SX460, SX440, SX421, MX341 or MX321 AVR
1. The main stator provides power for excitation of the exciter field via AVR
2. Output power of exciter's rotor is input to that of mains through 3-phase full wave rectifier. Two ends of the rectifier are 3. Connected with piezoresistance for restraining surge voltage and avoiding the impact caused by short circuit or parallel synchronization loss.
4. Exciter's Stator is equipped with permanent magnetic steel, it can make generator starting smoothly in any occasions.
5. Voltage regulation (0.5 %) and low frequency protection, exterior voltage adjustment of SX440, MX341 and MX321 suitable for the generator with permanent magnetic generator (PMG).

FEATURES:
1. Any permanent magnetic generators, providing invariable excitation on all occasions.
2. Easy to be connected with power network or other generators. Standard 2/3 pitch windings check excessive midline current.
3. Balanced rotor with single or two sealed ball bearings
4. Convenient installation and maintenance with easy access to terminals, rotating diodes and coupling bolts
5. Wide range of Flange adaptor and single bearing coupling disc
6. All industrial standard generators is IP 23.
TERMINAL AND TERMINAL BOX:
The three-field generator has 12 leads brought out to the terminals in terminal box. The terminals are put on the non drive end. The box is equipped with removable panels

ENGINE ADAPTOR AND COUPLING DISC:
1. HJI Series generators have two kinds construction.
2. HJI Series single-bearing, engine adaptor: SAE0, 1, 2, 3 and 4; Coupling discs: SAE8, 10, 11, . 5, 14 and 18 are available.
3. HJI Series double-bearing, engine adaptor: SAE0, 1, 2, 3, 4 and 5 are available.

VOLTAGE REGULATION:
Voltage regulation refers to the change of voltage from non-load to with power factor ranging from 0.8 to 1 and 3%'s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR.
