• Dry Weight: Ranges from approximately 379 kg to 1180 kg

Performance and Features

• Voltage Regulation: Maintains within ±1.0% using Denyo's high-performance AVR for stable output.
• Waveform Distortion: Minimal distortion due to improved damper coil and generator design, suitable for sensitive loads like SCR, X-ray units, and computer backup.
• Sound Level: Sound-proof technology reduces noise below 65 dB(A) at 7 meters, classified as super low noise by Japanese Ministry of Construction.
• Low-Cost Operation: 4-pole generator design allows economical low engine speeds (1500-1800 rpm) and efficient 4-cycle diesel engines reduce fuel consumption.
• Breather System Engine: Prevents blow-by gas exhaust, keeping generator interior clean.
• Automatic Fuel Bleeding Device: Available on DCA-6LSX, 10LSX, 15LSX models; automatically releases air from fuel system on start-up for cleaner operation.
• In-Built Safety and Convenience: Emergency stop device shuts down generator on malfunction. Built-in breaker protects against overloads. Warning lights and safety indicators monitor low oil pressure, high water temperature, insufficient charging, low fuel level, dust, and foreign particles depending on model. Optional earth leakage relay protects users from electric shock on select models.

Options and Accessories

• Two-wheel or four-wheel trailers for easy on-site movement.
• Keyed fuel tank caps and rear doors for security.
• Exhaust gas tail pipes.
• 3-wire single phase output available as an option.

Special Specifications

• Anti-Damage from Salt Water: Special treatment for coastal or offshore use to prevent insulation resistance drop and corrosion.
• Muffler Flange Mounting: Available as an option depending on model.

Notes and Disclaimers

• Specifications are subject to change without notice.
• Colors of products may differ from catalog images.
• Fuel consumption data is based on operation at 75% load.
• Sound levels measured at high-speed no-load operation, averaged at four points 7 meters from the source.
