April 23, 2013 in Dongguan , China Mobile Group and Prudential Maoming Branch Automation Equipment Co., Ltd. has signed a purchase contract , the total set of 500 LIXISE LXC7220 controller 500 LIXISE PX350 surge plates , 500 LIXISE LXI680 remote wireless data acquisition . For the Company and Move the country to establish a long-term partner to lay a solid foundation. Division I used to do the way the generator control system engineering for China Mobile case here and share with you . At that time , China Mobile Maoming points Male with a 300 Huatai 30KW generators and 200 Cape 30KW generator , I convened a meeting for technical staff on this project

Planning out the following scenario:

Generators must meet the following conditions :

1 , working conditions

The crew can work reliably under the following conditions , the output power and the rated power output can operate continuously 24 hours ( each of which includes 12 hours

10% of the work can overload one hour ) ; altitude not exceeding 1000 meters; ambient temperature limit is -15 C °, the upper limit is 40 C °, optional Other environmental unit.

2 , low noise

Ultra-low noise , quiet enough to ensure that doctors worry about their work environment , in particular to ensure that the operating room for surgery can be quiet activities, while Should ensure that the patient can have a quiet environment for rest and recuperation .

3, the main and necessary protection devices

Starting mode selection unit for automatic startup mode . Crew should have AMF ( automatic mains failure ) function with ATS, to achieve automatic start. When the mains power failure , the starting time delay < 20 seconds ( adjustable ) , the unit automatically starts ( a total of three consecutive automatic start function ) , electricity / machine Groups whole negative switching time < 20 seconds , the time required to fully meet less than 30 seconds into the load , the utility power is restored , the unit runs cold maintain 0-300 seconds

But after the ( adjustable ) automatically shut down.

4 , stable performance , high reliability

MTBF of units is not less than 1000 hours ;Technical performance, unit -load voltage tuning range 95-105 % of rated voltage.


 Excellent performance and stable generators, low noise design, with LXC7220 controller with AMF function , ATS connection through and indeed Paul hospital in once the main power fails, the system must be able to provide alternative power supply immediately. Stability, low noise , in line with European emission standards issued Motive power , as well as features and ATS AMF makes equipment to meet the special requirements of the hospital . Via RS232 or RS485/422 communication interface with , the real Now with a computer connection, remote monitoring, remote control, remote communication and telemetry , so automatic , unattended .

Advantage :

Full range of products , programs , and reduce product technical mastery required to make the unit more simple to use and maintenance ;

The control system has AMF function, can automatically start and automatic shutdown and alarm functions under a number of monitoring ;

Optional ATS, a small unit can be used built-in unit ATS;

Ultra-low noise generation , 30KVA units below the noise level of 7 meters 60dB (A) or less ;

Stable performance, MTBF of units is not less than 2000 hours ;

Small units , matching some of the device in cold areas and high temperatures to achieve regional operational requirements ;

The special needs of some customers can be custom design and development.

Engineering hardware configuration:
30KW generator 300 Taiwan, China and Thailand
200 Cape Generator 30KW.
500 LIXISE LXC7220 Generator controller
500 power surge plates LIXISE PX350
500 LIXISE LXI680 remote wireless data acquisition
