price.
In contrast, Denyo's manufacturing concept means our generators
will outperform other brands in terms of effective
performance and life-time operating costs.
Users around the world can rely on the fact that
Denyo generators will perform according to what is
written on the generator's nameplate.
REASON 3
The Total Quality control system employed
in each of Denyo's three factories ensures each
generator is thoroughly tested during the various
phases of production. Each completed generator,
before delivery, is then subjected to a full
range of tests as prescribed by Denyo's Code of
Manufacturing.'' This comprehensive quality
control system, plus the test card issued with
each generator, is Denyo's
guarantee to you
that each generator will perform as described
herein.

GENERAL CONSTRUCTION
 The
DCA Series generators are complete, stand- alone
generating sets. All models consist of a Denyo
alternator which is directly coupled to a diesel
engine. The alternator and engine are set on a
common skid base. Special vibration isolatora are
used to minimise vibrations during operation. The
generator and electrical components are fully
enclosed in a solid-steel, weather- proof canopy.
Noise suppression is achieved
using highly
effective sound insulating
materials.
DENYO'S ADVANCED
BRUSHLESS GENERATOR
DESIGN: The patented brushless generator is a
rotating- field, self-ventilated, single-bearing,
4-pole synchronous alternator complete with damper
(amortisseur) windings for minimal voltage
deviations and to minimize the generator's effect
on magnetic/radio waves. This unique design
ensures minimum waveform distortion, minimum
reactance and maximum efficiency, which produces
high-quallity electricity.
EXCITER: Brushless rotating exciter, 3-phase
full wave rectifled with silicon diodes, designed
for maximum motor starting.
ROTOR: With fitted pads and windings',
dynamically balanced and permanently aligned to
the engine by flexible disc coupling.
COOLING: Direct-drive centrifugal ventilating
fan, for ample air flow and noise suppression. |

PERFORMANCE
FEATURES
HIGH-PERFORMANCE:
The Denyo generating system guarantees the
following levels of performance:
TEMPERATURE RISE: IOO'C temperature
rise at 40'C ambient (JEC 114).
INSULATION: Class F (JEC 114).
VOLTAGE REGULATION: Within
±
1 .5% for
DCA-I3SP to
DCA -150SP; within
±
1.0% for DCA- 180SP to
DCA-8OOSP.
(except SCA-800SSA-M)
FREQUENCY REGULATION: Within 5.0%
through no- load to full-load.
VOLTAGE WAVEFORM: Deviation Factor of
open-circuit terminal voltage does not exceed
0.06.
Telephone Influence Factor (TIF) is less than
50.
ELECTROMAGNETIC INTERFERENCE LEVEL:
Attenuated to meet most commercial
requirements.
INSULATION RESISTANCE: Higher than 3
Mega-ohms, measured between armature windings
and earth, field windings and earth, field
control circuit and earth.
DIELECTRIC STRENGTH: All winding
insulation can withstand voltage of 50 or
6OHz, and minimum 15OOV for one minute.
The innovative excitation systems fitted on
all models, in conjunction with the AVR and
advanced brashness generator, provides fast
voltage regulation in response to load
variations, enabling use soon after startup.
This system provides output stability during
load variations.
*U.S Patent No. 4268788 Synchronous
brushless alternator for minimal wear.
Designed to function in all climatic
conditions.
Will safely power the most sensitive loads,
such as thyristors, invertors and computer
systems, without the risk of damage to these
loads, thanks to the high level electrical
characteristics of the generator's output.
ECONOMICAL PERFORMANCE
Easy starting and quick response.
Utilising highly reliable diesel engines with
low fuel consumption, manufactured by Japan's
leading engine manufacturers.
Uninterrupted generator operation for up to 12
hours under full load.
UNSURPASSED FLEXIBILITY
To meet today's varying needs successfully,
your equipment must be as flexible as you are.
The Denyo DCA Series generator range provides
you with the flexibility to get the job done
simply and economically, without any delays.
True HEAVY-DUTY PERFORMANCE
For a particular job, you may need that extra
power from your generator. With the DCA
Series, the standby power rating 110% or 105%
load) can be used continuously for 1 hour in
every 8 hours of continuous operation. This
extra power performance of Denyo generators
means you can get the job done, without the
inconvenience of using another generator.
PARALLEL OPERATION FEATURE
(optional for DCA-35 to DCA-90SP)
From time to time, at a construction site,
mine site or in other situations, a large
temporary power supply is required for a
particular job. To meet this requirement
Denyo's DCA Series generators incorporate a
built-in parallel operation drive system,
allowing you to create a large-capacity
generating plant on-site, without the need to
procure any other equipment.
DUAL VOLTAGE SYSTEM
(optional for DCA-25sp to DCA.90SP)
For companies that operate internationally or
have motors that require power at different
voltages, a different generator is usually
required for each voltage setting.
However, the DCA Series generators are
equipped with a dual voltage system, so one
generator can be used to power motors with
different voltage settings. An extremely
convenient feature.
ALL MODELS CAN RUN AT 50 Hz/60 Hz
Simply adjust the engine speed on the control
panel to use a DCA Series generator at either
50 Hz or 60 Hz.
EXTREMELY QUIET OPERATION
In urban areas and at the worksile, there is
an ever increasing demand for reduced noise
pollution. In response to these concerns,
Denyo has pioneered a soundproof and super
soundproof range of generators. The DCA Series
generators are extremely quiet when operating
at full load, even though all soundproof
models are compactly designed. Check the
specifications for the sound level of each
model. |
