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 to be operated stably in any conditions, and enable it to run under 150% rated Speed (2250r/min.) for 2min;
4. LJS generators are provided with a 2/3 winding pitch as standard, can effectively eliminate the third harmonic (3rd, 9th, 15th, etc.), and are therefore perfectly suited to installations with distorting loads, any easy to operate with the other generator in parallel.
5. Adjusting rate of stable voltage≤1%, adjusting rate of instant voltage: -15%～+20%（60%ln, cosФ≤0.4 lagging）, instant voltage recovery time≤1.5s;
6. Wave aberration rate of voltage THD≤4%, telephone harmony wave factor THF≤2%, telephone effective factor of TIF≤50.

ENVIRONMENT CONDITIONS:
In the following environments, the generator could run continuously:
1. Altitude: do not exceed 1000m.
2. Cooling air temperature: 258～313K(-15℃～40℃).
3. Relative air humidity: do not exceed 90%.
Note: If environment conditions exceed the scope mentioned-above, please feel free to contact us.

FEATURES:
1. Excellent compatibility with drive systems: standard mounting dimensions can be coupled to any diesel engines from worldwide, many S.A.E. flanges and S.A.E. drive discs can be easily interchangeable.
2. Good environmentally-friendly protection system: the standard enclosure protection is IP23, insulation class is H, and LJS generators made with advanced manufacturing technologies are suitable for harsh environments.
3. Reliable and powerful automatic voltage regulators can provide consistent excitation on all occasions, so the generators can run reliably, and have high performance of magnet on exciter stator which can rapidly build voltage while starting; ALL AVR’ s have numerous features for voltage adjustment, stability adjustment, low frequency protection and exterior voltage adjustment.
Standard AVR: EA460;
Option AVR: EA440 (can be suitable for operation in parallel)、EA230、EA08 or EA448(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),
4. LJS generators are provided with a 2/3 winding pitch as standard, therefore are perfectly suitable for installations with distorting loads, and easy to be operated with other generators in parallel; Several types of windings are available in 50Hz and 60Hz versions to optimize performance according to the voltage required on site and the demands of the application (max. voltages available range up to 690 V).
5. LJS generators are provided with three phase as standard, it’s easy to alter the voltage by reconnection for 12-leads on terminal plate, also the units can be run as single phase by changing the output connecting (except for LJS354), but single-phase’s power only is about 58% of that of three-phase’s; For single-phase generator it can be designed for special winding.
6. The damp winding on rotor and the surge suppressor on rectifier can provide the generator with stability and reliability.
7. For balanced rotor with two sealed and quality ball bearing, LJS generators have the features of little vibration and low noise.
8. Easy access for installation and maintenance, including: coupling to engines, connecting for lead wire, adjustment for AVR, connecting for rectifier, integrating with current transformers.

OPTION FEATURES:
1. Interchangeable S.A.E. flanges and S.A.E. drive discs
2. Convenient fitters on air inlets and outlets
3. Protection for windings in harsh environments
4. Different AVR type
5. Different windings
6. Exterior potentiometer
7. Space heaters
8. Stator thermal protection
9. PMG or auxiliary windings
10. Droop current transformers(C.T.)
