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 isolators
are used to minimize vibrations during operation.
The generator and electrical components are fully
enclosed in a solid-steel, weatherproof, canopy.
Noise suppression is achieved using highly
effective sound insulating materials.
DENYO’S ADVANCED BRUSH-LESS
GENERATOR
DESIGN: The patented brush-less 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 wave-form distortion, minimum
reactance & maximum efficiency which produces high-quality electricity.
EXCITER: Brush-less rotating exciter, 3-phase
full wave rectified with silicon diodes, designed
for maximum motor starting. |

ROTOR: With fitted parts 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.

::
|
HIGH-PERFORMANCE |
The Denyo generating system
guarantees the
following levels of
performance:
|
 |
TEMPERATURE RISE: 100°C temperature rise at
40°C ambient (JEC 114).
|
|
|
INSULATION: Class F (JEC 114)
|
|
|
VOLTAGE REGULATION: Within ± 1.5%.
|
|
|
FREQUENCY REGULATION: Within 5.0 % through
no-load to full-load.
|
|
|
VOLTAGE WAVE FORM: Deviation Factor of
open-circuit terminal voltage does not exceed
0.06.
|
Telephone Influence Factor (TIF) is less than
50.
|
|
|
ELECTROMAGNETIC INTERFARENCE LEVEL: Attenuated
to meet most commercial requirements.
|
|
|
INSULATION RESISTANCE: Higher than 3
Mega-ohms, measured between
armature windings and earth, field control
circuit and earth.
|
|
|
DIELECTRIC STRENGTH: All winding insulation
can withstand voltage of 50 or 60 Hz, and
minimum 1500V for one minute.
|
|
|
The innovative excitation system* fitted on
all models, in conjunction with the AVR and
advanced brush-less generator, provides fast
voltage regulation in response to load
variations, enabling use soon after startup.
This system provides output stability during
load variations.
* US Patent No. 4268788
|
|
|
Synchronous brush-less alternator for minimal
wear.
|
|
|
Designed to function in all climate
conditions.
|
|
|
Will safety power the most sensitive load,
such as thyristors, invertors and computer
systems, without the risk of damage to these
loads, thanks to the high level electric
characteristic of the generator’s output.

UNSURPASSED
FLEXIBILITY
TRU HEAVY-DUTY
PERFORMANCE: For
a particular job, you may need that extra power
from your generator. With the DCA Series, the
stand by power rating 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.
50 Hz/60 Hz OPERATION: The DCA Series can be
operated at either 50Hz or 60Hz, by simply adjust
the engine speed using the throttle control knob
on the panel.
AUTO FULE AIR EXTRACTOR
Air trapped in the fuel system can be troublesome.
However, with the DCA Series, fuel air extraction
is automatically performed by simply operating the
starter switch, without other tools and devices.
There is no soiling in the machine’s interior or
the operator’s hands and the out flow of fuel to
the machine’s exterior is prevented. The machine
will start after the engine is turned over several
times.
ENVOIRMENTAL FRIENDLY
EXTREMELY QUIET OPERATION: In urban areas and
the worksite, there is an ever increasing demand
for reduced noise pollution. In response to these
concerns, Denyo has pioneered a sound proof range
of generators. The DCA Series generators are
extremely quiet when operating at full load, even
though all sound proof models are compactly
designed.
USE OF CLEAN ENGINES:
The engines use din
these generators meet the Californian Atmospheric
Pollution, which is one of the world’s most
stringent anti-pollution standards.
This is achieved by these engines using a PVC
(Purge Control Valve) system. Therefore, these
engines do not discharge blow-by gas to the
outside, which keeps the interior of the machine
cleaner and exhaust emission are minimized.
ECONOMILCAL PERFORMANCE
Easy starting and quick response.
Utilizing highly reliable diesel engines with low
fuel consumption,
manufactured by Japan’s leading
engine manufacturer.
Uninterrupted generator operation for up to 12
hours under full load.
MAINTENANCE MADE SIMPLER
All daily maintenance requirements can be
performed from one side of the machine. The large
doors give you full excess to the engine.
External drain plugs for oil, fuel and water are
fitted for convenience in performing routing
maintenance.
For major engine overhauls, the canopy (bonnet)
can be simply unbolted, which allows full access
to the engine.
