Diesel Engine
With WeiChai series engine as the power source. Applicable to 20-150KW generator set.
Optional mechanical or electrical governor, with excellent speed response characteristics
Optional engine speed (1500rpm, 1800rpm, 3000rpm), which reflects the strong power and economic efficiency of the set.
Optimum power output characteristics
Engines are available with three different air intaking methods– natural aspiration, charged and charge inter-cooling.
Synchronous Alternator
•Four-pole rotating magnetic field, self-ventilating radiation system formed by rotor blade 
•2/3 pitch winding, effectively eliminating the sub or ultra harmonic and increasing the paralleling capability
•excellent short circuit withstand ability
•Brushless rotating exciter with rotor/stator exciting system, three-phase rectified bridge
•Insulation grade: H
•Single-ended support mounting way minimizes the vibration of operating generator
•Standard wiring with three-phase four-wire and star connection output
•Auxiliary AVR ensures the steady state voltage deviation compliant with ISO 8528G3
•High quality electromagnetic winding coil
•Integrated design combining the AC output main winding and exciting system
•Rotor damper windings improve the output wave of generator and minimum the wave distortion
•Minimum the generator reactance characteristics
•Maximize the efficiency of electromagnetic induction power generation
Complete Auxiliary Equipment System
•The generator set is installed with internal vibration damper, controller, starting system and auto-monitoring system, to form an integrated power station generator set.
•The internal cushion is made of special rubber
•No need for additional cushion to connect and fix the base to ground.
Apply connection pole for generator set full power output
ATS configuration option
ATS dual-power auto-switch system introduces the specialized dual-power switch with self-locker.
Control System
Controller is a control system independently researched and developed. It applies the microprocessor technology, with the function of measurement, control and protection, and accurately measures various parameters. Cooperating with its self-developed ATS module, it can realize the manual/auto switch control between the generator set and utility power.
Engine Protection

Starting fail shut down
Low oil pressure alarm/shutdown
High coolant temperature alarm/shutdown
Low fuel level alarm/shut.
Charging fault alarm
High/low battery voltage alarm
Internal Control
• Manual/ automatic operation mode option
• Wireless remote start
• Electric door lock start
