Deep Sea Electronics PLC The DSE704 is an Automatic Mains Failure module with generator monitoring, protection and start facilities. It utilises advanced surface mount construction techniques to provide a compact yet highly specified module. Operation of the module is via three pushbuttons mounted on the front panel with STOP, MANUAL and AUTO positions. Selection of the ‘Auto’ mode is confirmed by LED indicator, and monitors the incoming mains supply (3 phase or single phase). Should the incoming AC mains supply fall below a configurable pre-set limit (180V default), the generator will be started, and load transferred to the gen-set.Chinese Web English Web Tel 0086-0754-88739001 Mobile phone 0086-13556343315 E-Mail 13556343315@139.com QQ number49960677
