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. When the AC mains supply returns to within limits, the module will wait for a configurable, pre-set stabilisation period, and then transfer load back to the mains. The engine will be instructed to stop after a cool-down period. The module’s microprocessor provides a comprehensive list of timers and functions, and access to the settings is via a small Configuration Switch on the rear of the module. Parameter settings can be adjusted using the front panel pushbuttons once in Configuration Mode. Dimensions: 125 X 165 X 28 mm
