Control System——DeepSea 6120 Controller 

① Power switch

② Power indicator

③ Run button

④ LCD display

⑤ Emergency stop button

It is a self-starting control module at mains failure and is suitable for controlling a single genset. It provides advanced engine testing and protection functions. This module includes an LCD backlit display that clearly displays the engine running status. The module also includes 7-channel input and 6-channel output. Program can be set through the panel and PC software suite.


Deepsea 6120 controller provides such parameters as generator frequency, idling/overspeed, generator voltage, generator current, engine oil pressure, engine water temperature, flexible fuel level, running hour, battery voltage, start/stop failure, emergency stop, failure to meet operating voltage/frequency, charging failure, magnetic sensor signal loss, low battery voltage, three-phase mains voltage and mains frequency.


Protective functions:

◆ High water temperature

◆ Low oil pressure

◆ High/low voltage

◆ Over speed

◆ Voltage regulator frequency regulator

◆ Emergency stop

◆ Start failure

Product features:

◆ Protection: Automatic start/stop, load switching and genset alarm

◆ Magnetic sensor signal

◆ Parameters setting via PC and panel

◆ Incorporates 4-channel digital input signal and 3-channel analog input signal

◆ 6-channel output signal (4-channel customized output, CAN 6-channel customized output.)

◆ Monitoring of 3-phase generator voltage and mains voltage

◆ Remote loading/unloading

◆ Advanced measurement capabilities

◆ Test button

◆ Switch between mains and genset power

◆ Reasonable structure and button layout

◆ Multiple engine parameters can be tested simultaneously

◆ Module can be configured according to customer demand

◆ IP65 protection (soundproof)

Aosif Soundproof Box-type Genset

Aosif soundproof box-type genset is designed by professional engineers with over a decade of experience.The noise of this kind of genset is controlled at 80-85dB(A) at 1m away, 70~75dB(A) at 7m away, 60~65dB(A) at 15m away.

★ Multiple air inlets/outlets ensure power performance of the genset.

★ Large composite impedance muffler effectively reduces the genset noise.

★ Internal high-performance rubber shock absorber and flexible materials can reduce vibration.  

★ Fuel tank at the bottom can enable the genset to work for 8 hours.

★ Soundproof enclosure is made by cold steel.

★ The best powder coating with chemical surface treatment ensure corrosion resistance and coating quality.

★ Nice appearance and reliable quality.

★ Stainless steel locks and hinges.

★ All-weather operation is available.

★ Fireproof, waterproof and dust-proof

★ High-performance insulation materials can effectively reduce noise.

★ Transparent sight glass allows users to clearly see the content of control panel.

★ Emergency stop button mounted outside the genset to facilitate emergency operations.

★ Coolant filler is set on the top of the enclosure.

★ Lubricant and coolant pipes are installed at the bottom of the genset to facilitate replacement with new lubricants and coolants.

★ Battery is accessible through the access door.
