Product demand and challenges
And hospital use similar diesel generator sets, but the banks have higher requirements on the environment and interference, so the diesel generator set performance stability, AMF and ATS functions, instant start-up time, low noise, low exhaust emissions, noise immunity various aspects, security, etc. all have demanding requirements.
1, working conditions
Crew can work reliably under the following conditions, the output power and rated power output can work continuously for 24 hours (including every 12 hours of work overload 10% one hour);
Not more than 1000 meters above sea level;
Ambient temperature limit is -15 C °, the upper limit is 40 C °, can choose other environmental unit.
2, low noise operation and low emissions
Ultra-low noise, quiet environment to ensure adequate safety and ease data center staff banking system;
Low exhaust emissions, in order to ensure the cleanliness of the room, to ensure that computer systems and data security.
3, the main and necessary protection devices
Able to start the unit automatically detects battery voltage and alarm , the unit in the following cases automatic delay shutdown : too low , the water temperature is too high , the water level is too low , overload , failed to start , and sends a corresponding signal ;
Emergency shutdown in the following cases : speeding, short circuit, phase , voltage is too high , loss of pressure , low frequency ;
Automatic audible alarm signal in the following cases : low oil pressure , water temperature is too high , the water level is too low , overload , failure to start , overspeed , short circuit, phase , voltage is too high , loss of pressure , low frequency, battery voltage start too low, start the battery voltage is too high , low oil level and the unit has a relay contact alarm system ;
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 < 5 seconds ( adjustable ) , the unit automatically starts (a total of three consecutive automatic start function ) , electricity / unit wholly negative switching time < 10 seconds , the time required to fully meet the load input less than 12 seconds after utility power is restored , the unit to maintain the operation of the cooling 0-300 seconds (adjustable ) automatic shutdown ;
With UPS power systems.
4, the use of permanent magnet brushless excitation alternators, starter motors can provide high capacity, non-linear loads and a host of stator output voltage waveform distortion generated with immunity can increase the generator with nonlinear loads capacity. Stronger ability to withstand short-circuit current (typically up to three times the rated current for 10S).
5, stable performance, high reliability
MTBF of units is not less than 2000 hours;
Technical performance, unit-load voltage tuning range 95-105% of rated voltage;
Unit to the phase-controlled rectifier, switching power supply, UPS power supply, or other load when the power unit when you start 50% of rated load is less than the value of low frequency oscillation does not occur;
Generator at the rated voltage overload 1.5 times the rated current, which lasted two minutes;
Unit with telemetry, remote and remote control function, can local and remote monitoring, collection, processing, recording and reporting of data related to the device.

Solutions
Excellent performance and stable generators, low noise design, equipped with PLC-5220 control system with AMF function , ATS through and connect once to ensure that banks in the main power off , the system must be able to provide alternative power supply immediately. Stability, low noise , engine power in line with European emission standards , as well as features and ATS AMF makes equipment to meet the special requirements of banks. Via RS232 or RS485/422 communication interface equipped to achieve with a computer connection, remote monitoring, remote control, remote communication and telemetry , so automatic , unattended .

Superiority

Complete set of products, programs , and reduce the technical mastery required to make the unit easier to use and easier to maintain ;
· Control system with AMF function, automatic 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 , to meet the daily needs ;
· 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 designed and developed
