Product Description
TOPS STF224 series Brushless Synchronous AC Alternators

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 pitches 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
Meet leading standards
Electric Features
Installation
Insulation Class H
All regulatory components are made up with special materials and are immersed in lacquer by peculiar tech. Vanish and colophony materials are develop to strengthen the processing and machinery intensity of windings and revolving parts for protecting the alternator work under corrosive environment.
Winding and electric features:
2/3 pith winding design can effectively eliminate the third harmonic wave(3th.9th,15th) of the voltage ,which is the best design of UPS for nonlinear load .Connected with the network in parallel, the structure can restrain excessive currents in the midline
A continuous damp windings 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.
Phone interference
THF(defined by 40thpart of BS4999) <2%.TIF(defined by ASAC50.12)<50
Radio interference
Brushless apparatus and quality AVR ensure little radio interference in transmission. RFI noise filter is also available.
Option
1.       Adapters and drive disk
2.       Single phase
3.       Remote voltage adjust
4.       IP23 enclosure
5.       Space heaters
