M O N I T O R I N GACDCVessel Systems Monitor VSM 422The Vessel Systems Monitor VSM 422 is a comprehensivemonitor of four boat systems in one compact meter saving spaceand money.By monitoring DC (including battery state of charge), AC, tanks, andbilge pump, the VSM 422 alerts boaters to problems before theybecome emergencies.The ability to monitor state of charge is critical to safe boating.By using a complex calculation of voltage, amperage, andamp-hours remaining, the VSM 422 is able to provide accurate and timelyinformation about state of charge on the house battery, to help boatersknow when it's time to recharge. The VSM 422 also monitors temperature onthe primary battery with the included Battery Temperature Sensor.AC monitoring includes voltage, amperage, watts, and frequency. Tankmonitoring for up to three tanks includes alarm functionsfor high and low levels, and bilge pump monitoring includes pump active,cycle count, and duration.With its user-friendly interface, intuitive display modes, and versatile casedesign, the Vessel Systems Monitor VSM 422 is an excellent replacement forfour separate system monitors.VSM 422TMNote: Amp-hour function also available in PACIFIC SERIES Battery ChargerOptional Remote Display (page 9).
