1 DIESEL GENERATORS ( whisper ). Ultra silent watercooled DIESEL GENERATORS , 3600 & 1800 rpm Mastervolt's comprehensive range of AC. DIESEL GENERATORS is ultra-quiet, compact, easy NEW : to install and reliable. All shipboard con- Digital DIESEL Control veniences such as washer/dryers, air-con- ditioning systems and other AC appliances are now available to you at a push of a button. At the same time, your batteries are being recharged quickly, allowing you to switch back to silent inverter power for the remainder of the day. Comprehensive range whisper GENERATORS are available as 3600 rpm sets (for 50Hz output 3000 rpm) and 1800. rpm (1500 rpm when 50Hz output). The range has now been extended with 3 new Ultra models; an , and 30 kVA model (8, 10 and 25 kVA at 50Hz). Another This type of alternator is the world standard innovation: the entire whisper range is now because of its ability to produce the initial fitted as standard with the new Digital DIESEL power surge required by inductive appliances Systems, not just boxes Control system.

An important advantage offered by Master- generator range: the whisper 3500 for Precise voltage regulation generates optimal volt is the availability of a wide range of example becomes whisper power with a clean sine wave.
