Meet leading standards
MECHANIC FEATURES
frame
All industrial standard is IP21, also IP23 is an option, but rates power will decease 5%
Marine standard alternator is IP23, Air filter is an option, but rated power of the alternator will decrease 5% while it is installed.
Axis and Key
All of alternator rotors should pass balance test, whose vibrations are lower than the minimum of BS6861 P. 1, G 2.5 two bearing alternator has a half-key testing balance.
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%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR.
ELECTRIC FEATURES
INSULATION
Insulation Class H
QFW(defined by 40th part 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 disks
2. Single phase
3. Remote voltage adjust
4. IP23 enclosure
5. Space heaters
6. ThermistorS
