Product Parameters

FLD274 Series Specifications(50Hz@ 230/ 400volts; 60Hz@240/ 480volts). Voltage is optional.

Product Introduction

Features

Terminal and Terminal box
The three-field alternator had 12 leads brought out to the terminals in the terminal box. The terminals are put on the non-drive end. The box is equipped with removable panels.

Voltage regulation
Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3% fluctuations of the speed of the engine. Voltage is adjusted via potentiometer of AVR.

Insulation
Insulation Class H.
All wound components parts are all immersed in varnish twice.
 

IP Class

All alternators IP class are IP23.

Winding and electric features
2/3 pitch winding design can effectively eliminate the third harmonic wave(3th.9th,15th) of the voltage. Connected to the network in parallel, the structure can restrain excessive currents in the midline
A continuous damp winding abates surges. The poles and gears of the windings are carefully chosen, this and the 2/3 pitch help to check the wave distortion and output voltage.
 

Shaft and key

All alternators rotors are dynamically balanced to be better than the minimum vibration of BS6861: part 1 grade 2.5. The double bearing is balanced with a half key.

Engine adapter and coupling

All alternators are designed in single bearing and double bearing. The adapter and the drive plate are international standards. It can connect with all kinds of the diesel engine with standard SAE.
 

Overload
Short time load rating of up to 150% of the rated current in 2 minutes. The alternators can carry a load of 110% for one hour in six.

Phone interference
THF is less than 2%. TIF is less than 50.

Every delivered alternator passed strict loading test. 

Our alternators are best used with continuous heavy loads, high temperature and in harsh environments.
