Inputs: 1x Current 500A, 2x Voltage 0-75V, 3x Resistive 0-65kOhm (Tanks or Temperatures); Simarine´s high precision SC503 active digital shunts measure voltage, current and temperature of a battery or battery bank. Additionally, it allows monitoring tanks for fuel, fresh and gray water. Suitable for monitoring: current draw of heavy consumers (inverters, bow and stern thrusters, anchor winches) current generators (shore power chargers and solar panels). Additionally, it has additional inputs to monitor fuel, fresh, grey and black water tank levels.
