AC90LC-3, AC100LC-3, and AC125LC-3 Operations Manual..Being a converter designed from the ground up specifically for the yachting industry, all efforts have been made to produce a system capable of withstanding the marine environment. All system components are packaged in one drip-proof, dust-resistant stainless steel enclosure. Major components are internally modular, allowing a simple exchange in the unlikely event of failure.
AC90LC-3, AC100LC-3, and AC125LC-3 Operations Manual..System cooling is accomplished through a primary, oil-to-water based exchange system as well as a supplemental forced-air cooling system. The main isolation transformer and output filter inductors are immersed in an oil which then circulates through cooling plates where input rectifiers and output transistors (IGBTs) are mounted.
