Denyo : Making a Difference on Worksites

Worldwide

We use electricity every day, taking it for granted. However, there are a surprising number ofsituations in which electricity supplied by the power company cannot be used or when there
is not enough electricity, such as on construction sites, during disasters, and in developing
countries. At such times, we supply as much electricity as is needed, whenever and wherever.
And we meet the expectations of customers around the world. Taking this as its mission, Denyo
has been working to develop better products ever since its foundation.

High-Performance
The Denyo generating system guarantees the following levels of performance
TEMPERATURE RISEINSULATION

100°C temperature rise at 40°C ambient (JEC2130*1).
Class F (JEC2130) or Class H (JEC2130)

VOLTAGE REGULATION

Within ±0.5% (except DCA-400SPKII & DCA-400ESK)FREQUENCY REGULATION

Within 5.0% through noload to full-load.

VOLTAGE WAVEFORM

Deviation Factor of open-circuit terminal voltage does not exceed 0.06.

ELECTROMAGNETIC
INTERFERENCE

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.
*1 Standard of Japanese Electrotechnical Committee

The innovative excitation system* fitted on all models, inconjunction with the AVR and advanced brushless generator,
provides fast voltage regulation in response to load variations,enabling use soon after start up. This system provides output
stability during load variations.
*U.S.Patent No.4268788

Parallel Operation Feature(Standard feature for DCA-125 to 800.)
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 theneed to procure any other equipment.

Dual Voltage System(Details are as per specification table.)
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.

Equipped with Electronic Governors(Details are as per specification table.)
Equipped with electronic governors that control the engine speed electronically, ourgenerators can maintain a constant RPM regardless of the amount of load applied(isochronous control*1). You can shift the control method to droop control if the purpose ofuse so requires, and you can control the speed using switches in a control box. *2*1 Generator from DCA-60USIE and above are set to droop control upon shipment from the plant.
*2 Only isochronous control mode is available for DCA-45USKE

from one side of the machine. The large doors give you fullaccess to the engine.
-For major engine overhauls, the bonnet can be simply
unbolted, which allows full access to the engine.

Output Terminal- Large fuel gauge is fitted for simple viewing.
- External drain plugs for oil, fuel and water are fitted forconvenience in performing routine maintenance.

Transportability-The new designs of the DCA Series range have achieved significant size and weight
reductions over previously producted models, through improvements in couplingtechniques and alternator design.
-The sturdy weatherproof steel bonnet on a heavy-duty steel skid
base allows easy handling by a forklift.
-The balance point lifting hook (lug) fitted on the roof of eachmachine facilitates easy transportation using a crane.
-All models are modular designed, so that generators can be stacked, thereby making
the best use of your valuable storage area.

Provision of Various Protective
Devices and Warning Lamps-A circuit breaker is provided to protect the generator fromshorting of the load circuit or an overload.
-An emergency stop device is provided to automaticallydetect an engine malfunction and shut down the unit aswell as a warning lamp.

ECO-BASE

Quiet Operation(DCA-25USIE/45USKE/25MZ/45MZ/60USIE)

Denyo’s generators run quietly thanks to the Company’s
original soundproofing technology. The Soundless Type &Ultra Soundproof Type in particular features a low-noiseengine, low-noise fan, the addition of a silencer, and special
structures such as changes to the hood shape, which createa low noise level similar to that of a quiet office.

ECO-BASE is a base which
has an oil receiver installedinside. You do not need to
put an extra tray on thebottom of generator. It is
designed to receive fuel, oiland coolant water when they
are discharged accidentally.

direction and connect external ducts
for installation location

Automatic Oil Lubrication Device(For DCA-35 to 1100, provided as standard feature for 610SPM and 1100SPM2)This system automatically maintains
engine oil at the proper level, making it
possible to reduce costs for oil-related
maintenance, and eliminates the needto check the engine oil level.

Automatic Start andStop Device
Available to start and stop a
generator remotely by externalsignals. Mainly used with the
combination of ATS (Automatictransfer switch).

Four-wheel type

(For DCA-75SP through 400)

Operation
MethodFully Automatic Parallel
Operation Device(with EASY GEN)

Manual Parallel Operation Device

Automatic Parallel Operation Device

Parallel operation system with unique Denyo AVR equippedwith a cross-current compensation circuit (CCR system).
This is the most inexpensive system and standard feature
for DCA-125 to 800.
For more secure operation in manual parallel mode, we
recommend "Reverse power relay " & "AC power meter" as
options.

The troublesome synchronization verification andsynchronization activation process can be automatically
performed by simply pressing a pushbutton. Aftersynchronization is activated, the Automatic Load Sharing
Device is capable of performing stable parallel operation.

Automatic Load Sharing Device

Fully Automatic Parallel Operation Device“EASY GEN”

This device operates a governor motor to share the load
uniformly among the respective generators when parallel
operation is being performed. It facilitates stable parallel
operation, and dramatically reduces the workload ofmonitoring during parallel operation.

High-speed digital control enables all operations fromstarting and stopping to synchronization verification,synchronization activation and load sharing to be performedat the touch of one button. This device has multiple
functions that enable parallel operation of generators withdiffering capacities, the number of units being operated tobe controlled and other operations.

EASY GEN 3500

Reverse power relay

AC power meter(For DCA-125 and above. Provided as standard feature for DCA-800, DCA1100SP,Automatic Load Sharing Device, Automatic parallel operation Device
and Fully Automatic parallel operation Device.)(For DCA-125 and above. Provided as standard feature for DCA-800, DCA1100SP, Automatic Load Sharing Device, Automatic parallel operation Device
and Fully Automatic parallel operation Device.)

In parallel operation, a reverse power relay will monitor
the direction of power for each generator, and when areverse power set up is exceeded, the breaker is tripped forprotection of relevant engine generator. (Recommended for
manual parallel operation.)

This is an indispensable instrument for monitoring the load
sharing and conducting the load transferring in parallel
operation. (Recommended for manual parallel operation.)

Motor usage examples in the above table are benchmark values : generator capacity will differ according to the required momentary voltage drop, motor loadfactor, and size of startup capacity, as well as motor age and efficiency

Notes- Momentary voltage drop when a motor starts up is assumed to be within 30% of no- load voltage.
- Motor startup kVA is assumed to be 7kVA per 1kW.
- Motor efficiency is assumed to be 85%, and load factor about 90%.
- Values shown for Y- startup(1) and Y- startup(2)are open and closed, respectively; needed generator capacity differs depending on startup state.
- Not appropriate for determining the capacity of emergency generating equipment (especially disaster-prevention generating equipment).
