LANDTOP 80KW-200KW LTP274 Series Brushless AC Alternator
Standard features:
◆The technical performance and mounting dimension of LTP series generators are
international IEC 60034,NEMA MG1-32,ISO8528,CSA C22.2-100,VDE0530 and
national GB755 standards compliant,the quality of prodcts can reach current international standard.
◆Excellent compatibility with drive systems:standard mounting dimensions can be coupled to any
diesel engines from worldwide,many S.A.E flanges and S.A.E drive discs can be easily interchangealble.
◆Easy access for installation and maintenance,including:coupling to engines,connecting for lead
wire,adjustment for AVR,connecting for rectifier,integrating with current transformers.For balanced
rotor with two sealed and quality ball bearing,LTP generators have the featues of little vibration and
low noise.
◆The standard enclosure protection is IP23.
◆And with standard permanent magnet generator excitation system(PMG)
