MAIN PERFORMANCE data:

1. The standard protection for LJS series generators is IP23;
2. Windings are insulated to class H;
3. Full-damping whole salient construction guarantees generator tobe operated stably in any conditions, and enable it to run under150% rated Speed (2250r/min.) for 2min;
4. LJS generators are provided with a 2/3 winding pitch asstandard, can effectively eliminate the third harmonic (3rd, 9th,15th, etc.), and are therefore perfectly suited to installationswith distorting loads, any easy to operate with the other generatorin parallel.
5. Adjusting rate of stable voltage≤1%, adjusting rate of instantvoltage: -15%ï½ÂÂÂÂÂÂ???? 20%ï¼ÂÂÂÂÂÂ????60%ln, cosФ≤0.4laggingï¼ÂÂÂÂÂÂ????, instant voltage recovery time≤1.5s;
6. Wave aberration rate of voltage THD≤4%, telephone harmony wavefactor THF≤2%, telephone effective factor of TIF≤50.

ENVIRonMENT CONDITIONS:

In the following environments, the generator could runcontinuously:

1. Altitude: do not exceed 1000m.
2. Cooling air temperature:258ï½ÂÂÂÂÂÂ????313K(-15âÂÂÂÂÂÂ????ÂÂÂÂÂÂ????ï½ÂÂÂÂÂÂ????40âÂÂÂÂÂÂ????ÂÂÂÂÂÂ????).
3. Relative air humidity: do not exceed 90%.

Note: If environment conditions exceed the scopementioned-above, please feel free to contact us.

FEATURES:

1. Excellent compatibility with drive systems: standard mountingdimensions can be coupled to any diesel engines from worldwide,many S.A.E. flanges and S.A.E. drive discs can be easilyinterchangeable.
2. Good environmentally-friendly protection system: the standardenclosure protection is IP23, insulation class is H, and LJSgenerators made with advanced manufacturing technologies aresuitable for harsh environments.
3. Reliable and powerful automatic voltage regulators can provideconsistent excitation on all occasions, so the generators can runreliably, and have high performance of magnet on exciter statorwhich can rapidly build voltage while starting; ALL AVR’ s havenumerous features for voltage adjustment, stability adjustment, lowfrequency protection and exterior voltage adjustment.

          StandardAVR: EA460;

          OptionAVR: EA440 (can be suitable for operation inparallel)ãÂÂÂÂÂÂ????ÂÂÂÂÂÂ????EA230ãÂÂÂÂÂÂ????ÂÂÂÂÂÂ????EA08 orEA448(the EA08 and EA448 is suited for auxiliary windings, thus

providing the generator with the best design for nonlinear load,performance on start and short-circuit),

1. LJS generators are provided with a 2/3 winding pitch asstandard, therefore are perfectly suitable for installations withdistorting loads, and easy to be operated with other generators inparallel; Several types of windings are available in 50Hz and 60Hzversions to optimize performance according to the voltage requiredon site and the demands of the application (max. voltages availablerange up to 690 V).
2. LJS generators are provided with three phase as standard, it’seasy to alter the voltage by reconnection for 12-leads on terminalplate, also the units can be run as single phase by changing theoutput connecting (except for LJS354), but single-phase’s poweronly is about 58% of that of three-phase’s; For single-phasegenerator it can be designed for special winding.
3. The damp winding on rotor and the surge suppressor on rectifiercan provide the generator with stability and reliability.
4. For balanced rotor with two sealed and quality ball bearing,LJS generators have the features of little vibration and lownoise.
5. Easy access for installation and maintenance, including:coupling to engines, connecting for lead wire, adjustment for AVR,connecting for rectifier, integrating with currenttransformers.
