Power Solutions for Marine Application
Following are actual cases of on-board issues resolved using interVOLT’s Power Conditioner series solutions. The issues addressed in these cases are problems that could affect any vessel operating a 12 or 24 VDC system as the primary power source for operating any electrical and electronic equipment.
Case E: Sensitive electronics damaged by voltage dips
Problem: A leisure craft, used extensively for drift fishing, was fitted with the usual array of modern electronic equipment including a chart plotter/sounder. The equipment was connected to the main banks of 12 Volt batteries, also used for engine starting. The plotter/sounder was sensitive to voltage drop caused by the continual stop/starting of the engines. As a result the plotter/sounder had to be re-set every time this occurred, eventually failing due to irrevocable damage to the processor PCB. The customer had to pay for the repair of the equipment on this occasion leading him to find a permanent solution.
Solution: The customer installed an interVOLT SPCi 12-12 VDC 10 Amp Power Conditioner to provide a constant voltage to the equipment. Even when engine cranking resulted in the voltage dropping to less than 9.0 VDC momentarily the unit maintained a constant and uninterrupted supply of 13.6 VDC to the sensitive equipment, thus resolving the problem.
