Product Description

250kw 500kw low rpm 15hp three phase diesel generator alternator price

Features:

· ND444 is a range of 4 pole, single or 2-bearing advanced AVR controlled industrial or marine AC generators

· 2/3 pitch winding as standard to avoid excessive neutral currents

· Engines adaptors to SAE 0, 1/2, 1, 2 & 3 and coupling discs to SAE 11.5, 14 & 18 are offered for ND444

· Windings offered are 12-wire reconnectable

· Voltages available range up to 690V

· IP22/23 enclosure protection is standard

· Class ‘H’ Insulation with sever environmental protection as standard

· SX440 AVR as standard

· PMG excitation system is optional

Electric Advantage:

Regulation accuracy when no load to full load

SX460 AVR,+/- 1.5%

SX440,AS440,SA465 ,MX341 AVR,+/- 1.0%

MX321 AVR,+/- 0.5%

External and internal voltage control range

> ± 10%

Overload

Short time load rating of up to 150% of the rated current in 2 minutes.

The alterators can carry a load of 110% for one hour in six.

Dynamic voltage characteristics

The transient dip in voltage when rated load is plac-ed on the alternator at 0.8 power  factor is 15~20%Un.The recovery time is between 0.2 and 1.0 second.

Unbalanced load

The alternators permit an unbalanced load of 25%rated current. The deviation of line voltage is less than5%.

Radio interference suppression

The alternators are supplied with interference sup-pression grade N to VDE 0875.

Parallel operation

During the usually short period required for no-breakload transfer the alternators can be operated in parallelregardless of design variant and manufacturer.

The reactive load sharing is assured by a droop co-mpensation device. Thus equipped, the alternators are suitable for parallel operation with other alternators having the same voltage droop or with a supply system.
